Comparing extracorporeal shock wave lithotripsy and ureteroscopy laser lithotripsy for treatment of urinary stones smaller than 2 cm: a cost-utility …

2021

[EN] Purpose To analyze the efficiency and cost-utility profile of ureteroscopy versus shock wave lithotripsy for treatment of reno-ureteral stones smaller than 2 cm. Methods Patients treated for urinary stones smaller than 2 cm were included in this study (n = 750) and divided into two groups based on technique of treatment. To assess the cost-utility profile a sample of 48 patients (50% of each group) was evaluated. Quality of life survey (Euroqol 5QD-3L) before-after treatment was applied, Markov model was designed to calculate quality of life in each status of the patients (stone or stone-free with and without double-J stent) and to estimate the incremental cost-utility. Monte carlo sim…

Stone-Free Rate after Treating Kidney Stones Exceeding 10 mm via Flexible Ureteroscopy: Can Endoscopic Assessment Replace Low-Dose Computed Tomograph…

2019

<b><i>Introduction:</i></b> It is unclear whether endoscopic assessment of the stone-free rate after flexible ureteroscopy (fURS) is as effective as assessment with low-dose computed tomography (CT) scan. <b><i>Methods:</i></b> Prospective documentation of patients with kidney stones > 10 mm diameter from 2 different centers (Freiburg, Regensburg), who underwent fURS and were declared to be endoscopically completely stone-free. Low-dose CT control performed 4–8 weeks postoperatively. <b><i>Results/Conclusion:</i></b> Thirty-eight patients were treated between October 2015 and August 2016 (12 F, 26 M). Average a…

Treatment of Bladder Stones in Adults and Children: A Systematic Review and Meta-analysis on Behalf of the European Association of Urology Urolithias…

2019

Bladder stones (BS) constitute 5% of urinary stones. Currently, there is no systematic review of their treatment.To assess the efficacy (primary outcome: stone-free rate [SFR]) and morbidity of BS treatments.This systematic review was conducted in accordance with the European Association of Urology Guidelines Office. Database searches (1970-2019) were screened, abstracted, and assessed for risk of bias for comparative randomised controlled trials (RCTs) and nonrandomised studies (NRSs) with ≥10 patients per group. Quality of evidence (QoE) was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool.A total of 2742 abstracts and 59 full-text article…

Comparative analysis of direct and indirect costs of two minimally invasive techniques for the treatment of renal/ureteral calculi smaller than 2 cm

2020

[EN] Objective: To perform a comparative analysis of indirect and direct costs of two minimally invasive techniques (extracorporeal shock wave lithotripsy (ESWL) vs. ureteroscopy with holmium laser (URS/RIRS)) for the treatment of renal/ureteral calculi smaller than 2 cm. Material and methods: Prospective, comparative, non-randomized study of 84 patients treated for kidney stones smaller than 2 cm between January and December 2016. Of these, 38 (45.67%) were treated with ESWL (18 renal lithiasis and 20 ureteral lithiasis) and 46 (54.32%) with URS/RIRS (22 renal lithiasis and 24 ureteral lithiasis). A total of 19 (41.3%) patients in the URS/RIRS group and 15 (39.5%) patients in the ESWL grou…

Local Shock-Wave Lithotripsy of Distal Ureteral Calculi

1988

Abstract Since the initiation of the clinical trial utilizing a second-generation lithotripor (Lithostar, Siemens, Erlangen, FRG), 96 patients with distal ureteral calculi (i.e. calculi below the pelvic brim) underwent local shock-wave lithotripsy. Routine treatment was conducted under intravenous sedation and light analgesia only. Complete stone disintegration was achieved in 84 patients (87.5%), 11 requiring two sessions and 1 patient, three. In 7 patients ureteroscopy became necessary after unsuccessful local shock-wave treatment. In 2 of these patients a 9-french flexible ureteroscope and the Storz Q-switched neodymium-YAG laser was used for stone disintegration. In 3 cases loop extract…

Elective segmental ureterectomy for transitional cell carcinoma of the ureter: Long-term follow-up in a series of 73 patients

2012

What's known on the subject? and What does the study add? Upper Urinary Tract (UUT) Transitional Cell Carcinoma (TCC) is an uncommon disease and represents approximately 5% of all urothelial carcinomas. We report our series on 73 patients treated with Kidney Sparing Surgery for UUT TCC. Good results have been achieved in terms of oncological outcome comparing this conservative approach to the radical nephrourectomy. OBJECTIVES: • To report the long-term oncological outcome in patients with transitional cell carcinoma of the ureter electively treated with kidney-sparing surgery. • To compare our data with the few series reported in the literature. PATIENTS AND METHODS: • We considered 73 pat…

Two-stage transperineal management of posterior urethral strictures or bladder neck contractures associated with urinary incontinence after prostate …

2007

Objectives: The treatment of posterior urethral strictures or bladder neck contracture associated with severe urinary incontinence after prostate surgery and failure of endoscopic treatments is controversial. We report our experience with a transperineal approach in two steps: end-to-end urethroplasty/anastomosis and subsequent artificial urinary sphincter implantation.Methods: Between September 2001 and January 2005, we observed six patients (58-68 yr old), with a combination of severe urinary incontinence and posterior urethral stricture with anastomotic bladder neck contracture after prostate surgery. In all cases, repeated endoscopic treatments of the strictures failed. The patients und…

Ureteral Stones: Shockwave Lithotripsy or Ureteroscopy, Which is Best?

2021

Background Renal stone disease is common and can cause emergency presentation with acute pain due to ureteric colic. International guidelines have stated the need for a multicentre randomised controlled trial (RCT) to determine whether a non-invasive outpatient (shockwave lithotripsy [SWL]) or surgical (ureteroscopy [URS]) intervention should be the first-line treatment for those needing active intervention. This has implications for shaping clinical pathways. Objective To report a pragmatic multicentre non-inferiority RCT comparing SWL with URS. Design, setting, and participants This trial tested for non-inferiority of up to two sessions of SWL compared with URS as initial treatment for ur…
