A number of factors that can impact the outcomes of percutaneous nephrolithotomy (PCNL) procedures have previously been investigated. Complex stones that extend to the anterior calyx could affect the success and complication rates of PCNL.We analyzed the effect of anterior calyx involvement on the outcomes of patients with complex stones treated with PCNL.A total of 132 consecutive patients who underwent PCNL due to complex stones (multiple, partial staghorn, or staghorn stones) between 2015 and 2017 were enrolled in this study. They were stratified into two groups based on whether the stone extended to the anterior calyx (group 1, n = 45) or not (group 2, n = 87). The stratification was achieved through contrast-enhanced computerized tomography (CT). Demographics, laboratory tests, and peri- and postoperative findings (operation and fluoroscopy duration, hospital stay, utilization of flexible instruments, access numbers, total blood count change, stone-free rate [SFR], and complications) were compared between the groups. The SFR was evaluated by plain kidney-ureter-bladder radiography or CT.The demographics, operation and fluoroscopy duration, access number, and hospital stay were similar between the groups (p0.05). A higher drop in the hemoglobin level in group 1 was identified (group 1 [2.14 ± 1.49 g/dL] vs. group 2 [1.43 ± 1.31 g/dL]) (p = 0.006). The SFR among the patients with extension to the anterior calyx was 60%, compared to 77% among the patients with no extension to the anterior calyx (p = 0.041). Flexible instruments were utilized in 60% of the patients of group 1, which was a higher rate than for group 2 (36%) (p = 0.007). Complication rates were similar in the two groups according to the Clavien-Dindo classification (p0.05).Our study demonstrated that complicated stones with extension to the anterior calyx are more challenging than cases without extension to the anterior calyx. This was noted by a lower SFR, a more prominent drop in total blood count, and more frequent utilization of flexible scopes.

Objective: The aim of this study was to evaluate the safety and efficacy of retropubic (RP) or transobturator (TO) midurethral slings (MUS) in a prospective randomized cohort of Turkish women. Patients and Methods: A total of 54 women with urodynamic stress urinary incontinence (SUI) were randomized to undergo either RP or TO MUS between August 2006 and February 2013 in a tertiary referral center by a single surgeon. All patients had history, physical examination, urodynamic evaluation and quality of life assessments. The validated Turkish versions of the SEAPI, ICIQ-SF and OAB-V8 questionnaires were used. The Advantage® RP and the Obtryx® TO MUS Systems were used for all RP and TO procedures. Results: Twenty-seven patients were randomized to each group. The median follow-up was 48.5 ± 21.8 months. The median hospital stay was 24.0 ± 4.8 h and median operative time was 35.0 ± 19.9 min. The overall objective and subjective cure rates were 92.6 and 79.6%, respectively. The quality of life of all patients significantly increased after the operation compared to their preoperative status. Patients with a poorer subjective cure rate were those with mixed urinary incontinence, whose preoperative SEAPI and OAB-V8 scores were significantly higher. Conclusion: MUS surgery is highly effective and could safely be performed in a cohort of Turkish women with SUI in subspecialty centers by experienced surgeons. There is no significant difference between RP or TO applications in terms of safety and efficacy. Further studies with long-term follow-up data are required.
