Treatment of renal stones with flexible ureteroscopy in preschool age children

WOS: 000336383500008PubMed ID: 24374900The aim of the study is to evaluate the efficacy and safety of retrograde intrarenal surgery (RIRS) to treat renal stones in preschool age ( 4 mm, a second-stage RIRS was performed. The pre-operative, operative and post-operative data of the patients were retrospectively analyzed. A total of 65 patients with a mean age of 4.31 +/- A 1.99 years (6 months-7 years) were included in the present study. The mean stone size was 14.66 +/- A 6.12 mm (7-30 mm). The mean operative time was 46.47 +/- A 18.27 min. In 5 (7.69 %) patients, the initial procedure failed to reach the renal collecting system and ended with the insertion of a pigtail stent. The stone-free rates were 83.07 and 92.3 % after the first and second procedures, respectively. Complications were observed in 18 (27.7 %) patients and classified according to the Clavien system. Post-operative hematuria (Clavien I) occurred in 6 (9.2 %) patients, post-operative urinary tract infection with fever (Clavien II) was observed in 10 (15.4 %) patients, and ureteral wall injury (Clavien III) was noted in 2 (3 %) patients. RIRS is an effective and safe procedure that can be used to manage renal stones in preschool age children

The Effect of Obturator Nerve Blockade on Oncological Outcomes of Patients with Lateral Wall Localized Non-Muscle Invasive Bladder Cancer

Objective:To investigate the effect of obturator nerve blockade on oncological outcomes of patients with a diagnosis of lateral wall localized non-muscle invasive bladder cancer.Materials and Methods:One hundred six patients diagnosed with lateral wall localized non-invasive bladder cancer were evaluated between January 2015 and March 2020 in this retrospective, cross-sectional observational study. The patients were divided into two groups: patients receiving only spinal anesthesia and those receiving spinal anesthesia combined with ultrasound-guided obturator nerve blockade. Oncological outcomes of the groups were compared statistically.Results:We observed recurrent tumors in 25 patients (45.5%) in Group 1 and 11 patients (21.6%) in Group 2. Additionally, we observed tumor progression in eight patients (14.5%) in Group 1 and two patients (3.9%) in Group 2. We observed statistical significance in differences between groups regarding tumor size, recurrence rate, adequate muscle tissue sampling, ability for complete resection, and persistent obturator reflex. The efficacy rate of obturator blockade was 92.1% in Group 2. One-year recurrence-free survival (RFS) was 98.0% and 5-year RFS was 23.5% for Group 1, while for Group 2, they were 97.4% and 57.2%, respectively.Conclusion:The obturator reflex is a common and challenging reflex that may cause major complications and result in unintended consequences, such as incomplete resection or tumor recurrence with transurethral resection of bladder tumors. In this study, we demonstrated that combining spinal anesthesia with obturator nerve blockade for lateral wall localized non-muscle invasive bladder cancer may prevent tumor recurrence and reduce peroperative complications
