INTRODUCTION: The duplex kidney is one of the most common congenital abnormalities of the urinary tract, and various surgical procedures exist for the management of this condition. Depending on the surgeon preferences, patients with duplex kidney may undergo heminephrectomy with ureterectomy using open or laparoscopic approach, uretero-cysto-anastomosis of the ectopic ureter or two ureters in a single block. Recently, there have been reports of inter-ureter anastomoses. Here we report our multicenter experience in open and laparoscopic uretero-ureteral anastomosis (UUA)...

The horseshoe kidney (HSK) is not an uncommon entity with an incidence of about 1 in 400 or 0.25% of the general population. It is also more commonly found in men as compared with women in a ratio of 2:1.An increased association of genitourinary anomalies have been found with HSK.Duplication of ureters occurs in 10% of HSKs. However, the association of HSK with single-system ectopic ureter is extremely rare. To our knowledge, no case with similar presentation has been reported in literature. Most cases of HSK with bilateral single ectopic ureters have been described...

OBJECTIVE: To report and visually demonstrate the feasibility of using indocyanine green (ICG) in endometriosis surgery and to discuss potential benefits. DESIGN: ICG fluorescent imaging has been validated to assess tissue perfusion with clinical use in many medical fields, including gynecology and digestive surgery, but has not described in endometriosis surgery for bowel assessment. To our knowledge, there is no validated, objective, intraoperative method to assess the vascularity of the operated bowel in endometriosis surgery, a potentially good indicator for postoperative fistula formation...

Lysosomal dysfunction is associated with a number of age-related pathologies that affect all organ systems. While much research has focused on neurodegenerative diseases and aging-induced changes in neurons, much less is known about the impact that aging has on lower urinary tract function. Our studies explored age-dependent changes in the content of endo-lysosomal organelles (i.e., multivesicular bodies, lysosomes, and the product of their fusion, endolysosomes) and age-induced effects on lysosomal degradation in the urothelium, the epithelial tissue that lines the inner surface of the bladder, ureters, and renal pelvis...

A 74-year-old man presented at our hospital with complaints of abdominal pain, nausea, and vomiting. He had undergone laparoscopic radical cystectomy and ileal conduit for urinary bladder cancer 1 month earlier. The patient had abdominal distention, resonant sounds on percussion, and diffuse abdominal tenderness without rebound or guarding. Abdominal CT revealed dilated jejunal loops herniated through a cord-like structure. Based on these findings, emergency surgery was performed, and intestinal dilatation into the space between the ureter, the ileal conduit, and the sacral bone was detected...

Background: The mortality rates for different cancers are no longer an efficient tool for making national policy. The purpose of this study were to quantify the lifetime risks, life expectancies (LEs) after diagnosis, expected years of life lost (EYLL), and lifetime health care expenditures for 19 major cancers in Taiwan. Methods: A total of 831,314 patients with 19 pathologically proven cancers were abstracted from the Taiwan Cancer Registry from 1998 to 2012. They were linked to the National Mortality Registry (1998-2014) and National Health Insurance reimbursement database (1998-2013) for survival and health care costs...

BACKGROUND: Overuse of computed tomography (CT) in the initial evaluation of children with upper urinary tract calculi (UUTC) has been well documented. Follow-up imaging patterns, however, remain undefined. Sequential imaging following an acute episode of UUTC represents additional opportunity for enacting good imaging stewardship, with the optimal goal to reduce unnecessary radiation exposure and cost while ensuring appropriate follow-up. OBJECTIVE: We explored nationwide imaging patterns for children following emergency department (ED) evaluations for UUTC, hypothesizing that initial imaging choice and complicated visits for UUTC increase the risk of follow-up CT scans...

BACKGROUND: Urolithiasis is a condition where crystalline mineral deposits (stones) form within the urinary tract. Urinary stones can be located in any part of the urinary tract. Affected children may present with abdominal pain, blood in the urine or signs of infection. Radiological evaluation is used to confirm the diagnosis, to assess the size of the stone, its location, and the degree of possible urinary obstruction. OBJECTIVES: To assess the effects of different medical and surgical interventions in the treatment of urinary tract stones of the kidney or ureter in children...
