A treatment strategy to help select patients who may not need secondary intervention to remove symptomatic ureteral stones after previous stenting

This study aimed at evaluating whether removal of the ureteral stent the day before scheduled secondary intervention facilitates spontaneous ureteral stone passage and thus can spare the pre-stented patient this surgery.MethodsRetrospective analysis of a single-centre consecutive series of 216 patients after previous stenting due to a symptomatic ureteral stone from 01/2013 to 01/2018. Indwelling stents were removed under local anaesthesia. Patients were told to filter their urine overnight. Multivariate analysis was performed to assess predictive factors for spontaneous stone passage.Results34% (74/216) of patients had spontaneous stone passage while the stent was indwelling. Of the remaining 142 patients, 41% (58/142) had spontaneous stone passage within 24  h after stent removal. Only 84/216 (39%) patients needed secondary intervention. Multivariate logistic regression analysis of all 216 patients showed a significant association between spontaneous stone passage and smaller stone size (p

In this report, we presented the analgesic efficacy of QLB in 15 patients, which included nine renal and six ureter stones for ESWL. The mean of the VAS scores ranged from 0.20±0.41 to 2.73±1.22, and mean fentanyl consumption was 15.00±15.08 mcg during the procedure. No opioid-related side effects were observed in any of the patients. Full fragmentation was obtained in nine of the 15 patients, and partial fragmentation was obtained in five patients.

Introduction: Patients with motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), have higher sensitivity to nondepolarizing neuromuscular blocking agents (NMBAs) and are at higher risk for a residual block. For this reason, the use of NMBAs such as rocuronium has been limited owing to the delayed reversal of muscle relaxation. It was recently reported that rapid and effective reversal of muscle relaxation occurs when sugammadex, a muscle relaxant reversal drug, is administered to patients in ALS with rocuronium-induced muscle relaxation. However, in this paper, we report the incomplete recovery and recurar...

We present a case of ureteral catheter placement wherein the patient required readmission for renal failure with intervention under local anesthesia. This case highlights the importance of patient selection for catheter placement and clinical follow-up, as well as the need for prospective studies to determine the risk-benefit ratio of preoperative catheters.

ABSTRACT Purpose We aimed to compare the outcomes of supine and prone miniaturized percutaneous nephrolithotomy (m-PNL) in the treatment of lower pole, middle pole and renal pelvic stones. Materials and Methods 54 patients who performed supine m-PNL between January 2017 and March 2018 and 498 patients who performed prone m-PNL between April 2015 and January 2018 were included in the study. Of the 498 patients, 108 matching 1: 2 in terms of age, gender, body mass index, American Association of Anesthesiology score, stone size, stone localization and hydronephrosis according to the supine m-PNL group were selected as prone m...

Since this minimally-invasive technique has been introduced in patients with aberrant lower-pole vessels, multiple publications have reported successful short, intermediate and long-term outcomes.

Indwelling ureteral stents are commonly placed in urologic surgeries where optimal urinary drainage is necessary. In the pediatric population, removing a stent without retrieval string (SWOS) requires a secondary operation and additional anesthetic exposure. While these burdens can be mitigated through the placement of stents with retrieval strings (SWS), fears of complications may prevent widespread adoption of this practice by pediatric urologists.
