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

Background: We aimed to compare the efficacy and safety of laparoscopic pyelolithotomy (LPL) versus percutaneous nephrolithotomy (PCNL) for treating renal stones larger than 2 cm.

Methods: We searched the PubMed, Embase, Web of Science, SinoMed, and Chinese National Knowledge Infrastructure databases for studies that compared the surgical outcomes of LPL and PCNL. We conducted a meta-analysis of the retrieved studies, expressed as weighted mean difference or risk ratios with 95% confidence intervals. 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.

Introduction: Urolithiasis in a kidney transplanted patient is an uncommon but complex urological complication. Its potential severity comes from its occurrence on a solitary kidney and on a field of immunosuppression. The aim of our study is to assess the incidence, characteristics and course of urolithiasis in our series. Read More

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

The aim of this article is to describe our technique of bilateral laparoscopic pyelolithotomy (LP) in a 54-year-old patient with bilateral large stones of which one is a staghorn stone (SS). The patient's legs were extended and spaced from each other; the table was tilted to the right and to the left in a way to use only five trocars for both sides. The calculi were delivered intact at the end of the procedure. 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

Introduction: Upper pole heminephrectomy (UHN) is performed for two main indications in children: ectopic ureterocele and duplication anomalies with upper pole ectopy, both in the context of a poorly functioning upper pole moiety. Current popular techniques for conducting UHN include laparoscopic (LPN) and robot-assisted laparoscopic (RAPN).

Objective: To evaluate outcomes following dorsal lumbotomy (DL), an open approach used historically for pyeloplasty and pyelolithotomy, and in which no clinical trials or exclusive case-series have been conducted for upper pole hemi-nephrectomy (UHN) in children. Read More

Laparoscopic pyelolithotomy has recently been introduced for renal stones. However, the use of this technique is limited in patients with history of extensive abdominal surgeries. We present a case of right side staghorn renal stone with history of abdominal open cystectomy who underwent laparoscopic pyelolithotomy with uneventful outcome. Read More

The gold standard for urologic management of large stone disease traditionally has been percutaneous nephrolithotomy (PCNL). An alternative to PCNL is robotic pyelolithotomy (RP), which continues to gain traction. This study is a retrospective review of ten cases performed over a 2 year period presenting operative outcomes for large stone disease treated with RP. Read More

The role of robotic assisted surgery in contemporary urolithiasis management is in its infancy. The mainstay in the management of renal tract calculi remains ureterorenoscopy (URS), extracorporeal shock wave lithotripsy (ESWL) and percutaneous nephrolithotomy (PCNL). However, in rare clinical circumstances, such as large impacted pelvic and ureteric calculi, endo-urological techniques may not be adequate. Read More
