[Migration of an intrauterine device into the bladder. Report of a case].

PURPOSE: We report an uncommon case of a bladder lithiasis arising from an intrauterine device (i.u.d.). CASE REPORT: A female patient with i.u.d. for 13 years consulted for frequent episodes of cystitis. Patient evaluation demonstrated a bladder stone. RESULTS: Treatment was cystolithotomy, which dislodged two stones. One stone was attached to the IUD. CONCLUSION: Bladder calculus arising from an IUD is very rare. We review the literature.

A French national epidemiologic survey on renal cell carcinoma. Oncology Committee of the Association Française d'Urologie.

BACKGROUND: In this multicenter study, the yearly national evaluation of tumors of the kidney was out by the Oncology Committee of the French Association of Urology. METHODS: During the period from April 1, 1992, to March 31, 1994, 1486 patients from 54 centers were included in this study. For each patient, an individual chart was created, in which age, gender, discovery circumstances of the tumor, radiologic and biologic workup, treatment, TNM classification, and histologic features of the tumor were recorded. RESULTS: The mean patient age was 62.1 years, and the male-to-female ratio was 2:1. Forty percent of the tumors were discovered accidentally. A radical nephrectomy was performed in 93% of the cases, and in 7% of the cases, conservative management was adopted. Medical treatment was chosen in 5% of the cases. The patient distribution according to classification was as follows: pT1 = 8%, pT2 = 53%, pT3a = 21%, and pT3b = 18%. Lymph node involvement was observed in 9% and visceral metastasis in 6% of the cases. The incidental tumors were intracapsular in 80% of the cases. From the histologic point of view, the majority of the tumors were clear cell adenocarcinoma (66%). The mean tumor maximum dimension was 6.4 +/- 3.5 cm; it was significantly greater in symptomatic patients and patients with poor prognostic indicators (involvement of the adrenal gland, inferior vena cava, and/or lymph nodes and visceral metastasis). Adrenal gland involvement or inferior vena cava involvement were each observed in 4% of the cases. Fourteen percent of the patients had multicentric tumor spread, which was influenced by neither the tumor size nor the cell type. The nuclear grade was established in 66% of the cases and was significantly correlated with involvement of the perirenal fat and the lymph nodes. CONCLUSIONS: This study allowed the authors to centralize one-fifth of all new cases of adenocarcinoma of the kidney in France in the course of a year. It enabled them to evaluate precisely the current epidemiologic profile of this disease among those patients.

Laparoscopic adrenalectomy: the retroperitoneal approach.

PURPOSE: Retroperitoneal laparoscopy, by providing direct access to the retroperitoneal cavity, is an interesting approach to urological surgery. We report our initial experience with retroperitoneal laparoscopic adrenalectomy. MATERIALS AND METHODS: Between January 1995 and April 1997, 23 adrenalectomies were performed by retroperitoneal laparoscopy in 10 men and 12 women. The patients were placed in the lateral decubitus position and 5 trocars were used. The retroperitoneal working space was created by digital dissection and was completed by insufflation without balloon dissection. The surgical indications were Conn's adenoma in 12 cases, Cushing's adenoma in 4, bilateral adrenal hyperplasia (Cushing's disease) in 1 (treated in a single procedure), a nonfunctioning adenoma in 2, pheochromocytoma in 2 and adrenal metastasis in 1. RESULTS: We removed 7 right and 16 left adrenal glands in an average operating time of 97 minutes (range 45 to 160). Average tumor size was 26 mm. (range 10 to 40). Average hospital stay was 3.3 days (range 1 to 10). Blood loss was minimal. Postoperative analgesic requirements were moderate. Conversion to open surgery was not necessary. The morbidity rate was low, with 1 postoperative hematoma and 1 case of persistent fever (greater than 38.5C). CONCLUSIONS: Retroperitoneal adrenalectomy is a reliable and effective technique. At our institution retroperitoneal laparoscopy is now the standard adrenal surgery procedure for tumors less than 5 cm.

Adenoma

Unusual case of Munchausen's syndrome: factitious vesical lithiasis.

We report an uncommon case of a 38-year-old woman who admitted for bladder lithiasis undergoing repeated surgical management and being apparently recurrent. The intravenous pyelography and retrograde urethrocystography clear the urinary tract. Biologic evaluation eliminates any metabolic or endocrine cause. The confirmation of a factitious origin is given by fluorescence X analysis of the extracted stones which conclude to calcium carbonate structure and psychiatric care. The self-intromission of these calculi into the bladder is due to the personality disorder being in the frame of Munchausen's syndrome. Two years later, no recurrence is noted and an excellent psychiatric care is achieved.

[Rigid ureteroscopy. Apropos of 88 cases].

Rigid ureteroscopy has become a common tool for the diagnosis and management of several diseases of the upper urinary tract. Between April 1990 and April 1996, 92 ureteroscopy procedures were performed in 88 patients in the B Urology Department of Avicennes hospital for diagnostic or therapeutic purposes. The commonest therapeutic procedure was stone manipulation (72 cases). The overall success rate was 90.8% (Distal ureter: 89.6%, mid ureter: 80%, lumbar ureter: 100%) and the complication rate was 4%. Therapeutic ureteroscopy was also used to dry ureterovaginal fistula (4 cases) and ureteral fistula with retroperitoneal urinoma (2 cases), and to remove a double J stent which had migrated into the pelvic ureter (3 cases). Diagnostic ureteroscopy was performed for 7 ureteral strictures including 3 extrinsic compressions and 4 ureteral strictures all treated with dilatations after biopsy. One false passage was observed among diagnostic ureteroscopy procedures. Rigid ureteroscopy is a minimally invasive and reliable technique for the management of ureteric calculi and for the diagnosis and treatment of other ureteric lesions.

[Fractures of the penis: apropos of 56 cases].

OBJECTIVES: To review the diagnostic and epidemiological aspects and especially to demonstrate the value of emergency surgical treatment. PATIENTS AND METHODS: In 8 years (1989-1996), 56 fractures of the penis in 55 patients were surgically repaired as an emergency procedure immediately after admission. The skin incision was often elective and longitudinal. After evacuation of the haematoma, the fracture was sutured with slowly resorbed suture material. The presence of a concomitant urethral lesion was systematically investigated and repaired. RESULTS: The mean age was 30 years, and 72.75% of patients were unmarried men. The mean operating time was 40 min and the mean hospital stay was 1.5 days. The immediate postoperative course was always favourable. In 36 long-term evaluable patients, sexual activity was resumed with no difficulties of erection or intromission. No case of chordee of the penis was observed, but two patients presented a cicatricial nodule. CONCLUSION: Fracture of the penis is a rare disease and is diagnosed clinically. Emergency surgical treatment is the only guarantee of a good functional prognosis.

[The VLAP system (Visual Laser Ablation of the Prostate): comparative study of the contact versus non-contact techniques in a series of 100 cases].

OBJECTIVE: To compare two contact and non-contact techniques using the VLAP system (visual laser ablation of the prostate). PATIENTS AND METHOD: From January 1994 to April 1995, two groups of 50 patients were included in a randomized prospective study and were treated by the contact and non-contact laser technique, respectively. These patients presented with symptomatic BPH requiring transurethral electroresection. These patients were evaluated according to subjective (AUA score) and objective criteria (maximum flow rate, transrectal and suprapubic ultrasonography). ND:YAG laser energy was delivered by a Medilas 4100 source via a lateral beam fibre. Objective success criteria were an improvement of the AUA score by at least 50% and of the maximum flow rate by at least 50% with a difference of 4 mL/s. The failure criterion was the need to perform complementary electroresection during the first 6 postoperative months. RESULTS: The mortality was 2% (cardiovascular causes), and the overall morbidity (first postoperative month) was 29%, with 21% of a vesical irritation syndrome, 6% of urinary tract infection and 2% of bladder clots. The global result at 12 months showed a statistically significant postoperative improvement of the subjective and objective parameters studied preoperatively (p = 0.0001). In the contact group, the AUA score, mean maximum flow rate and residual urine, which had preoperative values of 19.1, 9.1 mL/s and 141 mL, respectively, were equal to 2.3, 15.6 mL/s and 45 mL at 12 months. In the non-contact group, the same parameters, which had preoperative values of 17.8, 9.2 mL/s and 87 mL, respectively, were equal to 3.8, 13.3 mL/s and 47 mL at 12 months. The results, evaluated as a function of objective success criteria, showed a 12-month success rate of 68% for the contact method and 61% for the non-contact method. The mean hospital stay was 6 days and the mean duration of bladder catheterization was 5 days with the two techniques. During follow-up, 7% of patients required revision by electroresection, regardless of the technique used. CONCLUSION: this study demonstrated identical results for the contact and non-contact techniques using the VLAP system.

[Malignant histiocytofibroma of the bladder. A case report].

Malignant histiocytofibroma of the bladder is a rare (16 cases reported in the literature) and very aggressive sarcoma. It is sometimes associated with a haematological malignancy. The authors report a case of malignant histiocytofibroma of the bladder in a 72-year-old haemodialysed woman with a poor general status. She had a history of chemotherapy and radiotherapy for gastrointestinal lymphoma 6 years previously. Treatment consisted of palliative cystectomy for bladder pain and haematuria. A massive pelvic and abdominal wall recurrence occurred two months after cystectomy and the patient died. The authors review the 16 cases of malignant histiocytofibroma of the bladder reported in the literature. Histiocytofibroma is a tumour which requires aggressive treatment with a combination of radical surgery and systemic chemotherapy.

[An unusual complication of anterograde endopyelotomy: ureteral intussusception (a case report)].

Endopyelotomy has recently found a new place in the treatment of stenosis of the pyeloureteral junction, and it can represent a treatment of choice. We report an unusual case of antegrade ureteral intussusception after antegrade endopyelotomy in a 30 year-old young woman with a solitary kidney, which caused proximal ureteral obstruction. These intussusceptions were probably caused by double CH endoprosthesis. These iatrogenic injuries required surgical resection with calicoureterostomy.

[Infiltrating bladder tumor in a renal transplant patient: cystectomy with prostatic conservation and enterocystoplasty].

OBJECTIVE: The principles of treatment of de novo bladder tumours in renal transplant patients are comparable to those applied in non-transplant patients. In the case of an invasive tumour, techniques can be used to restore urinary tract continuity after cystectomy. A case of cystectomy with enterocystoplasty for invasive bladder tumour in a renal transplant patient is reported. MATERIAL AND METHODS: An invasive urothelial bladder tumour was discovered in a 62-year-old man, 3 months after a 2nd renal transplantation. Treatment consisted of cystectomy with prostatic preservation and nontubulized enterocystoplasty. RESULT: With a follow-up of 21 months after cystectomy, the patient is alive without recurrence. He is perfectly continent during the day, with normal sexual intercourse and no reflux or residual urine. Renal function is normal. CONCLUSION: Cystectomy with enterocystoplasty can be an effective treatment for invasive bladder tumour in renal transplant patients. This treatment ensures oncological control and acceptable comfort while preserving the transplant.

[Adenocarcinoma of the kidney associated with polycystic kidney treated by conservative surgery (apropos of a case)].

The authors report a case of renal cell carcinoma discovered incidentally in a 52-year-old woman with hepatorenal and pancreatic polycystic disease. Treatment consisted of partial nephrectomy with no adjuvant therapy. After a 3-year follow-up, the patient is still alive with normal renal function and no signs of recurrence. The pathogenesis and therapeutic modalities are discussed in the light of a review of the literature.

[Acucise endoureterotomy for distal ureteral stenosis in a renal transplant patient].

The treatment of ureteric strictures in renal transplantation used to be surgical, but has recently benefited from progress in endourology. The authors report the case of a renal transplant recipient who developed late stricture of the ureterovesical reimplantation of the transplant. After percutaneous nephrostomy, which restored good renal function, retrograde endoureterotomy was performed using an Acucise ureterotome balloon, followed by ureteric modelling on a 7F double J stent for 2 months. With a follow-up of 18 months, renal function was normal and ultrasonography showed residual hypotonia of the transplant cavities and no vesicorenal reflux was detected by retrograde voiding cystourethrography. Acucise retrograde endoureterotomy can constitute a simple endourological treatment for late ureteric strictures in renal transplantation.

[Ureter injuries: therapeutic approach and the role of ureteroscopy. Apropos of 18 cases].

From June 1990 to June 1996, 18 patients with ureteric injuries were treated in our institution. All ureteric lesions were diagnosed post-operatively and repaired early (2 cases) or after a delay (16 cases). 4 patients underwent exclusive endourological treatment, 10 patients underwent repair by open surgery without preliminary endourological procedure, and in the remaining 4 patients, the two methods were combined. In this group, ureteroscopy, which facilitates intraoperative identification of the ureteric segment below the lesion, allowed end-to-end ureteric anastomosis, which, in the light of our results, constitutes the reference surgical technique.

[Contralateral perirenal metastasis of renal adenocarcinoma].

The objective of this paper is to report an exceptional case of solitary contralateral perirenal metastasis from a renal cell carcinoma. Investigation of this 62-year old patient, presenting with isolated haematuria, revealed a tumour, 9 cm in diameter, in the upper pole of the right kidney, associated with contralateral metastasis in the left perirenal fat. A right radical nephrectomy and left lumpectomy including the fat around the tumour were performed via a bilateral subcostal incision. Pathological staging was pT3b N0 M1, Fuhrman grade III. With a follow-up of eight months, this patient was asymptomatic with a normal radiological assessment.

Adenocarcinoma

[Hemospermia].

Haemospermia is a relatively frequent symptom in urology, especially in young subjects. It is often benign, but is important because of the anxiety it can cause to the patient. The predominant aetiology of haemospermia is prostatic and seminal vesicle disease. Iatrogenic aetiologies, generally without severity, are due to the development of instrumental diagnosis and treatment in urology. Recent progress in the field of medical imaging, particularly transrectal ultrasonography and magnetic resonance imaging, has greatly contributed to the diagnostic and therapeutic approach to haemospermia.

[The AMS 800 sphincter in urinary incontinence after prostatic surgery. Apropos of 16 patients].

OBJECTIVE: To present the results of a series of artificial sphincters implanted for urinary incontinence after prostatic surgery. PATIENTS AND METHODS: From 1987 to 1996, artificial sphincters were implanted for urinary incontinence after prostatic surgery, consisting of one transvesical prostatectomy, 11 prostatic resections and 4 radical prostatectomies. All these patients were evaluate by urine culture, cystourethrography and urethrocystoscopy. Eleven patients underwent urodynamic assessment. The AMS 800 artificial sphincter was used. RESULTS: The mean interval between onset of incontinence and implantation was 18 months. The mean follow-up after implantation of the sphincter was 6 years. An operative wound of the bulbar urethra did not prevent implantation of the sphincter, but required repair and prolonged catheterization (12 days). The mean duration of catheterization was 6 days. The overall functional result was 81% (13 case), and 75% of sphincters were functional at 5 years. Five revisions were necessary to maintain functioning of the sphincter in 2 cases of rupture and 1 displacement of the balloon, 1 case of urethral atrophy and 1 rupture of the pump. Three explanations, 2 total and 1 partial, were performed. Two reimplantations were performed after 12 months and 26 months respectively. CONCLUSION: The AMS 800 artificial sphincter currently represents an effective treatment for urinary incontinence due to sphincter insufficiency after prostatic surgery. However, an old artificial sphincter may require revision to restore function.
