ABSTRACTPurpose:To evaluate the patient and stone related factors which may influence the final outcome of SWL in the management of ureteral stones.Materials and Methods:Between October 2011 and October 2013, a total of 204 adult patients undergoing SWL for single ureteral stone sizing 5 to 15 mm were included into the study program. The impact of both patient (age, sex, BMI,) and stone related factors (laterality, location, longest diameter and density as CT HU) along with BUN and lastly SSD (skin to stone distance) on fragmentation were analysed by univariate and multivariate analyses. Results: Stone free rates for proximal and distal ureteral stones were 68.8% and 72.7%, respectively with no statistically significant difference between two groups (p=0.7). According to univariate and multivariate analyses, while higher BMI (mean: 26.8 and 28.1, p=0.048) and stone density values (mean: 702 HU and 930 HU, p<0.0001) were detected as statistically significant independent predictors of treatment failure for proximal ureteral stones, the only statistically significant predicting parameter for the success rates of SWL in distal ureteral stones was the higher SSD value (median: 114 and 90, p=0.012).Conclusions:Our findings have clearly shown that while higher BMI and increased stone attenuation values detected by NCCT were significant factors influencing the final outcome of SWL treatment in proximal ureteral stones; opposite to the literature, high SSD was the only independent predictor of success for the SWL treatment of distal ureteral stones.

ABSTRACTObjective:We aimed to evaluate the possible effects of ureteroscopic procedures on the sexual function of both genders.Materials and Methods:A total of 102 sexually active cases (60 male, 42 female) undergoing ureteroscopic procedures were included in this study. Sexual function has been evaluated in detail by using International Index of Erectile Function (IIEF) in male and Female Sexual Function Index (FSFI) forms in female cases both before and 1-month after the procedures. Pre-and postoperative data were evaluated in a comparative manner.Results:The pre-and postoperative mean IIEF scores were 57.86±2.26 and 54.57±2.48 (p=0.19) in males and the mean FSFI scores were 13.58±1.46 and 14.46±1.52 (p=0.41), respectively in females. Evaluation of these values showed that regarding the effects of this procedure on male cases although the total scores for sexual function were not influenced it was observed a significant reduction in the intercourse satisfaction sub-domain (IIEF-IS) in males (p<0.05). In female cases however, unlike the male cases no statistically significant alterations with respect to these scores were noted (p=0.418).Conclusion:Ureteroscopic interventions could have some adverse effects on the sexual function particularly in male cases. However, it is clear that further prospective studies in both genders with large population of cases are certainly needed in order to outline this unresolved but important subject.

PURPOSE: A considerable percentage of patients with benign prostatic hyperplasia (BPH) also have additional cardiac pathologies, which often require anticoagulant therapy. The aim of this study was to evaluate the efficacy and safety of photoselective vaporization of the prostate (PVP) for BPH in cardiac patients receiving anticoagulant therapy. MATERIALS AND METHODS: A total of 67 patients suffering from BPH and high risk cardiac pathologies were operated on using laser prostatectomy. All patients had cardiac pathologies with bleeding disorders requiring anticoagulant use, and underwent standard urologic evaluation for BPH. Patients were treated with laser prostatectomy for relief of the obstruction using the KTP/532 laser energy at 80 W. RESULTS: The mean patient age was 71.4 years (range 55-80). Mean prostate volume on transrectal ultrasonography was 73.2 mL (range 44-120). Operation time ranged from 40 to 90 min, with an average value of 55 min. The average hospital stay was 48 hours (range 12-72) and the Foley catheters were removed within 48 hours, with a mean catheterization time of 34.2 ± 5.9 hours (0-48). No patient required an additional procedure due to severe bleeding necessitating intervention during the early postoperative phase. Mean International symptoms scoring system (IPSS) values and post voiding residual volume decreased and peak urinary flow rate increased (p < 0.001). Our results showed that the mean prostate volume had decreased by 53% at 6 months. CONCLUSIONS: High-power photo selective laser vaporization prostatectomy is a feasible, safe, and effective alternative for the minimal invasive management of BPH, particularly in cardiac patients receiving anticoagulant therapy.
