ABSTRACT
OBJECTIVES: The purpose of this study was to develop a fast, comfortable, and safe method of ureteral stent removal in women. METHODS: From February 2014 to July 2015, a retrospective multicenter controlled study including 82 female outpatients was conducted. The control group was composed of 46 patients who underwent stent removal using a 22F cystoscope. The experimental group was composed of 36 patients who underwent stent removal under ultrasound guidance with a 15F spiral-ending device. Exclusion criteria were pelvic organ prolapse quantification stage II or higher and complicated stents (with migration or encrustation). RESULTS: All studied patients had successful ureteral stent removal. No complications were seen in both groups. Differences between mean visual analog pain scale scores and stent removal durations were statistically significant in favor of the experimental group (P = .0077 and .0075, respectively). CONCLUSIONS: The proposed method for ureteral stent removal in women under ultrasound guidance was shown to be faster and to have lower visual analog pain scale scores, in comparison with removal by a cystoscope, which makes it an attractive option for outpatient urologic praxis in uncomplicated cases, and because it is free of the risk of ionizing radiation and more comfortable, it can be used in pregnant patients.

PURPOSE: To investigate the usefulness of Plasticine biomodeling in surgical percutaneous management of complex renal stone. PATIENTS AND METHODS: A total of 32 patients with complex renal stones (complete staghorn stones or partial staghorn stone with multiple caliceal stones) were included in this study from 2012 to 2013. Computed tomography (CT) urography with three-dimensional (3D) reconstructions was used as standard preoperative imaging in all patients. Preoperatively, Plasticine replication of the pelvicaliceal system was performed by the operating surgeon, based on the gathered 3D reconstructions. Then the model was taken to the operating room and used as a reference model in a sterile polyethylene bag during the operation. RESULTS: Percutaneous renal access was achieved successfully in all cases. Twenty-nine (91%) patients were treated in the prone position and only 3 (9%) in supine position. There were 18 (56%) patients who had a single tract, 9 (28%) patients had two tracts, 3 (9%) patients had three tracts, and one (3%) patient needed four tracts. The mean operative time was 92 (±26) minutes. Second-look percutaneous nephrolithotomy (PCNL) was needed in 9 of 32 (28%) patients. All second-look sessions were performed in 2 to 3 days and/or on a normalized temperature. Six of 11 (54.5%) patients with complete staghorn stones needed a second-look PCNL session. Complete stone clearance was confirmed by low-dose CT, performed at 24 hours after surgery, in 89.4% of the patients treated by a single PCNL session and 82% in those who needed second-look sessions. The overall stone-free rate (SFR) in the study after second looks was 87.3%. CONCLUSIONS: The proposed Plasticine 3D model seems to provide better preoperative renal collecting system appreciation and to serve as a reference tool during the operation, which in turn might increase SFRs and lower the complications rate after PCNL.

We report a rare case of vesico-acetabular fistula due to an improperly treated pelvic fracture with urinary stone formation in the joint cavity. This complication was related to an unrecognized mechanism of bladder wall entrapment in the acetabular floor defect during weight bearing. This situation led to several mistreatment decisions in our case and should be always considered by urologists dealing with patients after major pelvic trauma. In this case report, we analyze the publications related to this problem, discuss the main mechanisms of bladder wall damage after acetabular fracture, and propose tips for diagnosis and treatment.
