Background: Hem-o-Lok clips (HOLCs) are widely used in minimal access urological operations due to the advantage of vascular control and suture stabilization. In rare cases, however, they can develop problems themselves. Migration of HOLCs into the collecting system is a fairly rare complication after laparoscopic pyelolithotomy. Read More

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

Background: Robotic-assisted surgeries have gradually become the standard of care for many procedures, especially in the field of urology. Despite the widespread use of robotic assistance in surgeries, data on its postoperative complications are extremely limited. We detail a rare presentation of fulminant Clostridium difficile colitis requiring surgical intervention in a patient with a solitary ectopic pelvic kidney who underwent a robotic-assisted pyelolithotomy.

Supernumerary kidney is a rare anomaly of number where commonly a third extra kidney exists with its own collecting system, blood supply, and encapsulated parenchyma. However, an extremely rare and unique diagnosis of bilateral supernumerary kidneys is also reported in few instances where two extra kidneys exist on each side of the body. Parenchymal fusion and the presence of good excretory function make the supernumerary kidneys even rarer as many of the reported cases are rudimentary organs. Read More

Introduction: The aim of this systematic review and meta-analysis was to provide an updated comparison between the currently available minimally invasive approaches (PCNL, laparoscopic [LP] and robotic pyelolithotomy [RP]) for the management of large renal stones.

Evidence Acquisition: An electronic search of the current literature was conducted through the Medline and NCBI PubMed, Embase, Scopus and Cochrane Collaboration Central Register of Controlled Clinical Trials databases in March 2021. Studies about minimally-invasive treatment for kidney stones were considered. Read More

Management of urolithiasis in an ectopic pelvic kidney is challenging and laparoscopic pyelolithotomy and laparoscopy-guided percutaneous nephrolithotomy (PCNL) are commonly favored options. We report a case of ultrasound-guided supine mini-PCNL in ectopic pelvic kidney in an adolescent female. Complete stone clearance was achieved with an uneventful postoperative period. Read More

Staghorn calculi (SC) are associated with high morbidity and mortality; therefore, meticulous planning is required to minimize complications. In this case report, we will discuss the management of a giant right-sided SC (~ 8 cm in diameter), which was incidentally found in a 40-year-old male, who presented with left-sided renal colic symptoms with no associated renal impairment. This case was further complicated by multiple smaller calculi surrounding the giant SC. Read More

A retro-renal colon (RRC) is a rare but important anatomical variant to consider when planning percutaneous stone surgery. CT scanning of the abdomen is critical to detect this and to plan the surgical approach to avoid injury to the colon. In this case report, a 38-year-old woman with large obstructing bilateral symptomatic renal stones was found to have a left retro-renal colon on image review prior to left percutaneous nephrolithotomy.

This manuscript provides an overview of the available literature about unilateral combination of nephrolithiasis and renal tumor. Analysis of publications has shown that ipsilateral staghorn calculus and kidney tumors are an extremely rare combination. The majority of these infrequent papers describe case reports where the method of treating such patients is limited by the capabilities and competence of the surgeon or clinic. Read More

Renal ectopia is a developmental anomaly with pelvic kidney being the commonest location (55%). The incidence of uretero-pelvis junction (UPJ) obstruction, nephrolithiasis, and reflux are higher in ectopic kidneys than their counterparts. We herein report a case of left ectopic pelvic kidney with large stone associated with UPJ narrowing managed successfully simultaneously with laparoscopic transmesocolic pyelolithotomy and pyeloplasty in a 45-year female.

While spillage of intraperitoneal gallstones has been reported frequently in the literature, spilled renal stones after urologic intervention is rare. The dropped renal stones may mimic peritoneal carcinomatosis (PC) on imaging, causing concern and potentially leading to unnecessary diagnostic workup. Additionally, these dropped stones may cause surrounding inflammation, potentially leading to the formation of adhesions or an intra-abdominal abscess. Read More

Crossed fused renal ectopia (CFRE) is a rare fusion anomaly of the kidneys, with a predisposition to calculus disease. Management of renal calculi in CFRE is not standardized because of paucity of literature. We managed a 32-year-old man with left to right CFRE with multiple stones in both the kidneys by percutaneous nephrolithotomy for the right moiety and laparoscopic pyelolithotomy for the crossed moiety.

Management of renal calculi in a patient with kidney malrotation can be difficult because of complexity and alteration of collecting system anatomy. Pyelolithotomy, whether open, laparoscopic, or robotic, has been shown to be an effective method of stone removal in this patient population; however, it is not always ideal because of its invasiveness and increased morbidity. Ideally, a percutaneous approach may be less invasive, and if feasible, it can optimize patient safety and stone-free status. Read More
