Focal Xanthogranulomatous pyelonephritis is a rare chronic inflammatory condition of kidneys which usually is associated with postrenal obstruction or renal stone leading to chronic bacterial infection and eventually chronic glomerular inflammation. About 90% of cases are of the diffuse type and associated with staghorn renal calculi. The case presented in this paper is of the focal type in a 58-year-old diabetic female. Interestingly she did not have symptoms or laboratory presentation of chronic renal bacterial infection except for elevated ESR...

PURPOSE: Percutaneous nephrolithotomy (PCNL) is the preferred surgical treatment for staghorn stones. Two approaches are commonly employed to gain access into the collecting system which consists of either an upper pole (UP) approach or lower pole (LP) approach. However, opinions vary on which approach offers the best access and outcome. In this study, we aim to challenge the traditional paradigm that staghorn stones are most effectively treated through a prone UP approach. We herein report our institutional experience using a prone LP access in PCNL for patients with complete staghorn stones...

Owing to the fragile kidney and relative small collecting system of pediatric patients, urologists were always reluctant to treat pediatric urolithiasis with PCNL. Here we conduct a study to assess the effectiveness and safety of pediatric patients with renal calculi <6 years.A total of 88 pediatric patients (99 kidney units) <6 years underwent the ultrasound (US)-guided minimally invasive percutaneous nephrolithotomy in our institute from March 2006 to April 2016. The mean age was 30.9 months (range, 7-72 months)...

In this study, we aimed to determine factors affecting the success rate of percutaneous nephrolithotomy (PNL) in children. The series consisted of 41 consecutive children operated on by the same surgical team for renal calculi with PNL between June 2002 and May 2015 in our institution. A single calyx or pelvic stone was described as simple, while calculi located in more than one location (calyx and pelvis or more than one calices) or staghorn stones were described as complex. The procedure was deemed successful if the patient was completely stone-free (SF) or had residual fragments <4 mm...

BACKGROUND: Minimally invasive procedures have become the standard option for treatment of urinary stones; the use of more invasive techniques is not a common practice currently. This emergent technology is not always available and laparoscopy is the alternative option. There are few reports of laparoscopic management for urinary lithiasis in pediatric patients. This study is about the use of laparoscopic surgery combined with pyeloscopy as a feasible first-line treatment for pediatric urolithiasis in renal and proximal ureteral locations...

A staghorn calculus is a calculus accommodating the majority of a renal calyx extending into the renal pelvis. A conservative approach to its treatment may lead to high morbidity and mortality rates. Such morbidity usually manifests with renal failure, obstructed upper urinary tractand/or life-threatening sepsis. Prostatic abscesses have never been associated with staghorn calculi in the literature. We report a case of a 70-year-old man who presented with sepsis, which was found to originate from a complex prostatic abscess...

Large staghorn calculi in unascended pelvic kidneys and in normally located kidneys with anatomy unsuitable for percutaneous nephrolithotomy have to be treated via pyelolithotomy. When performed laparoscopically, the extraction of these staghorn calculi, without extending skin incision at the port site is challenging. We describe the successful use of laparoscopic laser lithotripsy, intracorporeally, with the entrapped calculus inside the endocatch bag, for fragmentation and retrieval without extension of skin incision...

Background: Percutaneous nephrolithotomy (PCNL) is a procedure typically performed under general anesthesia (GA); however, many patients might be considered unfit for GA and locoregional anesthesia is their only chance to have the procedure done. Case Presentation: A 60-year-old Middle-Eastern female with end-stage lung disease underwent evaluation for lung transplant; she was found to have severe restrictive pattern on steroid and continuous oxygen therapy, pulmonary hypertension with dilated right ventricle, chronic anemia, and asthma...

RELEVANCE: Management of patients with large and staghorn stones of a solitary kidney is widely debated among urologists and has not been sufficiently investigated, which determined the relevance of this study. MATERIALS AND METHODS: The study comprised 80 patients with large (>20 mm) and staghorn stones of an anatomically or functionally solitary kidney. Of them, 58 patients underwent percutaneous nephrolithotripsy (PNL), and 22 had open surgery. The criterion of the treatment effectiveness was the complete stone clearance or small residual fragments sized less than 3 mm...

The aim of the present study was to summarize the management of upper urinary tract calculi in crossed fused renal ectopia (CFRE). Two patients were retrospectively studied in Xiangya Hospital (Changsha, China) and all relevant literature published in English between 1996 and 2016 was reviewed. All patients, including those reported in the literature, were characterized by age, sex, manifestation, therapy history, ectopic side, stone location, surgery and outcome. The patients had a mean age of 42.3±18.5 years, a male: Female ratio of 5:4 and the ratio of renal ectopic side was 9:8 (left:right)...

OBJECTIVE: To evaluate the effect of prepuncture on the double-tract percutaneous nephrolithotomy (PCNL) under ultrasound guidance for renal staghorn calculi. METHOD: Double-tract or even multi-tract is necessary for the treatment of staghorn calculi. However, intraoperative injury, exudation, bleeding, and influence of original tract might lead to difficulty in second puncture, thus prolonging operating time, and even lead to puncture failure. We retrospectively reviewed the records of 178 patients with renal staghorn calculi who received double-tract PCNL in our department...
