Spontaneous rupture of the ureter is an uncommon condition defined by non-traumatic extravasation of urine. Causative factors leading to rupture include urinary calculi, malignancies, instrumentation or trauma. Ureteral rupture can lead to numerous complications, including abscess formation, urinomas, and urosepsis. Minimal literature is available regarding spontaneous ureteral perforation, especially at the ureteropelvic junction. We present a rare case of spontaneous perforation of the ureter at the ureteropelvic junction caused by an undiagnosed non-compliant bladder...

Yuyi Yeow, Yew-Lam Chong
Xanthogranulomatous pyelonephritis (XGPN) is a rare form of chronic pyelonephritis with progressive loss of renal function. Commonly, obstructing urinary calculi are seen. It is difficult to differentiate between XGPN and malignancy in many cases, and the diagnosis is usually only confirmed post-operatively upon histopathological examination of the specimen. Surgical treatment is often the main treatment modality due to suspicion for malignancy. Here, we present a case of XGPN that presented with abdominal distension, which was eventually discovered to be due to a preperitoneal abscess...

OBJECTIVE: While routine renal imaging following ureteroscopy for urinary calculi has been recommended to screen for asymptomatic "silent" obstruction, the rate of silent obstruction following percutaneous nephrolithotomy (PCNL) remains poorly defined, and no consensus recommendations exist on routine postoperative imaging. At our institution, we sought to assess the incidence of silent hydronephrosis (SH), as a screen for obstruction, following PCNL. METHODS: The records of all 162 patients who met study inclusion criteria were reviewed...

A twenty-eight-year-old female with a history of suprapubic pain and recurrent urinary tract infections presents for urology referral with a kidney, ureter, and bladder radiograph showing a 4.4 cm bladder calculus and 6.5 cm distal left ureteral stone. She underwent effective cystolitholapaxy of the bladder stone. Endourologic attempt (left ureteroscopy) was unsuccessful because of ureteral stone burden. Findings at ureteroscopy revealed a duplicated system on the left with the lower pole moiety joining just proximal to the ureteral orifice...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) has been adopted for pyelo-calyceal stones treatment in pediatric patients, starting from the 90's. Very recently, miniaturization of endoscopic instruments allowed less invasive procedures with low complication rate. We reviewed our experience on upper tract stone treatment utilizing two different percutaneous accesses, focusing on the recent new miniaturized devices offered for pediatric renal stones. METHODS: Patients presenting upper tract urinary stones observed from January 2011 to December 2015 and treated by percutaneous renal access were prospectively evaluated: age, sex, metabolic issues, associated abnormalities, treatment modalities, hospital stay and complication rate were recorded in a specific database...

BACKGROUND: In contrast to adult patients, a relatively large number of open surgical procedures are still needed in the treatment of urolithiasis in children. Since almost all open surgical techniques may be reproduced by minimal access surgery (MAS), there is a rationale to apply the latter in the management of pediatric urolithiasis. Our study aimed to assess the feasibility and outcome of MAS in the treatment of pediatric urinary calculi. METHODS: The charts of patients with urolithiasis submitted to MAS between 1994 and 2007 were retrospectively reviewed...

BACKGROUND AND OBJECTIVES: Holmium laser lithotripsy is the gold standard for intracorporeal fragmentation of urinary calculi. Usually, a visible beam is superimposed on the IR treatment laser as an aiming beam to guide the surgeon. In vitro tests showed that this aiming beam (532 nm, power <1 mW) excites strong fluorescence on human calculi. Tissue, in contrast, emitted much weaker fluorescence. If this is verified in vivo, the fluorescence signal induced by the aiming beam could be used to implement a feedback loop, preventing the Holmium laser being fired on tissue...

OBJECTIVES: Urinary calculi rarely occur in renal transplant. However, because of peculiarities shown with renal allografts, a prudent approach is necessary to prevent further complications or even graft failure. There are no well-established guidelines for uro?ithiasis in renal grafts regarding adequate therapy selection. In the present article, different therapeutic interventions are discussed, including in 1 case a pyelovesicostomy as an uncommon intervention. MATERIALS AND METHODS: We retrospectively reviewed data of 1115 patients who underwent renal transplant between January 2002 and December 2014 for urolithiasis in different databases...

Urinary calculi are being recognized more frequently in children and the urinary bladder is the most common site for stone formation in the lower urinary tract. Bladder calculi are grouped into three basic categories: primary idiopathic/endemic, secondary, and migrant. The incidence of vesical calculi has declined significantly in the last 70 years in developed nations owing to improvements in nutrition and socioeconomic conditions, but it is still high in developing nations. Primary idiopathic/endemic bladder calculi typically occur in children, in the absence of urinary tract infection (UTI), urinary stasis, or foreign body, and diet lacking in animal proteins is the major contributor factor...

Vincent Frochot, Michel Daudon
Crystalluria is a marker of urine supersaturation with substances deriving from metabolic disorders, inherited diseases or drugs. The investigation of crystalluria must be done according to a protocol which includes the delivery to the laboratory of a proper urine sample, the use of a microscope equipped with polarized light, the accurate knowledge of urine pH, and a comprehensive examination of the crystals, which is based on their identification, quantification and size measurement. For unusual crystals, infrared spectroscopy may also be needed...

BACKGROUND: Controversy remains on the superiority of combination therapy over monotherapy on ureteral stent-related symptoms (SRSs). We tend to explore if there is a necessity of combination therapy. METHODS: One hundred cases of unilateral upper urinary tract calculi with stent insertion (pre and post flexible ureteroscopy) were randomized into 4 groups, given non-treatment, solifenacin, tamsulosin or combination respectively. Eight times of follow-ups were given after each insertion...

Despite high prevalence of upper urinary tract calculi (UUTC), there are few studies regarding patterns of care in Asian populations. We investigated treatment patterns and time trends in patients with newly diagnosed UUTC in Korea using the National Health Insurance database that includes de-identified claims from a random 2% sample of the entire population (> 1 million people). A total of 14,282 patients who received active treatments, including shock wave lithotripsy (SWL), ureteroscopic surgery (URS), percutaneous nephrolithotomy (PNL), and uretero/pyelolithotomy (UPL), for newly diagnosed UUTC between 2003 and 2013 were included...

The objective of the study is to identify factors predicting development of pyonephrosis in patients of renal calculus disease (RCD), as this knowledge is largely unknown. Patients of RCD without pyonephrosis (Group 1) or with pyonephrosis (Group 2) presenting between December 2013 and November 2015 were evaluated. All patients of RCD who had undergone either percutaneous nephrostomy (PCN) or surgical management (percutaneous nephrolithotomy/pyelolithotomy/nephrectomy) were included. Patients treated conservatively, by extracorporeal shock-wave lithotripsy and patients of bilateral RCD were excluded...

Alkaptonuria is a rare autosomal recessive disorder of tyrosine metabolism. Deficiency of homogentisate 1,2 dioxygenase results in accumulation of oxidized homogentisic acid in the connective tissues of the skin, eyes and ears, musculoskeletal system, and cardiac valves, and in urolithiasis. Excretion of excessive homogentisic acid in urine causes dark-colored urine on exposure to air. We present a case of alkaptonuria with multiple system involvement, who presented with lower urinary tract symptoms secondary to vesical and prostatic calculi...

INTRODUCTION: Nephrolitiasis, once considered an adult disease, has become increasingly prevalent in children, with na increase from 6% to 10 % annually in past 25 years. Kidney stones in pediatric population can result from metabolic diseases in up to 50% of children affected. Other factors associated with litiasis are infection, dietary factors, and anatomic malformations of urinary tract. Standard treatment procedures for pediatric population are similar to adult population. Extracorporeal shock wave lithotripsy (ESWL), ureterorenoscopy (URS), percutaneous nepfrolithotomy (PCNL), as well as laparoscopic and retroperitoneoscopic approaches can be indicated in selected cases...
