[Local recurrence of paratesticular rhabdomyosarcoma]. / Récidive locale d'un rhabdomyosarcome paratesticulaire.

We report an uncommon case of scrotal recurrence of embryonal paratesticular rhabdomyosarcoma in 19 year old man after 3 years later. The diagnosis was suspected clinically and confirmed by histopathology study after resection of the scrotal tumor. About this case, the authors discuss the diagnosis and the management of this tumor.

[Acute renal insufficiency due to hydronephrosis]. / Insuffisance rénale aiguë par hydronéphrose.

Acute renal failure due to hydronephrosis is a rare pathology. It can occur unilaterally, or as a pyelo-ureteral junction (PUJ) bilateral syndrome. In the present study, two cases have been reported. The diagnosis was based on ultrasonographic findings which showed hydronephrosis, and on descending pyelo-ureterography (DPU), which demonstrated an absence of opacification. Infection was present in one case. Preliminary treatment consisted of percutaneous nephrostomy, followed by surgical pyelo-ureteral resection and Anderson-Hynes pyeloplasty which gave good results (95% success rate), and which enabled a satisfactory recovery of renal function to be obtained.

[Percutaneous nephrostomy in emergencies. Report of 42 cases]. / La néphrostomie percutanée en urgence. A propos de 42 cas.

PURPOSE: Through this work we are going to demonstrate the interest and the contribution of the percutaneous nephrostomy in obstructive anuria and in pyonephrosis. PATIENTS AND METHODS: It is a retrospective study concerning 42 cases. The average age of the patients is 50 years (19-80 years). The sex-ratio is 26 men for 16 women. The nephrostomy was realized in first intention or after failure of ascent stent on 33 patients for an obstructive anuria and nine patients for a pyonephrosis. RESULTS: Improvement of the renal function was noted in 100% of obstructive with anuria and apyrexy in every case of pyonephrosis. No major complication arose during the realization of the nephrostomy. The long-term prognostic depends on the etiology. CONCLUSION: The percutaneous nephrostomy constitutes a saving, effective and temporary solution in the strategy of the coverage of obstructive anuria and pyonephrosis.

[Seminal vesicle cyst associated with ipsilateral renal agenesis]. / Le kyste de la vésicule séminale associé à une agénésie rénale ipsilatérale.

UNLABELLED: The seminal vesicle cyst associated with ipsilaterale renal agenesis is a rare entity. Through this case report, we analyse the clinical aspects, the importance of imaging techniques and the various therapeutic possibilities. The patient, age 24, presented perineal pain accentuated at ejaculation. The digital rectal examination showed a pre-rectal lump. Transrectal ultrasound plays an important role both for the diagnosis and the treatment. The treatment was perineal aspiration under transrectal echography control. The follow-up was satisfactory. CONCLUSION: The seminal cyst with ipsilareral renal agenesis is a rare congenital malformation, transrectal ultrasound is an excellent imaging technique for diagnosis, the perineal aspiration of the cyst constitutes a therapeutic alternative.

[Bivalve anatrophic nephrolithotomy]. / La néphrolithotomie bivalve anatrophique.

PURPOSE: In the era of lithotripsy, surgery gets a limited place in the management of renal stones. This study has for a goal to evaluate the practice, indications and results of anatrophic nephrolithotomy in the treatment of staghorn calculi. PATIENTS AND METHODS: Between 1998 and 1999, six patients, mean age 37 years, had complete staghorn calculi treated by anatrophic nephrolithotomy, and two patients had a bilateral lithiasis. After lombar incision, the kidney was incised on the convexity after pedicular control. In this way, we have extracted all lithiases. The nephrorrhaphy permits hemostasis and parenchymal reparation. A ureteral stent was placed. RESULTS: The operatory follow-up was simple; hemostasis was controlled by fast extraction of the lithiasis and nephrorrhaphy. The operating time was 70 minutes (40-110). The stone free rate was 100% without alteration of renal function, patients with bilateral lithiasis have been operated twice time. CONCLUSION: The anatrophic nephrolithotomy is a safe technic without risk of haemorrhage or renal function alteration.

[Torsion of an undescended testis. Apropos of a case]. / Torsion du testicule non descendu. A propos d'un cas.

The authors report an uncommon case of torsion of an inguinal undescended testis occurring in a 15-year-old child. He consulted seven days later for isolated left inguinal pain. Physical examination showed a left inguinal mass, and only the right testis was palpable within the scrotum. Sonography revealed left inguinal mass with echogenic and heterogeneous contents in keeping with undescended testis. The diagnoses of testis tumor or testis torsion were suggested. Surgical exploration revealed a mass suggesting a testis tumor. Orchidectomy was performed. Histological examination showed that the mass corresponded to a necrotic ischemic testis without tumor cells. In the light of this case, the authors analyse the diagnostic aspects and management of torsion of an undescended testis.
