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)...

INTRODUCTION: The Moses technology of the holmium laser has been shown to decrease retropulsion in the ureter and procedural time in kidney stones during laser lithotripsy. Theoretically, these improvements could lead to cost savings for the patient. MATERIALS AND METHODS: All patients with total laser energy data recorded who underwent ureteroscopy with laser lithotripsy by a single surgeon at a tertiary care center were included. Total lasing time was calculated from the total laser energy...

Objectives: To review the clinicopathologic features of five patients with epithelioid trophoblastic tumor (ETT). Methods: Characteristics of patients diagnosed with ETT in 2000 to 2012 were reviewed. Results: Among 190 patients with gestational trophoblastic neoplasia (GTN), two had pure ETT and three had mixed ETT and choriocarcinoma. The median age was 32.5 years. All the patients had localized disease in the uterus. One patient with pure ETT had a recurrence in the ureter 6 years after the initial treatment...

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 evaluate the utility of hydroureter (HU) to identify high-grade vesico-ureteric reflux (VUR) in patients with high-grade postnatal hydronephrosis (PH). Patients and methods: We retrospectively reviewed patients' charts that had antenatal hydronephrosis from 2008 to 2014. Patients were excluded if they presented with febrile urinary tract infection (fUTI), neurogenic bladder, posterior urethral valve, multi-cystic dysplastic kidney, and multiple congenital malformations...

STUDY OBJECTIVE: To present a case of a cesarean scar ectopic pregnancy treated by laparoscopic resection followed by isthmocele repair. DESIGN: Case report SETTINGS: University Gynecology Clinic of the Emergency Clinical City Hospital Timișoara, România. BACKGROUND: Cesarean scar pregnancy is a rare form of ectopic pregnancy. In the last years its prevalence has risen due to the increasing number of cesarean section. An early diagnosis can lead to an early management decreasing the risk of life-threatening complication such as uterine rupture and massive haemorrhage...

OBJECTIVES: To evaluate the association of positive margins in the intraoperative biopsy during radical cystectomy (RC) with the risk of recurrence in the uretero-ileal anastomosis or upper urinary tract (UUT), and identify potential risk factors for positive ureteral margins. METHODS: A retrospective, descriptive study was performed in patients treated with radical cystectomy due to transitional cell carcinoma (TCC), who underwent a cold biopsy of the ureteral margin at the time of cystectomy...

INTRODUCTION: ureteral stump syndrome is defined as a recurrent urinary infection, low abdominal pain and haematuria in patients with a history of nephrectomy. Its incidence is low and the symptoms are non-specific. The aim of our paper was to present our results with endoscopic treatment of symptomatic ureteral remnants. MATERIAL AND METHODS: We performed a retrospective study of patients with ureteral remnant syndrome after nephrectomy treated in our centre between 2004 and 2015...

To investigate the effect of fluorofenidone on renal interstitial fibrosis in rats with unilateral ureteral obstruction (UUO) and to observe the effect of fluorofenidone on the expressions of collagen type I (Col I), collagen type III (Col III), α-smooth muscle actin (α-SMA), connective tissue growth factor (CTGF), platelet derived growth factor (PDGF) in the renal tissues of UUO rats.
 Methods: Male Sprague-Dawley (SD) rats were randomly divided into a sham-operated group, a UUO group, and a flurofenidone group (n=5)...

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...

BACKGROUND: It is extremely important to not only address the short-term success following endoscopic correction of vesicoureteral reflux (VUR) but also the long-term efficacy and safety of the tissue augmenting substance utilized for endoscopic correction. OBJECTIVE: This study retrospectively evaluated all cases of ureterovesical junction (UVJ) obstruction following endoscopic treatment of VUR over the last 5 years utilizing two tissue augmenting substances, with special emphasis on the safety of Vantris® , and performed clinical and histological review of these patients...

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...

OBJECTIVES: To determine whether short-term stenting using an external ureter catheter following ureterorenoscopic stone extraction provides a better outcome in comparison to double-J stent ureteral stenting. METHODS: Between August 2014 and August 2015, 141 patients initially managed with a double-J stent insertion were prospectively randomized to ureter catheter for 6 h vs double-J stent insertion for 5 days after stone extraction via ureteroscopy retrograde surgery (including flexible ureteroscopy retrograde surgery) in a single academic center...

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...
