[Percutaneous nephrostomy: indications, techniques and results. Retrospective study of 81 cases].

A retrospective study has been made of 81 cases of percutaneous nephrostomy (PCN) which were treated during the period 1989-1998. The mean patient age was 41 years (age range: 21-66 years). The reasons for the diversion via nephrostomy catheter were oligoanuria (43 cases), pyonephrosis (34 cases), and evaluation of renal function (four cases). The initial disease was found to be malignant in 23.25% of cases of oligoanuria, with six cancers of the cervix, three bladder cancers and one prostate cancer. Lithiasis was the main etiology in subjects with benign disease, and was the causative factor of oligoanuria in 55.8% and pyonephrosis in 67.6% of cases, i.e., a total of 47 cases (58%). PCN catheter placement was successfully carried out in 100% of cases, and resulted in improved renal function, and/or in the treatment of the initial infectious syndrome in the majority of cases. PCN is an excellent technique for upper urinary tract drainage due to its simplicity, efficacy, ease of insertion, low cost and satisfactory results. It is a minimally invasive technique, which necessitates only the use of a local anesthetic, a sound knowledge of the human anatomy involved, a trained operator and a minimum of material.

[Our results with percutaneous nephrolithotomy. Report of 61 cases].

Between January 1990 and December 1997, 61 patients with renal calculi underwent percutaneous nepholithotomy. In the immediate postoperative period, 49 renal units (80.3%) were stone-free. At three months, our overall success rate was 91.8% after spontaneous elimination of non-significant residual calculi (< 3 mm). Complications were observed in 9.8% (six cases); hemorrhage and sepsis were the major complications. Percutaneous nephrolithotomy is an effective, safe and reliable alternative to the open operation.

[Vesico-uterine fistula. Report of 10 cases].

OBJECTIVE: To study the aetiopathogenics, diagnostic and therapeutic aspects of this pathology. MATERIALS AND METHODS: The authors report a series of 10 vesico-uterine fistulas observed over à 10 years period. The mean age was 32 years(30-40). The fistulas were secondary to cesarian section in 6 cases and to abnormal delivery in 4 cases. The symptomatology was an urinary leakage from the vagina in 6 cases, an isolated cyclic hematuria in 3 cases and the association of the two signs in one case. The diagnostic was established on clinical examination in 8 cases. Intraveinous urography was performed in all the patients and visualised the uterine cavity in only 8 cases. In the 2 remaining cases a retrograd cystography was performed and demonstrated the opacification of the uterine cavity. The treatment was surgical in 9 cases. One patient who had a menuria has refused the operation. RESULTS: The diagnostic of the vesico-uterine fistulas is often based on clinic examination but often necessitate recourse to complementary examinations mostly in the menouria forms. The intraveinous urography does not establish the diagnostic in all the cases but is an indispensable complementary investigation because it permits searching for an associated ureteral injury. With a mean recoil of one year the results judged on the disappearance of the clinic signs was good in all the patients. CONCLUSION: The vesico-uterine fistulas are often secondary to cesarian section or abnormal delivery. Their treatment is surgical but is above all preventive by the improvement of the obstetric taking care and avoiding the vesical injuries in the course of the cesarian section.

[Cancer of the female urethra. Report of 2 new cases].

Female urethral cancer is a rare urologic malignancy, it is about 0.02% of genito urinary cancer in woman. Prognosis remains poor and it depends of staging of disease. Applying combined modality treatment (radiation and surgery) may produce local control and increase the survival.

[Microsurgical epididymal sperm aspiration (MESA), testicular biopsy and intracytoplasmic sperm injection (ICSI) in the treatment of male infertility].

OBJECTIVE: To assess if ICSI using epididymal or testicular spermatozoa is effective in the treatment of couples with male factor infertility. MATERIAL AND METHODS: 56 couples suffering from male infertility underwent a total of 88 treatment cycles of ICSI, in combination with microsurgical epididymal sperm aspiration (MESA): 62 cycles, or testicular sperm retrieval: 26 cycles. RESULTS: Overall, fertilization rate was 63% per injected metaphase II oocyte. In MESA group, fertilization rate was 64% compared to 61% embryos in testicular sperm aspiration. The overall pregnancy rate was 26% per started ICSI cycle. Pregnancy rates were also similar in both group: 24% for MESA and 32% for testicular sperm extraction. 9 pregnancy (41%) were obtained using cryopreserved epididymal sperm (6 cases) or testicular sperm (3 cases). CONCLUSION: ICSI combined with epididymal or testicular sperm achieved a high fertilization and pregnancy rate. It constitutes an efficient alternative in the treatment of men suffering of testicular failure or azoospermia not amenable to surgical reconstruction.

[Percutaneous endopyelotomy. Apropos of 27 cases].

27 percutaneous endopyélotomies were performed in 27 patients from February 1989 to January 1996 to treat 20 cases of congenital hydronephrosis and 7 cases of acquired stenosis. Strictures of uretero-pelvic junction were treated by electrocautery with postoperative drainage using a double J stent in 11 cases, or Redon drain in 16 cases. The evaluable results for 25 patients with a mean follow-up of 11 months showed an overall success rate of 80%. This technique is the treatment of choice for acquired stenosis and stage I and II congenital hydronephrosis (Cendron).

[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.

[Urogenital tuberculosis. Apropos of 40 cases].

The authors report a series of 40 cases of genitourinary tuberculosis diagnosed and treated in the department of urology "B" of Avicenne hospital over a 7-year period. The objective of this study is to define the various diagnostic and therapeutic aspects of this disease. The patients were predominantly males (62.5%) with a mean age of 40 years. 25% of cases reported a history of extra-urinary tuberculosis. The very polymorphous clinical presentation is dominated by signs of cystitis (45%). Intravenous urography is frequently suggestive of the diagnosis based on the appearance and multiplicity of the lesions. The radiological lesions most frequently encountered were silent kidney (19 cases) and small tuberculous bladder (11 cases). The definitive diagnosis was established by pathological examination in 38 cases (biopsies, operative specimens, prostatic resection chips) and/or by demonstration of AFB in 2 cases (urine, pus). Tuberculostatic treatment was administered to all patients, either alone (5 cases) or, more usually, in combination with surgical and/or endo-urological treatment (35 cases), reflecting the magnitude and severity of the destructive and scar lesions.

Ureteroileal fistula: an unusual complication of Crohn's disease.

We report a case of urteroileal fistula in a young 22 year-old-man with Crohn's disease, who presented with microscopic hematuria and severe diarrhea. Excretory urogram and retrograde pyelography showed a fistula between the right ureter and the terminal ileum which was successfully managed with conservative approach using a double J ureteral stent.
