Spinal dysraphism at MR urography: initial experience.

PURPOSE: To prospectively evaluate the role of magnetic resonance (MR) urography in the radiologic assessment of patients with spinal dysraphism. MATERIALS AND METHODS: Fourteen patients with spinal dysraphism were referred for MR urography with half-Fourier rapid acquisition with relaxation enhancement (RARE) (repetition time msec/echo time msec = 11.9/95) and RARE (2,800/1,100) sequences on a 1.5-T MR machine. Six patients did not tolerate MR urography owing to claustrophobia (n = 4) or flexion deformities (n = 2), giving a final success rate of 57% (eight patients). Two patients had a single kidney (one after nephrectomy, one with a crossed-fused ectopic kidney). Images were jointly assessed by two radiologists and compared with excretory urographic studies. The signal intensity ratio and contrast-to-noise ratio were also calculated. RESULTS: Visualization of the kidneys, pelvicaliceal system, and ureters was better with half-Fourier RARE than with RARE imaging, whereas visualization of the bladder was comparable with both sequences. The mean signal intensity ratios for half-Fourier RARE and RARE sequences, respectively, were 16.2 +/- 3.65 and 19.2 +/- 3.65 (P =. 58, factorial analysis of variance model), whereas the mean contrast-to-noise ratios were 55.4 +/- 5.16 and 47.8 +/- 5.16 (P =. 34). Cortical scarring was depicted more clearly at MR urography than at excretory urography, whereas a renal calculus seen at excretory urography was not detected at MR urography. CONCLUSION: MR urography was feasible in 57% of patients with spinal dysraphism and is a safe, accurate method of evaluating the upper urinary tract.

Prognostic factors in squamous cell carcinoma of the penis and implications for management.

OBJECTIVE: To determine the clinical and pathological features, methods and outcome of management in squamous cell carcinoma of the penis (SCCP). PATIENTS AND METHODS: A retrospective study was carried out of 42 patients (mean age 63 years, range 28-86) with a histological diagnosis of SCCP. The disease stage, grade, treatment of primary tumour, lymph node disease and survival were recorded; the mean follow-up was 4 years (range 1.5-25). RESULTS: The disease stage was T1 in 24 patients (57%), T2 in 14 (33%), T3 in three (7%) and T4 in one (2%); the tumour grade was well differentiated in 20 (47%), moderately differentiated in 14 (33%) and poorly differentiated in three (7%). Eight patients had histologically confirmed inguinal node disease at presentation, six of whom underwent lymph node dissection, while two underwent radiotherapy. Five patients developed inguinal node disease during follow-up (mean 10 months, range 4-21). Three of these patients were irradiated and two underwent lymph node dissection. Six patients (14%) had local recurrence, five of whom were managed surgically. One patient developed a local recurrence 11 years after initial surgery. Seven patients died from their disease (17%); four died within 2 years, being patients with high-stage and/or high-grade disease. CONCLUSIONS: Modern management should include a standard staging classification and treatment protocols to maximize survival.

Urological complications of pancreatic transplantation.

PURPOSE: Pancreas transplantation is increasingly being used in the treatment of type I insulin-dependent diabetes mellitus. Because bladder drainage of the exocrine pancreatic secretion is the procedure of choice, urological complications are frequent. As the number of these procedures increases the urologist will have an extended role in the management of the postoperative complications, the majority of which are urological. MATERIALS AND METHODS: The literature from 1985 on the complications related to pancreas transplants was reviewed. RESULTS: Approximately 50 to 60% of bladder drained pancreas transplant recipients will have a urological complication postoperatively. CONCLUSIONS: The increasing application of bladder drained pancreas transplantation in the treatment of type I insulin-dependent diabetes mellitus necessitates that the clinical urologist is familiar with the management of complications related to this procedure.

Fournier's gangrene of scrotum in a patient with AIDS.

Fournier's gangrene of the scrotum, a form of necrotising fasciitis, is a rare but potentially fatal disorder. Predisposing conditions include chronic alcoholism and diabetes mellitus, possibly as a result of impaired immunity. Fournier's syndrome, occurring in a patient with AIDS, is described.
