Fascial slings and bladder neck tapering in the treatment of male neurogenic incontinence.
Intractable incontinence in selected male patients with a neurogenic bladder has been treated by increasing bladder compliance with augmentation cystoplasty and increasing urethral resistance with the artificial urinary sphincter. However, there are a number of complications associated with the use of an artificial urinary sphincter. As an alternative, we performed bladder neck tapering and bladder neck slings in 13 men with a neurogenic bladder and an incompetent urethra (10 with spina bifida and 3 with spinal cord injury) undergoing bladder augmentation. Mean patient age was 27 years (range 17 to 40 years) and mean followup was 34.3 months (range 5.5 to 49 months). Postoperatively, there was a 113% increase in mean bladder capacity (from 260 to 550 cc) and a 62% decrease in mean bladder pressure at capacity (from 53 to 20 cm. water). The earliest 2 patients with a Marlex sling suffered erosions that were treated with transurethral excision. As a result, the 11 subsequent patients had a rectus fascial sling. Nine patients (69.2%) are completely dry on self-catheterization, 2 (15.4%) required collagen injections for improved continence and 2 failures (15.4%) required additional procedures. The complications in these patients are comparable to, if not better than, the use of an artificial urinary sphincter. We conclude that a fascial sling with bladder neck tapering is an excellent alternative to the artificial urinary sphincter in the treatment of male neurogenic bladder with an incompetent urethra.

Evaluation and treatment of blunt renal trauma.
We examined retrospectively the records of 126 patients with blunt renal trauma to determine the criteria for radiological investigations and the imaging study of choice. Of the 3,993 patients admitted to our regional trauma unit during the last 13 years 126 (3.1%) had blunt renal trauma. Mean patient age was 32 years (range 13 to 87 years) and the male-to-female ratio was 3:1. Mean followup was 7 months (median 4 months). Of the patients 72% had a minor renal injury, 17% had a moderate injury and 11% had a major renal injury. Treatment was conservative in 114 patients, while 9 underwent a genitourinary operation. Results were excellent in 87% of the patients and good in 8%, while 5% failed treatment. All patients who had microscopic hematuria without shock had minor injuries. Excretory urograms (IVPs) were normal in 74% and 39% of the patients when performed for minor and moderate renal injuries, respectively. Computerized tomography (CT) was abnormal in all cases when performed, and was more sensitive and specific than an IVP. Therefore, the majority of patients with blunt renal trauma can be treated conservatively with an excellent result. Furthermore, radiological investigations are not needed in those with microscopic hematuria and no shock. When radiological investigations are indicated a CT scan is the imaging study of choice.

Inflammatory abdominal aortic aneurysms and ureteric obstruction.
Inflammatory abdominal aortic aneurysms are rare, but when they occur the ureters may be involved in the perianeurysmal fibrosis. Treatment of this ureteric involvement is controversial. The authors present one such case, review the literature and describe what they believe is the appropriate method of diagnosis and treatment. This includes the use of computed tomography, retrograde pyelography, ureteral stenting, repair of the aneurysm and ureterolysis.
