Retroperitoneoscopic bilateral nephrectomy and extraperitoneal ureterocystoplasty in a child on peritoneal dialysis.

Botulinum Toxin A Injection in the Bladder Neck: A Promising Treatment for Urinary Retention.

Secondary to failure of optimal medical therapy and the high morbidity that accompanies surgical techniques in high risk patients, the use of de novo treatments including botulinum toxin A is emerging in the treatment of benign prostatic hyperplasia (BPH).
