Review Case Reports
Leech therapy in penile replantation: a case of recurrent penile self-amputation.
Penile amputation is a rare urologic trauma for which immediate surgical replantation is indicated. Microsurgical techniques can reduce skin and graft loss complications; nonetheless, such complications are still highly prevalent. We report a case of self-inflicted penile amputation and describe a nonmicrosurgical technique for replantation. ⋯ The edema quickly resolved, but overlying skin loss occurred, which required superficial debridement. At follow-up the patient had glans re-epithelialization with normal voiding, sensation, and erections. To our knowledge, this is the first reported case of nonmicrosurgical penile replantation with leech therapy.

Randomized Controlled Trial Clinical Trial
No reason for immediate repeat sextant biopsy after negative initial sextant biopsy in men with PSA level of 4.0 ng/mL or greater (ERSPC, Rotterdam).
In the early detection of prostate cancer (CaP) uncertainty exists concerning the most appropriate biopsy procedure. Within the European Randomized Study of Screening for Prostate Cancer (ERSPC) lateralized sextant biopsies are used. False-negative results of sextant biopsies have led to the extensive use of procedures using 12 or more biopsy cores. The ERSPC offers the opportunity to study the yield of repeat biopsies after 4 years in men who had negative sextant biopsies and a prostate-specific antigen (PSA) level of 4.0 mg/mL or more at the first screening round. ⋯ Although the results of this study may have been biased by the low rate of availability/eligibility of participants for rescreening (after 4 years), the proportion of cancers detected after a previous lateral sextant biopsy indicated by a PSA value of 4.0 mg/mL or more (PPV 8.3%) fell far short of the overall PPV at rescreening (PPV 20%). The features of most cancers that were possibly missed during the first round allowed a potentially curative approach. The ERSPC study group found no reason to change the ERSPC protocol.

To determine whether delayed excision and primary anastomosis is appropriate after failed previous therapeutic attempts for post-traumatic membranous urethral strictures. Delayed excision and primary anastomosis is widely accepted as the first-line treatment of post-traumatic membranous urethral strictures. ⋯ Even in patients with failed previous surgical attempts, excision and primary anastomosis is feasible and provides good surgical results in post-traumatic posterior urethral strictures. The complications were mild and easily treated.

To evaluate the volume-outcome relationship in patients undergoing nephrectomy for neoplastic disease by examining the impact of the number of cases performed on in-hospital mortality and length of stay. Surgical volume is associated with postoperative mortality for many complex procedures; however, this relationship has not been characterized for patients undergoing nephrectomy for neoplastic disease. ⋯ A greater surgical volume, age younger than 65 years, elective conditions, and less comorbidity are associated with a significantly decreased risk of in-hospital mortality after nephrectomy. These findings provide compelling evidence that hospital volume and patient characteristics have important effects on surgical outcome specific to renal neoplasms.

Comparative Study
Safety and efficacy of percutaneous nephrolithotomy in patients with neurogenic bladder dysfunction.
To review our experience performing percutaneous nephrolithotomy (PNL) on patients with neurogenic bladder dysfunction with special attention paid to the risks of surgical complications and stone recurrence. Patients with neurogenic bladder dysfunction with or without urinary diversion are at increased risk of urolithiasis, surgical complications, and recurrent stone disease. ⋯ PNL in patients with neurogenic voiding dysfunction is safe and effective, with outcomes comparable to that of patients without such lesions. The complication rate is small but statistically significant. It is important to obtain adequate urine cultures, because renal pelvis and bladder culture data may differ and affect the outcome. Risk factors for recurrent stone disease include a high spinal cord lesion, indwelling urinary catheter, and ureterosigmoidostomy.
