Randomized Controlled Trial Comparative Study
Doxazosin versus tizanidine for treatment of dysfunctional voiding in children: a prospective randomized open-labeled trial.
To examine the efficacy and tolerability of tizanidine for the treatment of dysfunctional voiding in children compared with those of doxazosin. ⋯ Tizanidine could be a safe and effective treatment of children with dysfunctional voiding due to pelvic floor/skeletal sphincter dysfunction. More placebo-controlled trails with larger sample sizes are needed.

To compare the outcomes of patients treated in the perioperative setting with methotrexate, vinblastine, adriamycin, and cisplatin (MVAC) versus gemcitabine and cisplatin (GC). Systemic cisplatin-based chemotherapy regimens are the mainstay of treatment for patients with advanced bladder cancer. GC has often been used interchangeably with MVAC in neoadjuvant or adjuvant settings for patients with locally advanced (cT2N0M0-cT4N2M0) bladder cancer without adequate evidence. ⋯ Despite the lack of data on the relative efficacy of GC versus MVAC in the neoadjuvant and adjuvant settings, these regimens have been used interchangeably. The present investigation did not find the choice of cisplatin-based regimen to be an independent predictor of survival. A trend was seen toward improved survival and a greater complete response rate in the MVAC group.

A middle-age man presented with acute urinary retention and a history of passage of urine and stones through a fistula at the root of the penis of 7 years' duration. Computed tomography of the soft tissue penis revealed multiple calculi in the urethra. ⋯ Intraoperatively, dense stricture of the distal penile urethra was found, with complete obliteration in places. A urethral stricture, if not promptly managed, can lead to devastating complications necessitating complex surgical management.

To evaluate the effects of warm ischemia time (WIT) and quantity and quality of kidney preserved on renal functional recovery after partial nephrectomy (PN). The effect of WIT relative to these other parameters has recently been challenged. ⋯ Our results have validated that the quality and quantity of kidney are the most important determinants of renal function after PN. In addition, we have also demonstrated that the WIT remains an important modifiable feature associated with short- and long-term renal function. The precision of surgery, maximizing the amount of preserved, vascularized parenchyma, should be a focus of study for optimizing the PN procedure.
