[Laparoscopy-assisted vaginal pelvic exenteration].

OBJECTIVE: The aim of the study was to evaluate the feasibility, morbidity and survival outcome of laparoscopy-assisted vaginal pelvic exenteration. PATIENTS AND METHODS: Since 2000, 7 en-bloc pelvic exenteration combining a vaginal or perineal approach and laparoscopic approach have been performed in our cancer center associated with complex laparoscopic reconstruction. All patients but one received previous irradiation. Two patients underwent a total pelvic exenteration; three patients an anterior and middle exenteration; two patients a middle and posterior exenteration. Urinary system was reconstructed with an ileal loop in one case, with a hand-assisted laparoscopic Miami pouch in four cases. Reconstruction of the vagina was performed with an omental cylinder in three cases, with a gluteal thigh flap in one case. A colorectal anastomosis was performed in three patients, one patient had an end colostomy. A mini-laparotomy conversion was necessary in one case because of a pelvic side involvement to perform an intraoperative irradiation. RESULTS: Mean time of the procedure was 6.5 hours with peroperative bleeding less than 500 cm3. Four patients presented minor complications. No revision of the Miami pouch was necessary. Mean length of hospital stay was 27 days. The four patients with a Miami pouch were able to self catheterize at the time of discharge. Mean follow-up was 14 months. Four patients died of the disease (three were metastatic). One patient presented a local recurrence. Two patients are free of disease. DISCUSSION AND CONCLUSION: Laparoscopic or laparoscopy-assisted vaginal pelvic exenteration followed by reconstruction is feasible with curative intent in selected patients.

[Functional results and early experience with the Hautmann neobladder. Comparative analysis of the Toulouse series and the Ulm series].

Orthotopic ileal urinary bladder replacement is an established method after radical standard cystectomy for both genders. In 1986 Hautmann described for the first time the technique of bladder reconstruction using the ileum at the University of Ulm. The W shape of the ileum buffers the coordinated peristaltic waves. The detubularized orthotopic ileal reservoir has been used worldwide ever since because of its technical simplicity, its reduced risk, and its good functional results. The good results published in the literature for this technique were reported by larger centers. With regard to these results, we wondered in 1994 if our smaller department with fewer patients might also offer this technique for male and female patients who had undergone cystectomy. The question was if this method would produce the same results as in large series, provided that patients were adequately selected and surgery carefully performed. This would provide the evidence that the surgical technique is simple, reproducible, and has the same complication rates, such as mortality and morbidity, also for departments with less experience.

Medical and non-medical determinants of prostate cancer management: a population-based study.

Non-medical factors influencing treatment choices in prostate cancer are not well understood. We carried out a population-based study to obtain information on the management of prostate cancer patients. Our study population consisted of 1000 men diagnosed during 1995 from five French cancer registries. We looked at the main treatments performed in the year following diagnosis. Multivariate analysis was used to describe the determinants of the various treatment choices, simultaneously taking into account medical and non-medical factors. The probability of treatment by radical prostatectomy (RP) was 3 times higher in the Tarn area, whereas in the Calvados area the probability of treatment by radiotherapy was almost 6 times higher. The private sector favoured radical prostatectomy and hormonal therapy. In France, as in other developed countries, the initial treatment of prostate cancer varies greatly according to non-medical factors. This type of investigation, if carried out regularly, would make it possible to evaluate changes in practice patterns.

Pubourethral ligaments in women: anatomical and clinical aspects.

The anatomy and histological structure of the proximal (PPUL), distal (DPUL) and intermediate (IPUL) pubourethral ligaments in women was examined to improve the understanding of their roles in female urethral physiology. An anatomical study of the pelvis was carried out in 10 adult female cadavers (60-102 years), the pelvis being removed and frozen prior to dissection. The pubourethral ligaments (PUL) were dissected in sagittal sections in seven specimens and in a frontal section in one specimen; the remaining two pelves were dissected using a hypogastric approach. The location, insertion, direction and histological structure of the ligamentous structures were studied. The PUL were identified in all 10 dissections, being paired, symmetrical, pearly-white, fibrous and resistant to stretching. The bony (parietal) insertion was variable on the posterior surface of the pubis, while the visceral insertion was located on the dorsal aspect of the proximal third of the urethra and neck of the bladder for the PPUL and on the distal third of the urethra for the DPUL. Histologically, the ligaments were composed of dense collagen fibres and bundles of axially orientated smooth muscle fibres. The PPUL was closely associated with the sphincter urogenitalis muscle, whereas the DPUL appeared to reinforce the role of the compressor urethra. It is suggested that the PUL plays an effective role in passive and active suspension of the urethra. The pubourethral ligaments are a constant anatomical entity which should be spared in urethral surgery in women in order to ensure an intact urogenital sphincter.

[Standards, options, and recommendation for external radiotherapy of prostatic cancer: evaluation of the effect of dosage].

CONTEXT: The "Standards, Options and Recommendations" (SOR) collaborative project was initiated in 1993 by the Federation of the French Cancer Centres (FNCLCC), with the 20 French Regional Cancer Centres, several French public university and general hospitals, as well as private clinics and medical speciality societies. Its main objective is the development of serviceable clinical practice guidelines in order to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review, followed by critical appraisal by a multidisciplinary group of experts. Draft guidelines are produced, then validated by specialists in cancer care delivery. OBJECTIVES: Produce clinical practice guidelines for the radiotherapy of prostate cancer using the methodology developed by the Standards, Options and Recommendations project. METHODS: The FNCLCC and the French Urology Association (AFU) designated the multidisciplinary group of experts. Available data were collected by a search of Medline and lists selected by experts in the group. A first draft of the guidelines was written, they validated by independent reviewers. RESULTS: The main recommendations are: 1/ a minimal dose of 70 Gy must be used, whatever the prognostic factors; 2/ it appeared that patients with favourable prognostic indicators (stage T1-2, PSA < or = 10 micrograms/L and Gleason score < or = 6) do not benefit from a dose escalation effect for doses over 70-74 Gy; 3/ patients with intermediate prognosis are the ones who benefit most from the dose escalation effect over 74 Gy, provided they receive exclusive radiation therapy; 4/ whenever possible, patients should be included in controlled trials designed to assess the effects of dose escalation and hormonotherapy.

A modified intussuscepted nipple in the Kock pouch urinary diversion: assessment of perioperative complications and functional results.

OBJECTIVE: To assess the complications and continence of a modified intussuscepted nipple in Kock pouch urinary diversions. PATIENTS AND METHODS: From February 1992 to December 2000, 40 patients (mean age 55.8 years, range 21-74) with bladder cancer (24), gynaecological tumours (eight) or previous lower tract reconstructive surgery (eight) underwent cystectomy and cutaneous continent urinary diversion using the Kock pouch procedure. The first 23 procedures (group I) used Henriet's technique, whereas a modified fixation of the intussuscepted efferent limb was applied in the last 17 (group II). Complications and functional results (focused on continence and the upper urinary tract) were reviewed. RESULTS: The median (range) follow-up was 47.6 (10-124) months; one patient died 4 weeks after surgery. Early complications occurred in 11 (28%) and re-operation was required in two (5%). Of the late complications reported (38%), extussusception (8%) and efferent nipple prolapse (3%) only occurred in group I and required surgical revision. Late complications were minor (15%) including two asymptomatic refluxes and four with stoma sclerosis. The continence rate at 6 months in groups I and II were 78% and 94%, respectively (P = 0.13). CONCLUSION: Efferent limb prolapse and extussusception of the Kock pouch were the main complications requiring surgical revision. Applying the modified nipple fixation the complications can be reduced and reservoir continence improved.

[Local staging of prostate carcinoma with phased array MR imaging: prospective study over 5 years].

PURPOSE: To assess by MRI, using a pelvic phased array coil, the accuracy for staging prostate carcinoma and to correlate the results with the rate of positive surgical margins. MATERIALS AND METHODS: Between January 1995 and December 1999, 176 patients with localized prostate carcinoma underwent a preoperative MRI examination using a pelvic phased-array coil (1 Tesla). MRI and histological results were compared in a prospective study. RESULTS: 131 were classified T2 and 45 were classified T3 at MRI. Pathologic findings showed 103 pT2 and 73 pT3. The accuracy of MRI (extra capsular or vesicle extension) was 75%. The risk for a patient labelled T2 or T3 at MRI to have a positive surgical margin was respectively 13.7% and 31%. CONCLUSION: This study shows that the phased-array coil has a low sensitivity but a good specificity to distinguish between organ-confined cancer or not. It shows that the risk of positive surgical margins is higher for T3 lesions at MRI. The low sensitivity should be improved by using a multi coil phased array.

Retroperitoneal laparoscopic versus open pyeloplasty with a minimal incision: comparison of two surgical approaches.

OBJECTIVES: To compare the complications, hospital stay, and functional results of retroperitoneal laparoscopic (RL) pyeloplasty versus open pyeloplasty (OP) with a minimal subcostal incision. METHODS: From October 1997 to January 2000, 53 consecutive nonrandomized patients underwent 26 RL pyeloplasties, of which 1 was bilateral (group 1), and 28 OP (group 2). The decision between the two techniques depended on the patient's anesthetic ability to tolerate RL, previous ureteropelvic junction surgery, associated renal pathologic findings, and the surgeon's laparoscopic experience. Subjective outcomes as to postoperative pain and convalescence and objective findings on intravenous urography were assessed at 3 months postoperatively in both groups. RESULTS: The mean operating time (165 versus 145 minutes) and mean blood loss (92 versus 84 mL) were similar in both groups. No intraoperative complications occurred in either group; in group 1, 1 patient required open conversion. Postoperative complications occurred in 11.5% of group 1 and 14.3% of group 2. The mean hospital stay was 4.5 days for group 1 and 5.5 days for group 2. At 3 months, 23 patients (92%) in group 1 and 25 (89.2%) in group 2 were pain-free or improved. Intravenous urography showed a patent ureteropelvic junction in all cases and improvement of hydronephrosis in 88.5% of group 1 and 89.3% of group 2. CONCLUSIONS: The incidence of complications, hospital stay, and functional results were equivalent for RL pyeloplasty and OP with a minimal incision, but the return to painless activity was more rapid with laparoscopy in younger patients.

Assessment of the risk of positive surgical margins with pelvic phased-array magnetic resonance imaging in patients with clinically localized prostate cancer: a prospective study.

OBJECTIVES: We assessed magnetic resonance imaging (MRI) performance in the prediction of positive surgical margins (PSMs) before radical prostatectomy in a prospective study correlating the MRI results and pathologic findings. METHODS: Between January 1995 and December 1999, 176 patients (mean age 64.2 years, range 49 to 75), with localized prostate cancer (49 with Stage T1 and 127 with Stage T2) underwent preoperative MRI with a pelvic phased-array coil (Tesla-1, Siemens) at a mean interval of 35 days after randomized transrectal biopsies. The mean preoperative prostate-specific antigen level was 10.9 ng/mL (range 1.2 to 39). The MRI studies and specimen analysis were performed by one radiologist unaware of the clinical and biopsy findings and by one pathologist, respectively. Multivariate analysis was performed to compare the predictive value of MRI staging, prostate-specific antigen value, and preoperative Gleason score to identify the PSM rate. RESULTS: Of the 176 patients, 131 (74%) had Stage T2 disease by MRI and 45 (26%) Stage T3 disease by MRI. Pathologic staging showed 103 with pT2 and 73 with pT3. Overall, the PSM rate of the series was 18%. The PSM rate was 13.7% and 31% for patients with T2 and T3 disease by MRI, respectively. For the T3 MRI cases, the PSM rate was 2.32-fold higher. MRI staging, like the prostate-specific antigen value, was a predictive factor of PSMs (P = 0.05). CONCLUSIONS: The results of this study show that preoperative MRI staging with the phased-array coil may be helpful in predicting the PSM risk in radical prostatectomy candidates with clinically localized prostate cancer.

Impact of a modified apical dissection during radical retropubic prostatectomy on the occurrence of positive surgical margins: a comparative study in 212 patients.

OBJECTIVES: To assess the impact of a modified technique of apical dissection during radical retropubic prostatectomy on the occurrence of positive surgical margins (PSMs). METHODS: Between 1992 and 1998, 212 nonconsecutive patients with localized prostate cancer (57 T1, 155 T2) underwent radical retropubic prostatectomy and were divided into two groups: group 1, 85 patients who underwent surgery before January 1994; and group 2, 127 patients who underwent surgery with the modification of the apical dissection after January 1994. The modified technique consisted of a wide excision of periprostatic soft tissue at the apex, including the bilateral neurovascular bundles. The clinical data (age, prostate-specific antigen, clinical staging) and pathologic findings (pathologic staging, Gleason score, PSM rate) of the two groups were compared. RESULTS: No significant difference was found between the two groups regarding the median prostate-specific antigen level (10.8 ng/mL and 9.5 ng/mL), Gleason score, and pathologic staging. Overall, the PSM rate was 53% in group 1 and 20.5% in group 2 (P <0.001). The number of PSMs decreased 2.6-fold in group 2. The PSM rate was significantly reduced at the apex with the new technique (group 1, 33.3%; group 2, 7.7%; P = 0.008). The PSM rate expressed with the odds ratio was 4.4-fold lower for patients in group 2 than for those in group 1. CONCLUSIONS: The modified apical dissection in radical retropubic prostatectomy significantly improves the PSM rate in patients with localized T1-T2 prostate cancer.

Assessment of morbidity and functional results in bladder replacement with Hautmann ileal neobladder after radical cystectomy: a clinical experience in 55 highly selected patients.

OBJECTIVES: To analyze the morbidity and functional results of the ileal neobladder in a series of 55 highly selected patients. The ileal neobladder is a commonly used technique for orthotopic bladder reconstruction after radical cystectomy in both sexes. Good results have been published from Ulm University, where the technique was popularized. METHODS: From February 1994 to June 2000, 55 patients (47 men and 8 women), 32 to 75 years old (mean age 58) with good performance status (American Society of Anesthesiologists score 1 and 2), underwent radical cystectomy for bladder cancer and Hautmann ileal neobladder reconstruction. Functional assessments were done at 3 months and every 6 months thereafter, with special attention to urinary continence and upper urinary tract status. RESULTS: The median follow-up was 28.8 months (range 8 to 96). One perioperative death occurred. Early complications occurred in 23.6% without repeated surgery and late complications occurred in 25.4%, with three repeated operations for occlusive syndromes. The daytime and nighttime continence rates at 3, 6, and 12 months were 59.6%, 80.8%, and 88.5% and 38.5%, 61.5%, and 78.8%, respectively. The overall continence rate in patients younger than 70 years old was 80.8%. Three patients required self-catheterization to empty their neobladder. Eleven patients died of metastatic evolution of their bladder cancer or intercurrent disease at 6 to 36 months. CONCLUSIONS: In highly selected patients, the ileal neobladder provides good functional results regarding continence with an acceptable complication rate. In this series, the results were comparable to those reported in the referent institution.

Multi-institutional study of complications in 1085 laparoscopic urologic procedures.

OBJECTIVES: To assess the incidence of the complications in laparoscopic urologic procedures with regard to clinical presentation, etiology, and treatment. METHODS: From January 1994 to December 2000, 1085 laparoscopic procedures were performed at three institutions in 1075 patients (702 men, 373 women). A referent surgeon for laparoscopy was at each institution. The major procedures were radical prostatectomy (n = 232), different types of nephrectomy (n = 171) and nephroureterectomy (n = 15), adrenalectomy (n = 130), pyeloplasty (n = 61), pelvic lymph node dissection (n = 130), genitourinary prolapse repair (n = 86), bladder neck suspension (n = 104), and treatment of benign kidney pathologic findings (lithiasis, cysts, and diverticula, n = 55). The complications were listed by incidence and etiology according to the procedure attempted. RESULTS: A total of 75 complications (6.9%) occurred in this multi-institutional series. The mortality rate was 0.09%, and the conversion rate was 2.1%. Vascular (n = 7) and visceral injuries (n = 11) occurred in 24% of complications. Hematomas (n = 10), urinomas (n = 8), and wound infections (n = 7) at the trocar sites were the most frequent postoperative surgical complications. Pulmonary disorders (n = 9) and urinary infections (n = 9) were predominant in the postoperative medical problems. CONCLUSIONS: Even though it appears to be minimally invasive, laparoscopy remains major surgery, with serious complications possible. These complications should be preventable with better mastery of the different steps of the procedures. Increased knowledge of the possible complications is essential for urologists in laparoscopic training and may help them improve their learning curve.

A population-based study on radical prostatectomy in France.

There has as yet been no descriptive study of the practice of radical prostatectomy in the general population in France. The objective of this work was to investigate the use of radical prostatectomy (RP) in France and its determinants and geographic variations. A total of 175 radical prostatectomies was identified in a random sample of 798 cases of prostate cancer recorded in 1995 by four cancer registries, in the departments of Bas-Rhin, Calvados, Isère and Tarn. Tumour characteristics, diagnostic procedures and histopathological results were analysed. Multivariate analysis by logistic regression was used to take into account age, prostate specific antigen (PSA) levels and clinical stage in order to study variations between geographical departments and sectors of activity (private or public). The mean age of the patients at the time of diagnosis was 65.3 y (range 46-76). Median PSA level was 18.2 ng/ml (range 1-184). Diagnosis was made by randomised biopsies in 73.8% of cases or by transurethral resection (6.9%). Clinical stage was classified T(1) (22.3%), T(2) (64%), T(3) (8.6%), N(+) (0.6%) and unknown (4.5%). The histopathological result was pT(2)N0 in 46.3% of cases, pT(3)N0 in 40%, pT(4)N0 in 1.7%, pT(x)N(+) in 8.6% and unknown in 3.4%. Adjuvant therapy (radiotherapy 13.7%, hormonal treatment 13.7% or both 3%) was administered in 54 patients (31%). Logistic regression showed that the probability of undergoing RP was three times higher in one department than in the other departments, and was 2.6 times as high in the private sector. This study on the practice of RP is the first performed in the general population in France. It shows that practice differs according to geographical region and sector of activity, indicating that schools of thought and medical culture vary within the same country.Prostate Cnacer and Prostatic diseases (2001) 4, 118-123

A population-based study on management of prostate cancer in four regions of France.

In France, as in other European countries, management of prostate cancer in the population is rather variable. The objective was to analyse diagnosis and treatment modalities of prostate cancer in patients from French cancer registries.A sample of 803 patients with prostate cancer diagnosed in 1995 was drawn at random from cases recorded in four cancer registries in the geographical regions of Bas-Rhin, Calvados, Isère and Tarn. Diagnosis, clinical staging and treatment were analysed by questionnaire. Multivariate analysis by logistic regression was used to describe medical determinants (age, PSA, clinical staging) of the various treatment choices.The mean age of the patients was 71.6 y (range 46-94 y). Clinical staging showed 60% T(1-2) tumours, 15% T(3-4) and 17% N+or metastases. PSA rate (median 18.2 ng/ml) was assessed in 92.4% of patients. Prostate cancer was diagnosed by prostate biopsy in 63% and by transurethral resection of the prostate (TURP) in 32% of patients. The main treatments were radical prostatectomy 22%, radiotherapy 19.4%, hormonal therapy 33%, TURP alone 17.7% and expectant management 6%. The method of treatment was unknown in 5.7% of cases. Adjuvant radiotherapy or hormonal therapy had been used in 31% of cases. Logistic regression analysis showed that radical prostatectomy was most often performed in patients aged <60 y, three times more frequently for T(2) tumour and for PSA between 4 and 20 ng/ml. Radiotherapy was the most frequently applied treatment for patients aged between 65 and 75 y, especially in T(3) tumours.Approximately 75% of the patients in the study underwent a specific treatment for prostate cancer with a curative intention in 40%. This study provides a baseline to clinicians and public health authorities on the management of prostate cancer in France with recent data. This survey will be useful to compare future descriptive analysis and to provide data regarding changing clinical practice.Prostate Cancer and Prostatic Diseases (2001) 4, 154-160.

Haemodynamic changes during retroperitoneoscopic adrenalectomy for phaeochromocytoma.

Surgical removal of phaeochromocytoma may be accompanied by acute cardiovascular changes. We report the haemodynamic changes in seven patients with retroperitoneal laparoscopic adrenalectomy for phaeochromocytoma. Transient hypertension (systolic pressure (SBP) > 160 mm Hg) was observed in all patients during manipulation of the tumour, in two patients during pneumoretroperitoneum insufflation, and in one patient during intubation. Small doses of nicardipine were sufficient to control these episodes of hypertension. Transient hypotension (SBP < 100 mm Hg) was observed in two patients during exsufflation and in one patient during repositioning to the lateral position. Our observations suggest that this approach provides relative haemodynamic stability, especially during pneumoretroperitoneum insufflation.

Radical cystectomy in patients older than 75 years: assessment of morbidity and mortality.

OBJECTIVE: We have reviewed our surgical experience to assess intra- and postoperative morbidity and mortality in 25 patients 75 years old or older with invasive bladder cancer who underwent radical cystectomy and urinary diversion or bladder substitution. METHODS: Between January 1993 and February 1999, of 190 patients who underwent radical cystectomy, 23 men and 2 women were aged from 75 to 87 (median 79) years. Urinary diversion was performed in 23 cases and bladder substitution in 2. All patients had significant comorbidity and 15 patients were ASA II and 10 ASA III. RESULTS: Median operating time was 4 h. Perioperative mortality rate was 4%. Intraoperative, early and late postoperative complications occurred in 15, 16 and 6 patients, respectively. The most common early complications were pyelonephritis (32%), disorientation (20%), additional pulmonary infection (20%) and prolonged ileus (32%). No secondary procedures were necessary. The most common late complication was ureteroileal anastomotic stricture (16%). The median hospital stay and intensive care unit stay were 24 and 14 days, respectively. With a median follow-up of 14 (5-50) months the overall mortality rate was 32%. CONCLUSIONS: Radical cystectomy can be performed in elderly patients with acceptable perioperative mortality and morbidity. However, because of the high incidence of minor medical complications, hospital stay is often prolonged.

The tension-free transvaginal tape procedure in the treatment of female urinary stress incontinence: a French prospective multicentre study.

OBJECTIVE: To evaluate in a prospective multicentre study (five centres) the preliminary results regarding efficacy and morbidity of the new tension-free transvaginal tape (TVT) technique in the treatment of urinary stress incontinence (USI) in women. METHODS: From November 1996 to May 1999, 52 women of mean age 64 (range 37--91) years underwent the TVT procedure to treat isolated grade 2 or 3 USI (44 cases) or grade 1 or 2 USI associated with uterine or rectal prolapse surgery (8 cases). Twenty-nine patients (55.8%) presented recurrent USI (1--4 previous procedures). Clinical data showed urethrovesical junction hypermobility in 35 cases (67.3%), isolated intrinsic sphincter deficiency (ISD) in 17 cases (32.6%) and pelvic organ prolapse in 8 cases. Urodynamics confirmed ISD in 27 cases (51.9%) with a mean urethral closure pressure of 18.5 (range 7--25) cm H(2)O. All data were collected by surgeons on a questionnaire. RESULTS: The surgical procedure was performed under spinal cord anaesthesia in 82.7% of patients (local anaesthesia 11.5%) with a mean operation time of 30 (range 20--60) min for TVT implantation. Six bladder injuries (11.5%) were identified and the needle was repositioned. Mean hospital stay was 2.5 (range 1-7) days in the group who underwent TVT alone. Mean follow-up of continence was 15.2 (range 6--36) months: 83% of patients were dry and 17% were improved. Nine patients (17.3%) required self-catheterization for 2--10 days postoperatively. No recurrence of USI, defect healing or tape rejection were reported. CONCLUSION: TVT is a new technique for the surgical treatment of USI which is useful for recurrent cases. The advantages are simplicity, low morbidity, reproducibility and reduced operative time. These early results indicate the technique is effective in correcting incontinence and is locally well tolerated. But these are preliminary data and the long-term outcome on USI and the urethra is needed.

[The new uretero-ileal anastomosis technique in Hautmann ileal neobladder].

OBJECTIVE: Hautmann neobladder is one of the most widely bladder replacement techniques in the two sexes. The uretero-ileal stenosis rate is estimated to be 11% with the initial CAMEY-LE DUC technique. A new anastomosis technique is presented in order to improve this postoperative complication. MATERIALS AND METHODS: Two 5 to 10 cm ileal segments are prepared at the two extremities of the W of the neobladder to receive the largely spatulated ureters. The anastomosis is performed directly on the ileal resection margin, in a strictly retroperitoneal position. Between December 1996 and December 1998, the technique was performed in 89 patients including 19 women. One hundred and sixty six renal units (RU) were analysed by preoperative renal ultrasound, repeated after 1, 3 and 6 months and then every 6 months. Urine culture was performed monthly for 6 months. RESULTS: Thirteen RU were dilated (grade II and III) preoperatively (7.8%). No secondary anastomotic stenosis was observed with a mean follow-up of 5.8 +/- 7.6 months. Of the 166 RU examined, 129 were normal, 13 preoperative dilatations were improved and 24 RU presented minimal postoperative dilatation (grade I). Ileo-ureteric reflux was observed on the postoperative retrograde cystography in two cases. The only complication was acute pyelonephritis (1.1%) at 1 month. 90% of urine cultures were sterile after 6 months. CONCLUSION: Modification of uretero-ileal anastomosis by the "double chimney" technique is performed without tension by placing the two ureters in an anatomical position without plication or torsion. Preservation of the ureteric blood supply contributes to the low complication rate and a decreased risk of stenosis. However, the technique needs to be validated by analysis of the results with a longer follow-up.
