BACKGROUND: Ureteral stents are commonly placed before colorectal resection to assist in identification of ureters and prevent injury. Acute kidney injury (AKI) is a common cause of morbidity and increased cost following colorectal surgery. Although previously associated with reflex anuria, prophylactic stents have not been found to increase AKI. We sought to determine the impact of ureteral stents on the incidence of AKI following colorectal surgery. METHODS: All patients undergoing colon or rectal resection at a single institution between 2005 and 2015 were reviewed using American College of Surgeons National Surgical Quality Improvement Program dataset...

A one-year-old intact male German shepherd dog was referred with a 3-month history of dysuria and pollakiuria. Physical examination revealed a large firm mass in the caudal abdomen. Findings from survey radiography, negative contrast cystography, computed tomographic (CT) retrograde positive contrast cystography, and CT excretory urography were consistent with a large urinary bladder diverticulum. An exploratory laparotomy revealed a normal wall appearance in the ventral compartment (true bladder) and marked thinning of the wall in the dorsal compartment (diverticulum)...

BACKGROUND: VAMP5 is a member of the SNARE protein family, which regulate the docking and fusion of membrane vesicles within cells. Previously, we reported ubiquitous expression of VAMP5 proteins in various organs except the brain and small intestine. However, the precise roles of VAMP5 in each organ remain unclear. To explore the roles of VAMP5 in vivo, we generated VAMP5 knockout (KO) mice. RESULTS: VAMP5 KO mice showed low birth rate and low body weight. KO embryos grew normally in the uterus, and tended to die around birth...

Intravesical recurrence (IVR) after RNU for UTUC is a frequent event, occurring in 20-50% of patients, mostly in the first postoperative year. Several retrospective studies have shown that predictors of IVR include clinical characteristics, surgical features and as well pathological characteristics (previous history of bladder cancer, pathological stage, lymph node involvement, cis, endoscopic distal ureter, etc.) management. Two prospective studies provide level I evidence for the safety and efficacy of intravesical single postoperative chemotherapy for patients treated with radical nephroureterectomy (RNU) for UTUC in order to prevent IVR...

The epithelial Wolffian duct (WD) inserts into the cloaca (primitive bladder) before metanephric kidney development, thereby establishing the initial plumbing for eventual joining of the ureters and bladder. Defects in this process cause common anomalies in the spectrum of congenital anomalies of the kidney and urinary tract (CAKUT). However, developmental, cellular, and molecular mechanisms of WD-cloaca fusion are poorly understood. Through systematic analysis of early WD tip development in mice, we discovered that a novel process of spatiotemporally regulated apoptosis in WD and cloaca was necessary for WD-cloaca fusion...

Miniaturization of ureteroscopy materials is intended to decrease tissue damage. However, tissue hypoxia and the gross and microscopic effects on tissue have not been adequately assessed. We compared the gross and microscopic effects of micro-ureteroscopy (m-URS) and conventional ureteroscopy (URS) on the urinary tract. We employed 14 pigs of the Large White race. URS was performed in one of the ureters with an 8/9.8 F ureteroscope, while a 4.85 F m-URS sheath was used in the contralateral ureter. Gross assessment of ureteral wall damage and ureteral orifice damage was performed...

BACKGROUND: The Post-ureteroscopic Lesion Scale (PULS) was designed as a standardized classification system for ureteral lesions after uretero(reno)scopy (URS). This study evaluates its routine use and a possible clinical impact based on a representative patient cohort. MATERIALS AND METHODS: Data of 307 patients in 14 German centers within the BUSTER project were used to test 3 hypotheses (H): PULS score shows a high interrater reliability (IRR) after independent assessment by urologic surgeon and assistance personnel (H1); PULS score is correlated with the frequency of postoperative complications during hospital stay (H2); post-URS stenting of the ureter is associated with higher PULS scores (H3)...

The renal artery pseudoaneurysm embody a rare vascular complication coming of percutaneous procedures, renal biopsy, nephrectomy, penetrating traumas and more rarely blunt traumas. The clinical can be vary according the patient, the haematuria is the symptom more commom. Is necessary a high level of clinical suspicion for your diagnosis, this can be elucidated by through complementary exams as the eco-color Doppler and the computed tomography scan (CT). This report is a case of a patient submitted a right percutaneous renal biopsy and that, after the procedure started with macroscopic haematuria, urinary tenesmus and hypogastric pain...

True metastatic ureteric lesions are exceptionally rare when sourced from any primary tumour. Primary prostatic cancer metastasis to the ureter is understandably even more atypical with very few cases reported in current literature. True intramural ureteric metastatic disease deposited from prostate cancer is an even rarer occurrence. We present a case of a man in his mid-60s with left-sided hydronephrosis in the setting of biochemical recurrence of Gleason 9 prostate cancer. Initially misdiagnosed as obstruction secondary to mass effect from a large trigonal lesion, subsequent investigation revealed solid intramural metastatic deposit of prostate primary tumour in the distal ureter...

Because of problems with vaginal meshes and high rate recurrences of native tissue repair, more and more surgeons treat pelvic organ prolapse performing laparoscopic sacrocolpopexy. This surgery requires skilled surgeons. The first step of sacrocolpopexy is the dissection of tissues in front of the sacral promontory to reach the anterior longitudinal ligament. Some complications can occur during this dissection and the attachment of the mesh. This place is dangerous for surgeons because of the proximity of vessels, nerves and ureters...

OBJECTIVE: To describe our ultrasound technique for confirming intraoperative, antegrade-placed ureteral stent position during laparoscopic pyeloplasty. BACKGROUND: Disadvantages of retrograde stent placement include the need to reposition the patient into and out of the lithotomy position. Antegrade stent placement can reduce procedure time but requires confirming appropriate distal placement into the bladder with cystoscopy, percutaneous drain placement, or instillation of methylthioninium chloride or indigo carmine...

The expression of aquaporins (AQPs) in the fetal porcine urinary tract and its relation to gestational age has not been established. Tissue samples from the renal pelvis, ureter, bladder and urethra were obtained from porcine fetuses. Samples were examined by RT-PCR (AQPs 1-11), QPCR (AQPs positive on RT-PCR), and immunohistochemistry. Bladder samples were additionally examined by Western blotting. RNA was extracted from 76 tissue samples obtained from 19 fetuses. Gestational age was 60 (n=11) or 100 days (n=8)...

INTRODUCTION: There are numerous reports in the literature describing acute kidney injury in pregnancy (P-AKI) due to various obstetric complications. However, there is a dearth of studies on AKI related to pregnancy-specific disorders from India. We aimed to analyze clinical features and outcome of P-AKI related to pregnancy-specific disorders compared to total pregnancy, in India. METHOD: All pregnant women attending the department of Obstetrics and Gynecology from November 2014 to July 2016 were screened for AKI based on: (1) sudden elevation of serum creatinine ≥ 1 mg/dl; (2) oligoanuria for > 12 h; and (3) need for dialysis...

Frédéric Panthier, Fabien Lareyre, Marie Audouin, Juliette Raffort
Pelvi-ureteric junction obstruction corresponds to an impairment of urinary transport that can lead to renal dysfunction if not treated. Several mechanisms can cause the obstruction of the ureter including intrinsic factors or extrinsic factors such as the presence of crossing vessels. The treatment of the disease relies on surgical approaches, pyeloplasty being the standard reference. The technique consists in removing the pathologic ureteric segment and renal pelvis and transposing associated crossing vessels if present...

INTRODUCTION: Fetal hydronephrosis (HN) occurs in around 5% of pregnancies and its prognosis depends mainly on the grade of the dilation. We attempted to determine the fate of isolated, unilateral, high-grade HN in children with antenatal diagnosis, emphasizing the risk factors for progression. METHODS: We retrospectively evaluated 424 children (690 kidney units) with antenatal HN in the period between 2010 and 2014. We included only those patients with isolated showed SFU Grade 3 HN in 24 (54%) and SFU Grade 4 HN in 20 (46%)...
