Introduction: The aim of this article was to compare retrograde intrarenal surgery (RIRS), antegrade ureterorenoscopy (URS), and laparoscopic ureterolithotomy (LU) for impacted proximal ureter stones larger than 1.5 cm in terms of operative data, success, complications, auxiliary treatment rates, and visual analog scale (VAS) scores.

Material And Methods: Medical records of patients undergoing RIRS, antegrade URS, or LU were retrospectively reviewed. Read More

Purpose: With the improvement of minimally invasive urology procedures, open surgical interventions are less common to treat ureteral calculus. Laparoscopic ureterolithotomy (LU) indications are large multiple and/or impacted ureteral calculus that may not be treated with shock-wave lithotripsy or ureterorenoscopy approaches. The aim of our study was to investigate the feasibility and safety of stentless LU in elderly patients. Read More

Urinary stones are a common health problem, necessitating frequent outpatient visits and hospital admissions. Ureteric stones demand special attention, given their propensity for upstream hydroureteronephrosis and loss of renal function. They are usually predisposed by diverse anatomical, functional or metabolic abnormalities of the urinary tract and have an early symptomatic presentation. Read More

Background: The optimal treatment for large impacted proximal ureteral stones remains controversial. The aim of this study was to evaluate the efficacy, safety, and potential complications of mini-percutaneous nephrolithotomy (MPCNL) and retroperitoneal laparoscopic ureterolithotomy (RPLU) in the treatment of impacted proximal ureteral stones with size greater than 15 mm.

Methods: A total of 268 patients with impacted proximal ureteral stones greater than 15 mm who received MPCNL or RPLU procedures were enrolled consecutively between January 2014 and January 2019. Read More

This collection includes some unusual cases and how they were diagnosed and treated. Case 1: A case of a patient with primary hyperthyroidism presenting with a submucosal ureteral stone after endoscopic lithotripsy was described. After multiple endoscopic treatment, the stone was successfully removed by open ureterolithotomy recovering ureteral patency and normal renal function. Read More

Introduction This study was done to evaluate our experience of combining a retroperitoneal laparoscopic urological operation with other transperitoneal laparoscopic operations. Materials and methods We present a retrospective study of a series of 20 cases of retroperitoneal laparoscopic urological surgeries combined with at least one transperitoneal laparoscopic procedures, performed by a senior minimally invasive surgeon, between March 2013 and August 2020. We have excluded three patients where either of the procedures required conversion to open surgery. Read More

Primary obstructed megaureter (POM) usually refers to primary dilated ureters in which vesicoureteral reflux and other secondary causes of lower ureteral obstruction have been ruled out. We herein present a case of obstructed megaureter with a dilated saccular lower end representing an ureterocele and concomitant multiple multifaceted stones almost completely filling the dilated tortuous ureter of a normally functioning and excreting kidney. Our index case was a 45-year-old lady with intermittent right flank pain for a year with acute colic since a week. Read More

Ureteroceles containing stones present as a unique challenge to the urologist. When a calculus has to be removed from within the ureterocele, a large opening leads to vesicoureteral reflux (VUR), which may result in recurrent infections and renal parenchymal damage. We present a case of a 13-mm stone in the ureterocele in an 11-year-old boy. Read More

Pediatric urolithiasis may coexist with congenital urinary tract abnormalities, complicating conventional methods of stone treatment. Here, we present an effective case of robot-assisted laparoscopy and simultaneous ureteropyeloscopy for the definitive management of pediatric urolithiasis complicated by a congenital ureteral stricture. A 3-year-old girl presented to clinic with an outside noncontrast CT scan showing two 6-7 mm nonobstructing calculi in a mildly distended upper pole moiety of a duplex left kidney. Read More

Ureteric stone disease is increasing, especially in developed countries, and present in different ages with various patterns; it has many treatment modalities and outcomes. Ureteric stones are usually small and symptomatic but maybe large, asymptomatic associates with totally distracted kidneys. However, some ureteral calculi show silent progression to reach a large size without underlying anatomic abnormalities. Read More

Rationale: The indwelling ureteral stents is a common procedure in routine urological practice. The double-J (D-J) stent is the most common type of stents used and is indicated mainly for short-term urinary drainage and prevention of obstruction and infection. However, prolonged indwelling stents may result in disastrous complications, such as hematuria, infection, encrustation, and stone formation. Read More

Introduction: We evaluated the efficacy and safety of laparoscopic ureterolithotomy (LPU) for the treatment of large proximal ureteric stone.

Methods: A retrospective multicenter analysis for patients with solitary impacted proximal ureteric stone ≥15 mm who underwent LPU from 2016 to 2019 was performed. Primary outcome was to estimate the stone-free rate (SFR). Read More

Objectives: To develop an evidence base to guide clinicians treating adults with large proximal ureteral stones (LPUS) greater than 10 mm.

Methods: A systematic search of PubMed, EMBASE, and Cochrane Library was conducted to identify randomized controlled trials (RCT) concerning different LPUS management techniques including laparoscopic ureterolithotomy (LU), percutaneous nephrolithotomy (PCNL) and ureteroscopic lithotripsy (URL) up until March 2020. We followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement when searching and determining inclusion. Read More

To conduct a prospective and randomized controlled trial comparing contemporaneous transabdominal rigid ureteroscopy (TRU) with postoperative extracorporeal shockwave lithotripsy (SWL) in the management of migrated or residual stones during laparoscopic pyelolithotomy and ureterolithotomy in kidneys with either intrinsic or extrinsic abnormalities. From February 2016 to December 2019, 45 patients with migrated or residual stones following laparoscopic pyelolithotomy and ureterolithotomy were accrued and randomly divided into two groups. These patients all had either urinary tract obstruction distal to the stone or concomitant ipsilateral intrinsic or extrinsic pathology requiring laparoscopic intervention. Read More

Purpose: Various surgical options are available for large proximal ureteral stones, such as extracorporeal shock wave lithotripsy (ESWL), ureteroscopic lithotripsy (URSL), percutaneous nephrolithotomy (PCNL) and laparoscopic ureterolithotomy (LU). However, the best option remains controversial. Therefore, we conducted a network meta-analysis comparing various surgical treatments for proximal ureteral stones ≥10mm to address current research deficiencies. Read More

Managing patient having multiple large ureteric calculi at different locations in ureter with minimal invasive surgery is always a challenge for the surgeon. We hereby present the case report of ureteroscopy assisted laparoscopic ureterolithotomy for multiple large ureteric calculi in proximal and distal ureter in a young female. In this unique and novel method ureteroscopy and laparoscopy was done simultaneously over the patient using two camera units and two surgeons. Read More

Objectives: Patients with autosomal dominant polycystic kidney disease (ADPKD) showed relatively high incidence of urinary stones. Enlarged kidneys occupied by cysts could make the stone-removal surgery relatively difficult. This study aimed to compare the efficacy and safety of retroperitoneal laparoscopic ureterolithotomy (RPLU), flexible ureteroscopic lithotripsy (FURL) and percutaneous nephrolithotomy (PCNL) in the ADPKD patients with upper urinary stones.

Background: Urolithiasis is a clinically common benign disease in urology. Surgical treatments that are widely used in urolithiasis are percutaneous nephrolithotomy, rigid/flexible ureteroscopy, laparoscopic surgery, and endoscopic combined intrarenal surgery. The da Vinci surgical system is rarely used in the treatment of urolithiasis. Read More
