SUMMARYUdenafil is a potent phosphodiesterase type-5 inhibitor (PDE5) previously shown in studies conducted in populations of EasternAsian ethnicity, to significantly improve sexual function, in addition to a favourable safety profile. The purpose of this study was to evaluate the efficacy and safety of udenafil for the treatment of erectile dysfunction (ED), for the first time in a non-Eastern-Asian population. In this multicentre, randomized, double-blind, parallel, placebo-controlled study conducted in five centres in Turkey, 118 eligible subjects were randomized to receive udenafil 100 mg taken as on-demand or matching placebo for an 8-week treatment period. The primary efficacy variable was the change from baseline of the International Index of Erectile Function QuestionnaireErectile Function Domain (IIEF-EFD) score, secondary efficacy variables were changes from baseline in IIEF Questionnaire Domains' 2-5 scores (Intercourse Satisfaction, Orgasmic Function, Sexual Desire, Overall Sexual Satisfaction) and IIEF Questionnaire Grand Total score, changes from baseline in penetration success rates (SEP2) and intercourse completion rates (SEP3) and evaluation of responses to the global assessment question (GAQ). Patients treated with udenafil demonstrated significantly higher increase in the IIEF-EFD scores compared with placebo-treated subjects [4.0 (95% CI: 1.3-6.6; p = 0.003)]. Similarly, greater improvements were observed in the scores for SEP2 [0.65 (95% CI: 0.02-1.3, p = 0.043)], SEP3 [0.9 (95% CI: 0.3-1.5, p = 0.003)] and two other IIEF Questionnaire Domains (Domain 4: Sexual Desire, Domain 5: Overall Sexual Satisfaction). The proportion of positive responses to the GAQ was greater in the udenafil compared to the placebo group (72.2% vs. 49.1%, p = 0.014). The most frequent treatment-emergent adverse events were headache, flushing and rhinorrhea, all of mild or moderate severity. This is the first study to demonstrate in a non-Eastern-Asian population that udenafil 100 mg taken as on-demand can effectively improve erectile function and is well tolerated.
Objective: Bladder wall thickness (BWTh) measurements and Nerve Growth Factor (NGF) /creatinine (Cr) values, as noninvasive tools, were found to predict daytime voiding problems in children with overactive bladder (OAB). The goal of this research was to examine if bladder wall thickness together with urine NGF/Cr could be a clinical utility in treatment outcome of OAB in children. Patients and Methods: A total of 60 children with OAB, (Group 1; n=40) and healthy normal controls (Group 2; n=20), aged 6-14 years old were involved in this prospective study. Children were evaluated with detailed history and physical examination, including neurologic examination, and were asked to complete a self-reported questionnaire and a 3-day bladder diary with the aid of their parents. Urofl owmetry was performed in all cases. Urinary nerve growth factor levels were measured by the ELISA and BWTh was measured trans-abdominally by one uro-radiologist specialized in pediatric ultrasonography. Urinary NGF levels were normalized by urinary creatinine levels and compared among all subgroups. Children with OAB received urotherapy as fi rst line treatment at least for three months. 18 children refractory to urotherapy received anticholinergic therapy defi ned as group 3. Results: The median age of the study group was 10 (range 6 to 16). After urotherapy, 22 children had similar BWTh and NGF/Cr values compared to controls. (2.75 ± 1.15; 2.40 ± 1.00 mm; p=0.86 and 1.02 ± 0.10; 0.78 ± 0.15; p=0.12, respectively). After anticholinergic treatment, BWTh levels (2.25 ± 0.90; 2.40 ± 1.00 mm; p=0.94) and NGF/Cr values (0.95 ± 0.10; 0.78 ± 0.15; p=0.42, respectively) had no signifi cantly difference compared to controls (Group 2). In receiver operating characteristic analysis, bladder wall thickness was found to have sensitivity of 85% and specifi city of 84.2% (3,20 AUC ,913; 95 %) and NGF/Cr had sensitivity of 90% and specifi city of 92.1% (1,595; AUC ,947; 95 %) in predicting treatment outcome in children with OAB. Conclusions: Bladder wall thickness measurements and NGF/Cr values, as noninvasive tools, could guide outcomes in the treatment of children with overactive bladder.
Objective: In this study we aimed to compare photoselective vaporization (PVP) with the GreenLight 120-W Laser and monopolar transurethral resection as surgical treatments of prostates less than 80 cc in men with obstructive benign prostatic hyperplasia. Methods: From February 2009 to March 2012 we allocated 101 patients with a prostate glands of less than 80 cc; patients were randomly assigned for surgical treatment with monopolar transurethral resection of the prostate (TURP) (n = 62) or PVP (n = 39). Serum prostate specific antigen (PSA), International Prostate Symptom Score (IPSS), Sexual Health Inventory for Men (SHIM), maximum flow rate (Q max ) postmicturition residual (PMR), transrectal ultrasound volumes (TRUS), postvoid urine residual (PVR), complications, re-operations and hospitalization time were collected. The patients were seen in the follow up at 6, 12 and 24 months. Results: Median age was 69 (56-87) years old in the TURP group and 67 (51-87) years old in the PVP group. Mean preoperative prostate volume was 55 cc (40-72) and 60 cc (41-75) cc in the TURP group versus the PVP group. There was no statistically difference in subjectively (IPSS, SHIM) and objectively (Q max -PMR) parameters and postoperatively complication rates between the two groups (p > 0.05). A significant difference was observed in the PVP group with a 2 (1-4) days hospital stay compared with 5 (3-9) days for the TURP group (p < 0.001). Conclusion: Prostate PVP and TURP are effective surgical treatments for benign prostatic hyperplasia. Postoperative functional improvements were durable and equivalent in the two groups. The two techniques have a similar complication rate.
ÖZIt has been 15 years since the Food And Drug Administration approved the Da Vinci® robotic surgery system. Robotic applications are being used extensively in urology, particularly in radical prostatectomy. Like all hightech products, this system also has a high cost and a steep learning curve, therefore, preventing it from becoming widespread. There are various studies on the effect of open surgery or laparoscopy experience on the learning curve of robotic surgery. Analyzing these interactions well will provide valuable information on making the training period of robotic system more efficient.
