Rationale: Double-J stents (DJSs) are urologic devices widely used for urinary tract obstruction treatment. Perinephric abscess is a condition with purulent accumulation resulting from urinary tract infection retained between the renal capsule and Gerota's fascia. Emphysematous urinary tract infection in patients with a forgotten DJS is extremely rare. Read More

Trans-peritoneal laparoscopic ureterolithotomy is a well-established minimally invasive procedure for management of large impacted ureteric stones since the last 3 decades. We present a case of a 51-year old gentleman, who presented with bilateral large upper ureteric calculi with obstructive uropathy and azotemia, managed successfully with bilateral synchronous 3-port trans-peritoneal laparoscopic ureterolithotomy, and to our knowledge is the first such case to be reported in literature.

With the rising incidence of urinary stone disease, web searches for stone treatments are increasing. Google Trends (GT) data over a 10-year period and during the COVID-19 pandemic were used to investigate the trend variations for the most popular minimally invasive stone therapies based on time and region. GT can create a line graph that shows how interest in various territories has risen or decreased over time. Read More

Introduction: Incidence of pediatric urolithiasis has increased over the last few decades. Procedures such as extracorporeal short wave lithotripsy, percutaneous nephrolithotripsy, and ureterorenoscopic lithotripsy are not widely available for pediatric age group in many developing countries. It is desirable that advantages of minimally invasive surgery be offered to selected cases with urolithiasis. Read More

Medicine (Baltimore) 2021 Jul;100(28):e26655

Department of Urology, China Medical University Hospital, Taichung, Taiwan.

Rationale: Concurrent kidney and ureteral stones are always complicated and a clinical challenge. Improvements in endoscopic equipment have led to the widespread adoption of retrograde intrarenal surgery, which has a good stone clearance rate. On the other hand, laparoscopic ureterolithotomy (LUL) has been reported to be non-inferior to retrograde flexible ureteroscopy in stone-free rate and the need for axillary procedures, and to have a significantly lower rate of post-operative sepsis compared to retrograde flexible ureteroscopy.

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

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

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
