Stone analysis is an important part in the evaluation of patients having stone disease. This could orientate physician toward particular etiologies.Chemical and physical methods are both used for analysis. Unfortunately, chemical often inadequate to analyze accurately urinary calculi fail detect some elements into stone. Physical methods, counterpart, becoming more high-volume laboratories. The present manuscript will provide a review on analytic all information that should be included...
Flexible ureterorenoscopy (F-URS) plays a major role in the management of kidney stones. Ureteral access sheaths (UAS) are important tools for F-URS. In this study, we aimed to evaluate difference intrarenal pressures between different flexible ureteroscopes while using same UAS and calculate irrigation flow variance.Eight were tested with five on an artificial model measure flow. Irrigation at 60 cmH2O pressure was performed; amount recorded states operator channel: Free, laser fiber (272...
We tested the effects of tumor size, distribution and grade on progression-free survival in patients with upper tract urothelial carcinoma treated flexible ureteroscopy Ho:YAG laser photoablation.Included analysis were data 92 consecutive photoablation from 2003 to 2015 at a single tertiary care referral center. Stringent followup was offered according EAU (European Association Urology) guidelines. Progression during defined by upgrading, distant metastases and/or relapsing that could not be...
We compared the hydrocoated silicone stent (Coloplast Imajin® hydro) to Percuflex™ Plus (Boston Scientific) in terms of patient comfort and quality life after flexible ureteroscopy for stone disease over a 5-week prospective followup.This is multicenter, single-blind, prospective, randomized trial 141 patients treated with renal stones. Primary outcome was Ureteral Stent Symptom Questionnaire (USSQ) Body Pain Index recorded before Double-J® removal at day (D) 20. Secondary endpoints were...
Abstract We aimed to assess the occlusive effectiveness of open-ended vasectomy with mucosal cautery and fascial interposition determine factors associated occlusion failure. studied all vasectomies performed between September 1, 2020, August 31, 2021, by four surgeons from Quebec City, Quebec, Canada. Sociodemographic clinical characteristics were extracted electronic medical records. Occlusive was assessed in men at least one postvasectomy semen analysis (PVSA). The criteria adapted those...
We compared the results of low transscrotal mid raphe orchiopexy, high scrotal incision (Bianchi) and conventional inguinal approach in patients with palpable undescended testes.Orchiopexies performed between January 2003 September 2009 a minimum 3-month followup were included. Low (group 1) 2) to traditional 2-incision technique 3). retrospectively reviewed operative time, success as defined by or lower position testis, complications at 12 weeks 1 year postoperatively.A total 286...
We sought to evaluate the effect of holmium:yttrium-aluminum-garnet (Ho:YAG) laser exposure on ex vivo pig eyes and test protective action different glasses in preventing eye lesions case accident.We pointed tip a Ho:YAG fiber from distances (0, 3, 5, 8, 10, 20 cm, respectively) toward center pupil eye. The was activated for 1 or 5 seconds at three settings (0.5 J-20 Hz, J-10 2 respectively). experiment repeated using safety eyeglasses. A total 78 were used. effects assessed by...
To describe our initial experience with confocal laser endomicroscopy (CLE) for the evaluation and treatment of patients upper urinary tract transitional cell carcinoma (UUT-TCC).Preliminary data were analyzed from 11 suspicion UUT-TCC scheduled flexible ureteroscopy (f-URS) consensual holmium-YAG tumor ablation. CLE was performed before endoscopic biopsy photoablation suspected lesion using a 3F-diameter probe UroFlex™ B (Cellvizio® system; Mauna Kea Technologies, Paris, France), which...
We sought to test the content validity of a new training model for flexible ureteroscopy: Key-Box.Sixteen medical students were randomized undergo 10-day consisting performing 10 different exercises aimed at learning specific movements with ureteroscope, and how catch release stones nitinol basket using Key-Box (n = 8 in group, n nontraining control group). Subsequently, an expert endourologist (O.T.) blindly assessed skills acquired by whole cohort through two on ureteroscope manipulation...
Over the last two decades there has been an increase in incidence of kidney stone disease with a simultaneous rise use ureteroscopy for its management [1]. Flexible training is variable and still largely dependent on high fidelity models virtual reality (VR) simulation, both which are expensive not readily available many parts world. There also lack good quality bench trainers. In recent survey endourologists worldwide, flexible was considered as first line treatment stones <2 cm [2]. With...
Purpose: To propose and evaluate a new endoscopic technique using only retrograde ureteroscopic approach for the removal of heavily encrusted ureteral stents. Methods: Data from 51 consecutive patients with retained stents were prospectively collected. Description successive steps surgery is detailed. The holmium yttrium aluminum garnet (Ho:YAG) laser properties offer opportunity fragmentation stent-attached encrustation ability to cut stent itself. Reducing length critical creating space in...
Objective: To study urinary stone composition patterns in different populations around the world. Materials and methods: Data were collected by reviewing charts of 1204 adult patients 10 countries with renal or ureteral stones (> 18 years) whom a analysis was done available. Any method accepted, but methodology had to be registered. Results: In total, we observed 710 (59%) calcium oxalate, 31 (1%) phosphate, 161 (13%) mixed oxalate/calcium 15 carbapatite, 110 (9%) uric acid, 7 (< 1%)...
Vesicoureteral reflux is frequently diagnosed in the pediatric population. Endoscopic treatment has become a popular form of first-line therapy. Available products offer good short-term success rates. However, cost these injected implants an issue. We evaluated endoscopic for vesicoureteral using polyacrylamide hydrogel.We performed single center, surgeon, prospective, off-label study hydrogel to treat reflux. All patients underwent subureteral double hydrodistention implantation technique...
Objective: The purposes of this multi-center study were to evaluate the rate infection stones and urine cultures patients with stones. Materials: Charts adulpatients urinary reviewed data on stone analyses collected. Results: In total, 1204 renal formers (RSFs) from 10 countries included (776 males, 428 females). Fifty-six (4.6%) had struvite highest frequency was observed in India (23%) Pakistan (18%). Lower rates reported Canada (2%), China (3%), Argentina Iraq Italy (3.5%) Poland...
A 63-year-old male, previously treated for a ureteral tumour by right-sided segmental ureterectomy and end-to-end anastomosis of segments, was referred to our clinic endoscopic follow-up. During his follow-up, he diagnosed with partial stricture which eventually progressed complete obstruction. the ureteroscopy, as stenotic segment did not allow passage an hydrophilic guidewire, antegrade-retrograde approach decided. On antegrade view, near-complete stenosis nephrostomy catheter (12 Fr)...
