Sigmoid perforation, an exceptional late complication of peritoneal prosthesis for treatment of inguinal hernia.

Two cases of sigmoid perforation and fistula occurred as late complications after insertion of a nonresorbable prosthesis by the open preperitoneal inguinal route. These infrequent complications are favoured by peritoneal defects and use of materials which can cause extensive sclerous reactions. Indications for this type of mesh are increasingly common with the intraperitoneal laparoscopic approach, so that careful peritoneal dissection and closure are required.

[Testicular tumor in renal and pancreatic transplantation]. / Tumeur du testicule en transplantation rénale et pancréatique.

The authors report the case of a 49-year-old, insulin-dependent diabetic man treated by double kidney-pancreas transplantation. A T3, N3, M0 testicular tumour was discovered at the 8th month and treated by inguinal orchidectomy and 2 courses of chemotherapy. Immunosuppressant treatment was decreased without any consequences for the transplants. Seven years later, the patient was cured but still treated by haemodialysis for chronic rejection of the renal transplant. The pancreatic transplant was still functional and the patient is waiting for a second renal transplantation.

[Skin graft urethroplasty]. / Urétroplastie par greffe cutanée.

OBJECTIVES: To evaluate the results of skin graft urethroplasty (SGU) in the management of urethral stricture. MATERIAL AND METHODS: Twenty eight patients, with a mean age of 54 years, treated by SGU were reviewed with a mean follow-up of 24.5 months (range: 1-66). The first-line material skin graft material was the foreskin or, in its absence, the penile skin or skin of the arm was used. RESULTS: This study demonstrated a satisfactory result (no clinical signs, maximum flow rate > or = 15 ml/s, no need for salvage surgery) in 67.9% of cases. Although the early complication rate was low, 8 stenoses were observed during subsequent follow-up; 3 of which required open surgical revision. The other relapses were treated by internal urethrotomy or hetero- or autodilatations. This study showed that urine sterility at the time of surgery was a decisive factor. CONCLUSION: The preferential indication for this type of urethroplasty remains a bulbar urethral stricture with sterile urine. However, the aetiology and length of the stricture are not discriminant factors.

[Substitutive non-modeled uretero-ileoplasty]. / Urétéro-iléoplastie non modelée de substitution.

OBJECTIVES: To evaluate the indications and results of replacement uretero-ileoplasties performed over the last six years. MATERIAL AND METHODS: Over a period of 6 years, 8 patients underwent subtotal or total replacement uretero-ileoplasty involving a total of 9 renal units. Preoperative temporary urinary diversion was performed in each patient. The mean preoperative serum creatinine was 88 mumol/l (range: 53 to 150). Uretero-ileoplasty was performed for ureteric stricture in 7 cases (bilateral in one case and in a solitary kidney in one case), ureteric necrosis following renal transplantation without a donor ureter in one case and urothelial tumour on a solitary kidney in one case. RESULTS: The mean follow-up was 54 months. The mean operating time was 218 minutes for uretero-unilateral ileoplasties, with a mean length of hospital stay of 12 days (range: 10 to 18 days). The following complications were observed: acute urinary retention, stenosis of the ileo-vesical implantation treated by endoscopic dilatation, 2 incisional hernias after midline laparotomy, one case of stones of the ileo-vesical anastomosis, non-febrile urinary tract infections treated on an outpatient basis. The functional result was considered to be satisfactory in every case. No electrolyte disorders were observed. Mean postoperative serum creatinine was 86 mumol/l (range: 59 to 140). CONCLUSION: In this recent series with a mean follow-up of 4.5 years, replacement uretero-ileoplasty successfully treated partial or total complex ureteric lesions with a low morbidity.

[Wermer syndrome associated with a bilateral renal tumor]. / Syndrome de Wermer associé à une tumeur rénale bilatérale.

Wermer's syndrome is a polyendocrinopathy characterized by neoplasia of the parathyroidis, pancreas and the pituitary. We report a case, unique in our knowledge, of an unusual association of a bilateral renal tumors and Wermer's syndrome. The originality of this case is: Bilateral renal blow. Therapeutic difficulties. This manifestation may represent a new manifestation of this pleiotropic syndrome.

[Lumbar pain and hydrocalyx]. / Douleurs lombaires et hydrocalice.

The authors report the case of a patient presenting with disabling left lumbar pain. Complementary investigations confirmed the diagnosis of isolated hydrocalyx with no organic cause. Surgical treatment was conservative with caliceal plasty. The authors discuss the diagnostic and therapeutic management by analogy between this type of hydrocalyx and Fraley's syndrome.

Contrast-enhanced MR imaging of experimental acute tubular necrosis.

PURPOSE: To demonstrate the involvement of the various renal structures in acute tubular necrosis (ATN). MATERIAL AND METHODS: In 15 rats, using a T1-/T2-weighted sequence, either gadodiamide alone, or gadodiamide in combination with sprodiamide (a susceptibility agent) were used to enhance the various anatomical substrates of the kidney. The results were compared to those of pathological verification. RESULTS: Experimentally induced ATN of the rat kidney causes profound changes in the medulla, leaving the cortex largely intact. The difference between the normal cortex and the partially necrotic outer medulla, on the one hand, and the papillary region, was significantly enhanced with the combination, whereas a larger region composed of the inner and outer medulla was enhanced after the gadolinium chelate alone. CONCLUSION: The results varied considerably between the two procedures; the double contrast demonstrated a clear difference between the inner and outer medulla, and the gadolinium chelate alone demonstrated a clear difference between the medulla and the cortex. These results demonstrated a clear difference in the compartmentalization between the inner and outer medullary regions, providing complementary information about the pathological condition of the kidney.
