[A case of renocolic fistula complicating xanthogranulomatous pyelonephritis treated by laparoscopy].

The authors report a case of xanthogranulomatous pyelonephritis complicated by renocolic fistula. This is a rare complication. The patient was treated by right nephrectomy and closure of the fistula performed by manually assisted laparoscopic surgery.

[Transcaval ureter].

The authors report a case of transcaval ureter complicated by acute obstructive pyelonephritis in a 54-year-old patient. Transcaval ureter is a rare congenital malformation of the infra-renal inferior vena cava (IRIVC) in which the right ureter passes through a venous ring composed of localized duplication of the vena cava due to persistence of the right posterior cardinal and supracardinal veins.

[Sarcomatoid carcinoma of the bladder with major osseous metaplasia].

The authors describe a case of sarcomatoid carcinoma of the bladder, in which the stroma presented marked calcified bone metaplasia. Mechanical lithotripsy of the tumor was necessary to allow transurethral resection.

[Kidney varices: an unusual location].

The authors report the case of a 40-year-old woman who presented with very large right renal varices. Computed tomography and arteriography showed that these varices were situated on the convex surface of the kidney, in front of its anterior surface, and drained venous blood derived from the renal parenchyma. These varices were probably secondary to undiagnosed renal vein thrombosis.

[Reduction of the weight of prostatic tissue during transurethral resection].

Objective: To study the weight reduction of prostatic tissue removed during transurethral resection.

Method: 22 hyperplastic prostate glands enucleated via a transvesical approach were resected in vitro, under conditions as close as possible to in vivo resection in 11 cases. The authors compared the weight of the enucleated prostates with the weight of fresh resection chips and the weight of chips fixed in Bouin solution.

[Pseudotumoral xanthogranulomatous pyelonephritis. A propos of 2 cases].

We report two cases of xanthogranulomatous pyelonephritis observed in elderly women. Diagnosis before surgery is difficult. CT is the best single examination.

[Emphysematous pyelonephritis. A case medically treated].

Authors report on a case of emphysematous pyelonephritis in a woman affected with diabetes and renal failure. In order to avoid chronic dialysis, no nephrectomy was performed and the patient was treated only with drugs. Full recovery was obtained, without worsening of the renal function.

[Ureteral stenosis caused by pelvic actinomycosis].

The authors report a case of pelvic actinomycosis causing ureteral obstruction in a 30-year-old woman. An intra-uterine device being in place for 6 years is considered as the main cause. The treatment, which included a laparotomy for abscess drainage, an indwelling double pigtail ureteral stent and a 9 month antibiotherapy led to recovery after an initial relapse.

[Colonic adenocarcinoma after Coffey's operation. A case].

The authors describe a case of colonic adenocarcinoma in an 41-year-old woman who had undergone at age 3 an uretero-colic anastomosis because of bladder exstrophy. The tumor looked like an ovarian tumor and histology confirmed it was a Krûckenberg tumor of colonic origin. The authors review literature and insist on the necessity of a life long endoscopic follow-up of uretero-colic anastomosis.

[Pseudotumoral thoracic actinomycosis with lung and brain metastases. Apropos of a case. Review of hundred thirty one cases in the literature].

One particular case of thoracic actinomycosis is reported. The patient presented with a neurological picture mimicking a metastasis, as chest radiogram and CT-Scan indicated a primary pulmonary tumor. Diagnosis of actinomycosis was overlooked and final diagnosis was based on direct microscopy of lung tumor, which required a thoracotomy, without any resection.
