Adjustable slings versus other surgical methods in female stress urinary incontinence: a systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: The objective of this study was to evaluate the efficacy and safety of different adjustable slings compared to other surgical methods for the treatment of stress urinary incontinence (SUI) among women. METHODS: The inclusion criteria were as follows: randomized controlled trials (RCTs) and non-RCTs assessing adult women with SUI. The exclusion criteria were as follows: other types of urinary incontinence, studies that combined conservative interventions and pharmacological treatment, pregnant and lactating patients. Databases were searched up to November 2022 to identify articles evaluating the effectiveness and safety of different adjustable slings compared to other surgical methods for the treatment of SUI among women. The systematic review was conducted in accordance with the PRISMA 2020 checklist and registered in PROSPERO. Risk-of-bias assessment tools recommended by the Cochrane Society were used to evaluate the risk of bias in the included studies. RESULTS: Eighteen clinical trials were included in this systematic review, and 11 studies were included in the meta-analysis. Fourteen studies were RCTs, and four were retrospective studies. Only RCTs were included in the meta-analyses. There was no statistically significant difference in the objective cure rate, subjective cure rate, or long-term postoperative complication rate between Ajust single-incision mini-slings (SIMS) and standard mid-urethral slings (SMUS) or MiniArc SIMS. However, the operation time in the adjustable SIMS group was significantly shorter (RR = -4.20, 95% CI: [-7.51, -0.89], p = 0.01). CONCLUSIONS: This systematic review and meta-analysis revealed that adjustable SIMS is equally effective when compared with SMUS for the treatment of SUI among women. Moreover, the operation time for the adjustable SIMS was shorter. However, additional well-designed studies with standard outcome measures and complete follow-up periods will help to increase confidence in the choice of different options for treating SUI among women.

Modified shockwave propulsion lithotripsy improves the lower pole renal stone clearance.

The shockwave lithotripsy is an established modality for the treatment of urinary stone disease. The aim of the study was to present our modified shockwave lithotripsy (SWL) technique, a shockwave propulsion lithotripsy (SWPL) technique, for the treatment of lower pole renal stones and compare its clinical outcomes with the standard SWL technique. An evaluation of a prospectively collected database including 168 patients divided into two groups and treated with ultrasound-guided SWL (n = 80) and SWPL (n = 88) were included in our study. The data were collected between January 2016 and December 2021. Patients older than 18 years old with single lower pole stones sized up to 2 cm were included in the study. SWPL was associated with significant higher SFR compared to standard SWL (85.2 vs. 62.5%, p = 0.001) and required less applied shockwaves (2151 vs. 2502, p = 0.001). Most of the patients in both groups underwent only one SWL session. Overall, a 7.1% complication rate (12 out of 168 patients) was reported, with no difference between groups. In conclusion, our proposed SWPL technique was aimed to overcome difficulties associated with the gravity and anatomic specificities of the lower pole, increased SFR and decreased the need for additional treatment.

Effectiveness of ultrasound-guided shockwave lithotripsy and predictors of its success rate in pediatric population: A report from a national reference center.

OBJECTIVE: Shockwave lithotripsy (SWL) remains a well-established treatment modality for many of the pediatric renal and ureteral stones. Repeated SWL sessions carry limitations due to the use of general anesthesia and X-ray radiation. The objective of our study was to evaluate stone-free rate (SFR) of 1-session of SWL for the management of pediatric renal and ureteral stones less than 2 cm performed exclusively under ultrasound guidance and identify factors influencing its success. METHODS: The study utilized a retrospective cohort design including 124 consecutive pediatric patients with 133 renal and ureteral stones less than 2 cm whom SWL was performed in the period of January 2008 to December 2019. SWL procedures were performed by one expert surgeon in a single, national reference center, exclusively under ultrasound guidance using Modulith® SLK lithotripter. Follow-up was performed in post-SWL 2nd, 4th, 12th weeks and 6 months. RESULTS: The mean age of the children was 10 years (SD = 6.0) and the mean stone size was 10.4 mm (SD = 3.6 mm). Sedation type of anesthesia was used in 80 patients (64.5%). No major complication was developed, and no ureteral stenting was required in any of the patient following SWL. The SFR following 1-session of SWL was 88.0% at 12-week. Younger age (P = 0.002), sedation type of anesthesia (P = 0.001) and presence of radiolucent stones (P = 0.033) significantly improved post-SWL early stone clearance on univariate analysis, the latter being the only significant factor according to final model (P = 0.031). CONCLUSIONS: Ultrasound-guided SWL represents a safe and effective method for the management of both renal and ureteral stones in children. The SFR following 1-session of SWL at 12-weeks was achieved in 88.0%, the overall success rate after all SWL sessions reaching 91.7%. A higher success rate was observed in children harboring radiolucent stones.
