[The treatment of ureteroceles complicated by calculi].

In a series of 13 adults with calculi in ureteroceles, 10 cases underwent endoscopic meatotomy associated with endoscopic lithotripsy. In 2 bulky ureteroceles with calculi, the authors performed excision of the ureterocele and reimplantation of the ureter. In one case, the authors successfully performed extracorporeal lithotripsy. The authors obtained good results in all cases. Endoscopic meatotomy with lithotripsy is a very useful procedure for treatment of small or medium sized ureteroceles with calculi in adults.

[Renal tuberculosis with pseudotumoral form: apropos of a case].

The authors report about one rare case of renal tuberculosis in a pseudo-tumoral form, which had radiologic appearances compatible with a kidney cancer invading soft tissue. The fast spontaneous evolution towards fistulization allowed confirming the diagnosis of urinary tuberculosis. The outcome with treatment was favorable. The authors recommend that needle biopsy should be made in cases of doubtful kidney tumors to provide an exact diagnosis.

[Retrocaval ureter. Apropos of 6 cases].

The authors report six cases of retrocaval ureter discovered in quite various circumstances. A genital malformation associated to the retrocaval ureter was found in only one case. Five of our six patients were operated. Four of them underwent uncrossing of the ureter relative to the vena cava, and a patient underwent nephrectomy because her kidney was destroyed. The sixth patient was not operated because there was no impact on the excretory cavities of the kidney. This series and the review of the literature allow specifying the course of action for this pathology.

[Retrovesical hydatid cyst. Apropos of 2 cases].

A hypogastric mass compressing the bladder in an adult, in a zone endemic for hydatid disease, should raise to suspicion of a retrovesical cyst, especially as the cyst sometimes opens into the bladder resulting in haematuria and hydatiduria. Intravenous urography and ultrasonography facilitate the topographical diagnosis. Treatment is surgical: transperitoneal cystectomy and pericystic resection as extensive as possible with exploration of the abdomen looking for other sites (liver, mesentery, omentum). This treatment was successful in the two cases reported here. In conclusion, a stable cure can be obtained by adopting a well defined therapeutic approach to these rare lesions.

[The valves of the ureter. Apropos of 2 cases].

The authors report two cases of congenital ureteral valves of the upper third of the ureter complicated by renal stone in two children and diagnosed by I.V.P. The two patients underwent a resection of the pathological segment and a pelvic-ureteral anastomosis successfully. The review of the literature data regarding ureteral valves allowed to emphasize the uncommon of the bilateral form complicated by renal stone and the better preoperative diagnosis by ureteroscopy and antegrade pyelogram.

[Cancer of the urachus].

We report a case of mucin-producing adenocarcinoma of the urachus. Preoperative diagnosis was established by computerized axial tomography. An en bloc resection was performed, including the urachus with supravesical mass and bladder dome.

[Calcified necrosing cystitis].

Calcified necrotising cystitis is an urological curiosity, the authors report two cases. With subsidence of the acute process, regeneration and fibrosis take place, with contracture of the bladder and reduction of its capacity. Augmentation ileocystoplasty was performed with success in one case. The clinical and therapeutic aspects of this rare disease are discussed.

[Fistulas and ureteral strictures after kidney transplantation. Diagnosis and treatment].

We report our experience of 4 urine fistulas and 4 ureteral strictures after renal transplantation. Percutaneous nephrostomy was performed on all patients. The diagnosis was established by antegrade pyelography. Nephrectomy was performed on 2 patients because of failure of drainage and formation of an infected urine collection due to an extended ureteral necrosis. Abstention was elected in one case as renal function did not improve due to associated chronic rejection. In 5 cases, renal function quickly improved with drainage: 2 were operated on immediately, and one after failure of endo-urological treatment of a urine fistula. Antegrade dilatation has been used successfully in one stenosis. In the last case, a double pigtail stent allowed a urine fistula to close. Percutaneous nephrostomy seems to be best method of drainage when ureteral obstruction or fistula is suspected in renal transplant patients, and permits diagnosis by antegrade pyelography. Percutaneous management may be a satisfactory way of treatment for limited stenosis or fistulas.

[Tumors of the bladder in patients under 40 years of age].

It is often stated that younger patients have a better prognosis than their older counterparts. From the records of 17 men and 2 women, aged 40 years or less it appears that bladder carcinoma in patients 30 years-old or less have a favorable prognosis. Disease occurring at age 30 to 40 has a much worse prognosis and is no different from that affecting the older age groups.

[T1 bladder tumors. Can they be considered superficial?].

The authors report about a series of 60 cases of superficial (Ta and T1) bladder tumors and study their evolution towards infiltration according to the grade, size and number. 16% of the T1 tumors evolved towards infiltration and/or metastatic spread after a period of 42 months. In our opinion, T1 tumors can be regarded as superficial tumors. However, our therapeutic attitude is cautious because of pejorative factors of prognosis: high grade, multiple foci, and size exceeding 5 cm.

[Results of detubulate enterocystoplasty. Apropos of 17 cases].

From January 1988 to October 1989, 17 patients underwent radical cystectomy for bladder cancer. They had a bladder replacement by Hautmann pouch. Good results were obtained after a period of observation of 6 to 24 months. Two patients died. Hyperchloremic acidosis was observed in 20% cases. The urinary continence was achieved in 13 patients who were willing to wake up twice every night. One patient preferred the collecting device. Our study showed that the Hautmann pouch is a particular low pressure reservoir with a capacity of 200 ml to 800 ml, and assessed the mechanism of loss of urine at night in one case. The urinary continence was achieved after a good training period and depended on patient's cooperation. This technique permitted to obtain a very satisfactory diurnal and nocturnal continence in our patients, however a longer follow up is mandatory to confirm the efficiency of this method on long term basis.

[The first thirty months of kidney transplantation in Tunisia].

Kidney transplantation is actually the best replacement therapy for the end stage renal failure. It sets free the hemodialysed patient from the hemodialysis restraint and contributes to solve the socio-economic problems risen by chronic hemodialysis. The authors report the results of this technic during the first 30 months of kidney transplantation in the "Hôpital Charles Nicolle" of Tunis. They describe the first steps which led to kidney transplantation, the therapeutic regimens, the medico-legal problems and the specific complications observed during this start period.

[Renal ectopic pheochromocytoma. A case report].

The authors report the case of an ectopic pheochromocytoma without any clinical symptoms or laboratory signs which simulated a renal tumor during clinical and complementary investigations. The diagnosis was established by histology. The ectopic pheochromocytoma and the diagnostic problems of silent tumors are discussed.

[Comparative study of tubulate enterocystoplasty and low pressure bladder. Apropos of 20 cases].

The goal of this presentation is to report the results on morbidity and continence of 20 consecutive patients who, from January 1985 to December 1988, underwent bladder reconstruction after cystectomy for bladder cancer. In ten cases the neo-bladder was a classic ileocystoplasty and in the ten others it was a "low pressure neo-bladder". We compared the two groups although they were not randomized. There was no stadification difference in tumors nor in clinical status. The clinical results were described. There have been four temporary urinary fistulas in the group of low pressure bladder (LPB), and four in the group of classic ileocystoplasty (CI). In the group of LPB, 7 from 8 patients were completely dry day and night and voided every two for three hours while among the 9 patients with CI, 4 were continent day and night.
