1.  Outcome of urethral strictures treated by endoscopic urethrotomy and urethroplasty 
We analyze the outcomes of patients with urethral stricture who underwent surgical treatment within the past 5 years.
This is a retrospective study of male patients who underwent surgery for urethral stricture at our service from January 2008 to June 2012. We analyzed the comorbidities, type, length and location of the stricture and the surgical treatment outcome after endoscopic urethrotomy, urethroplasty or both.
In total, 45 patients with a mean age of 53.7 ± 16.7 years underwent surgical treatment for urethral stricture. Six months after surgery, 46.7% of the patients had a maximum urinary flow greater than 15 mL/s, whereas 87.3% of the patients exhibited no stricture by urethrography after the treatment. The success rate in the patients undergoing urethrotomy was 47.8% versus 86.4% in those undergoing urethroplasty (p = 0.01). Twenty percent of the patients in whom the initial urethrotomy had failed subsequently underwent urethroplasty, thereby increasing the treatment success.
In most cases, the treatment of choice for urethral stricture should be urethroplasty. Previous treatment with urethrotomy does not appear to produce adverse effects that affect the outcome of a urethroplasty if urethrotomy failed, so urethrotomy may be indicated in patients with short strictures or in patients at high surgical risk.

2.  Clinical Efficacy in the Treatment of Overactive Bladder Refractory to Anticholinergics by Posterior Tibial Nerve Stimulation 
Korean Journal of Urology  2012;53(7):483-486.
Overactive bladder (OAB) is a clinical syndrome that is currently treated initially with anticholinergics, although some other therapeutic alternatives exist, such as neuromodulation, botulinum toxin, and posterior tibial nerve stimulation (PTNS). The purpose of this study was to assess the efficacy of PTNS in patients with OAB refractory to anticholinergics.
Materials and Methods
We present a cohort study of 14 women with OAB to whom we applied PTNS. We assessed (before and after the treatment) the diurnal micturitional frequency, the nocturnal micturitional frequency, urgency episodes, and urge incontinence episodes. Results were analyzed by using the Wilcoxon test for nonparametric samples.
We observed statistically significant improvement in the diurnal micturitional frequency (p=0.05), in episodes of micturitional urgency (p=0.03), and in episodes of urge incontinence (p=0.004). A total of 50% of the patients felt subjective improvement from their pathology.
PTNS is a valid, minimally invasive treatment option with minimum morbidity for patients with OAB refractory to treatment with anticholinergics.
