Adrenal incidentalomas: surgical treatment in 28 patients and update of the literature.

INTRODUCTION: Adrenal masses discovered by imaging techniques for reasons unrelated to adrenal diseases are called adrenal incidentalomas (Al). The aim of this study was to find out the clinical outcome of 28 patients operated for incidentally discovered adrenal mass and to update the literature concerning this topic. PATIENTS AND METHODS: From September 1976 to December 1999 we operated on 28 patients for adrenal incidentaloma. Adrenal masses were unilateral in 25 cases and bilateral in 5. Average age was 57 years (range 10-73). Hormonal study was performed in all patients. All patients underwent adrenalectomy by the transabdominal subcostal approach. RESULTS: Histopathology assessed the adrenal masses as primary in 19 patients and secondary in 9. 24-hour urinary vanillylmandelic acid (VMA) excretion was elevated in 2 patients. Adrenal insufficiency was detected in 1 case. Average tumor diameter resulted 5.8 cm (range 2-17). Histopathologic features of primary adrenal masses included pheochromocytoma in 5 cases, cysts in 4, myelolipomas in 3. nodular hyperplasia in 2, tuberculous mass in 1, cortical adenoma in 1, extra-bone marrow hemopoiesis in 1, cortical carcinoma in 1 and neuroendocrine tumor of the adrenal medulla in 1. The 9 adrenal metastasis resulted by renal cell carcinoma in 7 patients, urothelial carcinoma of the upper urinary tract in I and primary renal lymphoma in 1. Average follow-up was 68 months (range 6-246). Patients alive were 18 (64%), deal 10 (36%). Of the 19 patients with primary adrenal tumors 16 (84%) were alive and disease free and 3 (16%) died (I for disease and 2 for reasons unrelated to the primary tumor). Of the 9 patients with adrenal metastasis 2 (22%) were alive (I disease free and I with progression of the disease) and 7 (78%) died for disease. Replacement therapy for adrenocortical hormones was given 5 patients. CONCLUSIONS: Management of Al need CT or MRI and hormonal investigation in order to detect malignancy and subclinical hypersecretory syndromes. Subclinical functional adrenal masses, single adrenal metastasis and primary nonhypersecretory adrenal tumors sized 4 cm are treated by surgery. A close morpho-functional follow-up is indicated for primary adrenal incidentalomas when nonhypersecretory and smaller than 4 cm.

Primary lymphoma of the epididymis: case report and review of the literature.

OBJECTIVE: To report an extremely rare clinical pathological observation of a case of primary lymphoma of the epididymis, without testicular or systemic involvement, and to update the relevant literature. MATERIALS AND METHODS: A 25-year-old white male patient complaining of right scrotal pain was referred to our department. Clinical examination detected a hard painful mass at the right epididymal head. Epididymitis was diagnosed and conservative therapy with antibiotics and anti-inflammatory drugs was given. After 2 months of therapy the patient was admitted to our department because a tumor was suspected. Tumor markers were normal. Right scrotal exploration was performed through a standard inguinal incision. The epididymal head was completely replaced by a hard white mass. Fresh frozen sections indicated a malignant tumor. Right radical orchiectomy was performed. RESULTS: High-grade primary epididymal non-Hodgkin's lymphoma with diffuse large cells (group G according to the Working Formulation) was diagnosed. Clinical pathological staging detected stage IE (extranodal) primary epididymal lymphoma. The patient was referred to the Hematologic Unit for combined chemotherapy, according to the VACOP-B protocol. After an 18-month follow-up the patient is well and disease free. CONCLUSIONS: When an epididymal mass does not benefit from medical treatment, scrotal exploration and fresh frozen sections of the lesion should be done. The possible bilateral involvement by primary epididymal lymphoma has to be kept in mind. Radical orchiectomy is the treatment of choice for primary lymphoma of the epididymis. Adjuvant chemotherapy is indicated in high-grade malignant lymphoma. Prognostic parameters of the disease may be the grade of malignancy and the size of the tumor.

Prognostic value of renal cell carcinoma nuclear grading: multivariate analysis of 333 cases.

OBJECTIVE: To evaluate the independent predictive value of the nuclear grading system according to Fuhrman in relation to the disease-specific survival of patients with renal clear cell carcinoma. MATERIAL AND METHODS: 333 patients who underwent radical nephrectomy for renal clear cell carcinoma between 1983 and 1999 were evaluated. In all patients we retrospectively studied nuclear grading, average tumor size, multifocality, pathologic stage of primary tumor, vein invasion, lymph node involvement and distant metastases. The Kaplan-Meier method was applied to evaluate disease-specific survival rates. The log rank test was used to compare survival curves and for univariate analysis. The Cox proportional hazards model was used for the multivariate analysis. RESULTS: Histologic grade was G1 in 83 cases (25%), G2 in 117 cases (35%), G3 in 110 cases (33%) and G4 in 23 cases (7%). Our data showed that nuclear grading according to Fuhrman is related to medium tumor size (p < 0.0001), pathologic stage of cancer (p < 0.001), venous system invasion (p < 0.001), lymph node involvement (p < 0.001) and distant metastases (p < 0.001). The disease-specific survival after 5 and 10 years was 94 and 88%, respectively, in patients with G1, 86 and 75% in patients with G2, 59 and 40% in patients with G3 and 31% in patients with G4 (log rank p value < 0.0001). Multivariate analysis showed that nuclear grading by Fuhrman has a prognostic independent predictive value (hazard ratio = 1.8461, p = 0.002). CONCLUSIONS: Nuclear grading is an important independent predictive factor of disease-specific survival in patients with renal cell carcinoma.

Renal vein and vena cava involvement does not affect prognosis in patients with renal cell carcinoma.

OBJECTIVES: The prognostic value of tumor extension into the renal vein or vena cava is still a controversial issue. The aim of this study is to report our experience with radical surgery in patients with renal cell carcinoma (RCC) extending into the renal vein or subdiaphragmatic vena cava. METHODS: We evaluated 142 patients with RCC involving the renal vein or inferior subdiaphragmatic vena cava. RCC had extended into the renal vein in 118 patients and into the inferior vena cava in the remaining 24. Radical nephrectomy was performed in all cases with renal vein invasion. Radical nephrectomy with cavotomy and tumor thrombus removal was carried out in all cases with inferior subdiaphragmatic vena caval invasion. Cause-specific survival was calculated by means of the Kaplan-Meier method. The log rank test was used for survival comparisons and univariate analysis. RESULTS: The 5- and 10-year cause-specific survival rates were 51.5 and 39%, respectively, in the group of patients with tumor extension into the renal vein and 33.4% in those with inferior vena caval involvement. In 52 patients (44%), RCC extended only into the renal vein. In the remaining 66 patients, renal vein invasion was associated with other adverse prognostic factors. Life expectancy was lower for patients with other concurrent adverse prognostic factors than for those affected by renal vein involvement alone (p < 0.0001). In the latter group, survival expectancy was similar to those with stage T2N0M0 tumor. In 7 cases (29%), inferior vena caval invasion was not associated with other adverse prognostic factors. In the remaining 15 patients (71%), vena caval involvement was associated with other adverse prognostic factors. Concurrence of other adverse prognostic factors with vena caval invasion significantly decreased the disease-specific survival expectancy in comparison with the patients in whom vena caval involvement was the main prognostic factor (p = 0.008). In these patients, disease-specific survival was similar to those with stage T2N0M0 tumor. CONCLUSION: Renal vein or inferior subdiaphragmatic vena caval involvement does not significantly affect prognosis in patients with RCC.

The pathophysiology, diagnosis and therapy of the transurethral resection of the prostate syndrome.

In this article, the authors analyze a syndrome first described by Creevy in the 1940s, which may occur during a transurethral resection of the prostate (TURP). The syndrome is characterized by cardiocirculatory and neurological problems due to rapid changes in intravascular volume and plasma solute concentrations caused by excess irrigating fluid absorption. This article reviews the available literature and reports on the experience of our clinic, a specialist department in the physiopathology, diagnosis, therapy and prevention of TURP syndrome.

Nephrogenic adenoma of the urinary bladder: our experience and review of the literature.

OBJECTIVE: To assess our experience in the treatment and clinical outcome of bladder nephrogenic adenoma (NA) updating and reviewing the literature concerning this issue. PATIENTS AND METHODS: From September 1976 to June 1999, bladder NA was diagnosed in 8 patients: 6 men and 2 women with a 3:1 male ratio, aged 26-80 (mean 58.3) years. Follow-up ranged from 4 to 194 (mean 93.5) months. RESULTS: NA was associated with transitional cell carcinoma in 3 cases. Predisposing factors were assessed in all patients. Previous surgery of the lower urinary tract was detected in 5 cases: ureterocystoneostomy in 2, partial cystectomy in 1, repair of vesicouterine fistula in 1, and multiple urethroplasties in 1. Previous endoscopic treatments were carried out in 2 patients, transurethral resection of the prostate in 1 and repeated transurethral resection of the vesicle in the other. A history of intravesical instillation of bacillus Calmette-Guérin was assessed in 1 case. Patients complained of irritative voiding symptoms in 6 cases and hematuria in 2. Endoscopically, the lesions appeared polypoid and multifocal in 5 patients, and flat and single in 3. The lesions were removed endoscopically, providing relief of symptoms in all cases. Histopathology assessed the diagnosis of nephrogenic adenoma, detecting focal atypic cells in 1 case only. Five patients (63%) relapsed 2-24 months after management. Recurrences were also treated endoscopically. CONCLUSIONS: Clinical and endoscopic features of bladder NA are not specific, simulating urothelial carcinoma or chronic cystitis. Endoscopic management allows accurate histological diagnosis and provides long-lasting relief of symptoms. NA needs careful and long-term follow-up, because of the high risk of recurrences and the potential neoplastic degeneration of the metaplastic urothelium.

The TURP syndrome: importance of expiratory ethanol measurement and high serum levels of glycine.

OBJECTIVE: In a prospective study it was our intention to evaluate the reliability and the predictive value of expiratory ethanol for the early detection of the occurrence of TURP syndrome and emphasize the role of the serum levels of glycine in clinical manifestation. METHODS: We studied 30 patients scheduled for elective traditional transuretral resection of the prostate performed with subarachnoid anesthesia. Serum sodium and glycine concentrations, serum osmolality and end-expiratory ethanol levels were monitored at scheduled intervals. Continuous heart rate and blood pressure monitoring was performed during the perioperative period in the operativing room and, later, in the recovery room. Occurrence of cardiocirculatory, respiratory and neurologic symptoms were recorded. Statistics included Bonferroni's t-test and Fisher's exact test. A decision level plot for end-expiratory ethanol level was performed for the choice of predictivity criterion. RESULTS: In our population we identified three groups of patients: Group I (15 patients) in which no symptom was recorded; Group II (6 patients) in which non-specific anesthesia-related symptoms occurred; Group III (9 patients) in which TURP syndrome of various degree of severity was observed. In this group of patients changes in serum sodium and glycine concentrations, serum osmolality and end-expiratory ethanol levels were significantly different compared with the other two groups. In regard to end-expiratory ethanol levels, we identified a cut-off point at 0.05 mg/ml. In Group III two patients developed transient blindness. These patients had the highest serum glycine concentrations (> 4000 mumol/ml). Mortality was nil. CONCLUSIONS: Our data show the reliability and accuracy of end-expiratory ethanol levels as a predictive test of the occurrence of TURP syndrome. Further, we emphasize the role of serum glycine concentration in the occurrence of neurologic symptoms related to the transurethral resection of the prostate.

Experience in the surgical treatment of Fraley's syndrome.

OBJECTIVE: To report our 20-year experience with nephron-sparing surgery in the treatment of Fraley's syndrome. MATERIALS AND METHODS: From September 1976 to July 1996, 6 women, 18-43 years old, underwent surgical treatment. All patients had been suffering debilitating right flank pain for at least 6 months before the operation. Diagnosis was in call cases made with the use of intravenous pyelography and renal arteriography, which showed a vascular impression on the superior infundibulum with secondary dilatation of the upper pole calyx. This was localized only on the right side in 5 cases, while in 1 it was bilateral though more severe on the right. Ipsilateral nephroptosis was observed in 2 of the patients. In 2 cases in whom the superior infundibulum was sufficiently long, an infundibulo-infundibulostomy with everted flaps was performed. In a case in whom a short infundibulum was compressed between a venous and an arterial branch, Fraley's infundibulopyelostomy was carried out. In 1 patient in whom the infundibulum was compressed by the anterior-superior segmental artery, a Heineke-Mikulicz-type infundibulorrhaphy was combined to vasopexy. In the remaining 2 cases, the infundibulum was not cut: in one case, a simple vasopexy of two vascular branches was carried out, while in the other, a minor arterial branch was ligated and divided. In 4 patients, nephropexy was also performed. RESULTS: No significant intra- or postoperative complications were observed. Follow-up averaged 102.5 months. Pain relief was complete in 5 cases, in whom disappearance of the vascular impression was also radiologically demonstrated. Only 1 patient, who underwent infundibulorrhaphy and vasopexy, experienced occasional flank pain and urinary infection after the operation, with just a slight improvement in the excretory urogram. CONCLUSIONS: Surgical treatment of Fraley's syndrome is indicated only in symptomatic and/or complicated cases; in relation to the type of obstruction and the anatomy of the intrarenal structures, whether excretory or vascular, several effective nephron-sparing techniques can be selected.

General state of health and psychological well-being in patients after surgery for urological malignant neoplasms.

OBJECTIVE: To evaluate the general state of health and the psychological well-being in a group of 155 patients after surgery for urological malignant neoplasms. MATERIALS AND METHODS: Surgery was performed in 55 patients for renal cell carcinoma, in 54 for invasive bladder carcinoma, in 30 for adenocarcinoma of the prostate, and in 16 for squamous penile carcinoma. All patients were invited to self-compile the General Health Questionnaire (GHQ) - 12 items according to Goldberg and the Hospital Anxiety and Depression Scale. Results were compared with those in a group of patients who underwent retropubic prostatectomy for benign prostatic hyperplasia. RESULTS AND CONCLUSION: The general state of health was significantly more impaired in neoplastic patients than in the control group. Levels of anxiety were significantly higher but depression levels were similar in both groups. As far as the type of tumor is concerned, patients who underwent radical cystectomy for bladder carcinoma and those treated with partial penectomy for squamous penile carcinoma showed a significant impairment of the general state of health compared with controls. Higher levels of anxiety were observed in patients who underwent ileal conduit after radical cystectomy, in those treated with radical prostatectomy for prostate cancer and in those who underwent partial penectomy. Significantly higher levels of depression than in the control group were observed only in patients with ileal conduit.

Treatment of retroperitoneal fibrosis with tamoxifen: case report and review of literature.

OBJECTIVE: To evaluate the efficacy of tamoxifen in the treatment of idiopathic retroperitoneal fibrosis in one patient and to review the results reported in the literature. METHODS: A 68-year-old man with idiopathic retroperitoneal fibrosis and obstructive acute renal failure was admitted to our department. Bilateral ureteral stents were placed and tamoxifen 20 mg daily p.o. was started. RESULTS: The ureteral stents were removed five months after tamoxifen therapy. IVP demonstrated normal appearance of the ureters nine months after medical treatment. An MRI scan showed an important decrease of the fibrotic periaortic mass at 12 months and then we stopped tamoxifen. CONCLUSIONS: Actually tamoxifen represents an attractive and safe choice of medical treatment for retroperitonea fibrosis, particularly in the acute stages. Nevertheless, the duration of treatment, the effectiveness and the persistence of the results are still uncertain because few cases have been reported in the literature.

[Our experience in the treatment of retroperitoneal fibrosis].

To discuss retroperitoneal fibrosis (RPF) etiopathogenesis and to report on our experience in the treatment of the disease. From 1977 to 1998 26 RPF patients, 15 idiopathic (I group) and 11 secondary (II group), entered our clinic. Vascular risk factors of the I group were cigarette smoking (73.3%) and arterial hypertension (46.6%). Etiologic factors of the II group were aorta abdominal aneurysm (four cases), radiation therapy for female genital tract cancer (four case), aorto-bifemoral bypass for aorta aneurysm (two cases), retroperitoneal non-Hodgkin lymphoma (one case). Treatment performed for idiopathic disease was medical in eight cases (alone in two, with endourologic measures in six) using corticosteroids in five and tamoxifen in three; only endourological in three and surgical in four (nephrectomy in two patients, ureterolysis and ureteroneocystostomy in one, pyeloureterolysis in one) with perioperative corticosteroid treatment in three cases. Treatments performed in patients with secondary disease were endourologic in five surgical in three (ureteroureterostomy, ureteroneocystostomy, pyeloureterolysis and pyeloreduction), medical with corticosteroids in two; one patient affected by perianeurysmatic fibrosis did not require any treatment because of disease's spontaneous recovery. Medical treatment induced symptom remission and plaque reduction in all patients. Surgery determined complete recovery in all patients except for one in whom the disease relapsed with controlateral urinary tract involvement. Medical RPF treatment for idiopathic or secondary disease is effective in the first stage. Disease management with tamoxifen is easy to perform, safe and effective. In the steady state of RPF the best results are obtained by surgery and perioperative glucocorticoid therapy reduced significantly fibrosis' relapse.

Penetrating trauma to the scrotum and the corpora cavernosa caused by gunshot.

The authors describe a case of gunshot wound of the male genitalia by two low-velocity bullets. The first bullet caused a lesion of the right testicle and came out of the right hemiscrotum; the second one had penetrated the left gluteal region with no exit wound. The penile ultrasound confirmed the presence of the bullet at the root of the right corpus cavernosum. The patient underwent exploratory surgery, drainage of the voluminous bilateral scrotal hematoma, and suture of a laceration of the right-testicle cranial portion. Due to the absence of active bleeding, voluminous hematoma and serious injuries in the corpus cavernosum, no surgical removal of the bullet in the right corpus cavernosum was required. The patient regained a normal sexual function 1 month after the operation.

Surgical treatment of penile carcinoma: our experience from 1976 to 1997.

OBJECTIVE: The purpose of this work is to evaluate our experience with the surgical treatment of penile squamous carcinoma, analyzing the therapeutic results in terms of local recurrence rates, survival and mortality rates. MATERIAL AND METHODS: From 1976 to 1997, 47 patients were treated at our institution for carcinoma of penis. Treatment of primary tumor was conservative in 8 patients (17%). Partial penectomy was performed in 30 patients (63.8%); total penectomy in 5 (10.7%) and emasculation in 4 (8.5%). Pathological stage was pTis in 2 cases (4.2%), pT1 in 20 (42.6%), pT2 in 21 (44. 7%) and pT3 in 4 (8.5%). The tumor was clinically overstaged in 13 patients (27.7%) and understaged in 4 (8.5%). Bilateral inguinal lymphadenectomy was performed only in 4 patients clinically N+ (pN2) and in 3 clinically N0 (pN0). RESULTS: Local recurrence rate was 43% in the patients with pT1 stage tumor treated conservatively. No local recurrence was observed after penectomy. 19 patients (40.4%) are alive and disease-free; 17 patients (36.2%) died of the tumor and 11 patients (23.4%) died of other causes but disease-free. Mean follow-up is 69.43 months. The overall 5-year survival rate was 34%. CONCLUSION: Partial penectomy gives better results than conservative treatment in the local management of the T1 stage tumor. Survival and mortality rates are related to both pathological and histological stages. The high mortality rate observed in the pT2 stage tumors in our experience might be related to the fact that in this stage an inguinal lymphadenectomy was not performed as a rule.

[Retrograde ejaculation].

Antegrade ejaculation requires intact anatomy and innervation of the bladder neck. Retrograde ejaculation is an uncommon cause of infertility and can be defined as the escape of seminal fluid from the posterior urethra into the bladder. This pathological condition can result from disturbances at the bladder neck due to anatomical lesions, neuropathic disorders or pharmacological influences. Also congenital and idiophatic causes have been described. The diagnosis may be confirmed by findings sperm in post-coital specimens of urine. Pharmacological manipulation, electro-ejaculation and vibro-ejaculation can be utilized to recovery ejaculation. When anterograde ejaculation in this patients cannot be restored artificial insemination using sperm recovered from the antegrade post-coital urine is indicated. The aim of this paper is to evaluate the data of literature on aetiology and therapy of retrograde ejaculation.

[Comparison of the quality of life of patients treated by surgery or radiotherapy in epidermoid cancer of the penis].

OBJECTIVE: The purpose of our work is to examine how partially or totally radical surgery and radiotherapy can weigh on quality of life in patients with squamous carcinoma of the penis, considering whether quality of life can be a good criterion in treatment options. MATERIAL AND METHODS: We have interviewed 17 patients alive and disease-free (average follow-up 69.43 months) after surgical treatment or radiotherapy for cancer of the penis (emasculation, 2; total amputation of the penis, 2; partial penectomy, 11; radiotherapy, 2). Tests used: General Health Questionnaire (G.H.Q.-12 by D. Goldberg); Hospital Anxiety and Depression Scale (H.A.D.S.); Social Problem Questionnaire (S.P.Q.); Overall Sexual Functioning Questionnaire (O.S.F.Q); Family APGAR Questionnaire (F.A.Q.); Performance Status ECOG. RESULTS: Thirty-five per cent of the patients presented limitations in their state of health and social problems. Anxiety was evident in 29.5% of the patients and depression in 6%. The global sexual function was compromised in 76.5%. CONCLUSION: The profile of quality of life resulted compromised in the patients who had undergone radical surgical treatment. The sexual function was the most altered component. The impact of the pathology and its treatment on the other domains of quality of life proved less significant.

[Percutaneous, laparoscopic, and surgical treatment of idiopathic varicocele: analysis of costs].

Idiopathic varicocele can compromise the spermatogenetic function of the testicle and associate with alterations of the semen quality. The treatment of varicocele stops the progress of testicular damage and improves spermatogenesis and semen parameters. These are the main alternatives to the traditional surgical treatment of varicocele retrograde percutaneous occlusion of the internal spermatic vein using sclerosing agents and embolizing devices (either separately or in combination), microsurgical ligation via inguinal or sub-inguinal approach, laparoscopic ligation and, more recently, antegrade scrotal sclerotherapy. None of these techniques can be considered the "gold standard" therapy. Literature does not point out any significant difference between them, either considering the absence of reflux percentage, or the improvement of semen quality, or the pregnance rate. Therefore cost comparison may be a valid criterion in the choice of treatment for varicocele correction. The total cost of the surgical retroperitoneal unilateral ligation of the internal spermatic vein is 968,805 Lire, while for the bilateral ligation it is 1,118,285 Lire. The costs of sclerotherapy and percutaneous embolization are respectively of 698,750 Lire and 1,708,950 Lire. The combination of the two techniques amounts to 1,918,230 Lire. Laparoscopic bilateral ligation costs 2,437,935 Lire. Antegrade scrotal sclerotherapy costs 191,035 Lire if unilateral, 216,580 Lire if bilateral. After considering these data we can say that antegrade scrotal sclerotherapy is the first choice economically in the treatment of both unilateral and bilateral varicocele.

Renal staghorn calculosis: our experience with the percutaneous treatment with or without extracorporeal shock wave lithotripsy.

OBJECTIVES: In this paper we report our results in the treatment of renal staghorn stones by percutaneous lithotripsy (PCNL) with or without extracorporeal shock wave lithotripsy (ESWL). METHODS/RESULTS: Over a period of 5 years, 244 patients with renal calculosis were treated by PCNL in our Department. Seventy-four of these were cases of renal staghorn calculosis: 44 presented a partial staghorn stone and in 30 cases the stone formation completely occupied the pyelocalieal cavity. We performed first a PCNL via a rigid nephroscope. Stones were crushed using an ultrasonic lithotrite; an electrohydraulic probe was used when the calculus was resistant to ultrasound. The patients were submitted to one or more percutaneous treatments followed by extracorporeal lithotripsy to complete the operation, when required. The patients were divided into two groups according to the type of stone: the first group comprised 59 patients with a partial or complete simple staghorn stone and the second comprised 15 patients with a complete complex staghorn stone. Complete resolution was achieved in 55 of the 59 cases (93.2%) in the first group and in 9 of the 15 cases (60%) in the second. We had no complications. CONCLUSIONS: Our experience confirms that PCNL is the elective treatment for partial and complete staghorn stones and ESWL in these types of stones must be utilized only as ancillary treatment for residual fragments.

[Our experience in the conservative surgical treatment of megaureter in the adult].

Surgical treatment of the megaureter in adults is only indicated when important symptoms and/or complications occur. The Authors report their experience with eight adult patients affected by megaureter, undergone to conservative surgery. The average age of the patients was 36 years (range 21-52). The disease was unilateral in five cases (four on the right side and one on the left), bilateral in three. In five patients megaureter was primary (obstructed in four, refluxing in one). A case of megaureter with ectopic orifice in the prostatic urethra was observed. The remaining two cases, already operated in other hospitals, were a segmentary megaureter associated with vesico-ureteral reflux secondary to endoscopic incision of an ureterocele and a bilateral refluxing megaureter in a patient undergone to bilateral ureterocystoneostomy because of primary megaureter in his childhood. All patients underwent ureterocystoneostomy, performed with Politano-Leadbetter antireflux technique in six cases and with direct non-antireflux technique in two. A reductive Hendren ureteroplasty was also performed in 7 cases. The average length of follow-up is actually of 82 months (range 5-231). Satisfactory results were obtained in three primary obstructed megaureters, in the megaureter with ectopic orifice and in the segmentary megaureter associated with reflux. In two patients with refluxing megaureter surgery was unsuccessful and a new operation was necessary. Finally, one patient with primary obstructed megaureter underwent endoscopic dilatation of the strictured vesico-ureteral anastomosis two months after the ureterocystoneostomy.
