Bladder dysfunction remains a major postoperative challenge for early stage cervical cancer patients. The present prospective phase 2 trial in patients with stage IB1 and IIA1 cervical cancer follows up on our previous, unpublished work describing a new surgical landmark, the paravesico-vaginal space. We describe a novel nerve-sparing radical hysterectomy (NSRH) approach to treat early stage cervical cancer without compromising local control rate or survival. Between September 2015 and August 2016, 49 patients were enrolled to receive NSRH...

INTRODUCTION: The ureter is a retroperitoneal organ. Ureteral injuries are rare, with a prevalence of 0.083% of surgical interventions over 10 years. The objective of this study was to evaluate the surgical management of ureteric injuries according to the time of discovery, their size and their location. We also evaluated the results of this management on the renal repercussion as well as the predictive factors of the severity of the ureteric injuries. MATERIAL AND METHODS: This was a monocentric retrospective study carried out on the basis of a systematic review of the CHU surgery files...

Animal tissue has an extended history of clinical use in applications like heart valve bioprosthesis devices, cardiovascular surgical applications etc. but often does not last longer after implantation in the body due to rapid unwanted degradation. The goal of this work is to develop novel composite biomaterials by grafting biological tissue with synthetic, biodegradable polymers. In the current research phase, porcine submucosa, ureter and bovine pericardial tissue are grafted with poly DL-lactide (PLA), poly glycolide (PGA) and poly DL-lactide glycolide (PLGA) copolymers...

Telocytes (TC) are the delicate interstitial (stromal) cells defined by their long, thin and moniliform processes termed telopodes. Numerous studies determined that different subsets of telocytes populate almost all tissues and attempted to relate these subsets to various functions, from cell signaling to tissue repair and regeneration. Extremely few studies addressed the urinary tract though few data on the molecular pattern of the urinary TCs actually exist. We therefore hypothesized that subsets of urinary TCs co-localize within the human ureter and we aimed at performing an immunohistochemical study to evaluate the tissue-specific molecular pattern of TCs...

INTRODUCTION: Previous studies of the safety of renal autotransplantation (RAT) have been limited by a lack of evidence. Because of the influence of the opposite kidney, it is difficult to evaluate actual renal function. This study evaluated the actual results of RAT by collecting only cases involving a solitary kidney. METHODS: Between September 1, 1999, and November 30, 2015, 9 RAT procedures were performed in 9 patients with a solitary kidney. We retrospectively evaluated medical data collected prospectively...

To evaluate the safety and efficacy of retroperitoneal laparoscopic ureterolithotomy (RLU) in the treatment of proximal ureteral stones accompanied with obstructive pyelonephritis without preoperative drainage.We retrospectively reviewed 21 cases of proximal ureteral stones with infected kidney undergoing RLU between July 2013 and September 2016. Stone-induced obstructive infected hydronephrosis was diagnosed using blood and urine tests and imaging modalities. Empirical effective broad spectrum antibiotic therapy was initiated immediately, and then urgent RLU was performed without preoperative drainage...

BackgroundFibroblast growth factor receptor 2 (Fgfr2) deletion from murine peri-Wolffian duct stroma (ST) results in aberrant ureteric bud induction, abnormal ureteral insertion into the bladder, and high rates of vesicoureteral reflux (VUR). It is unclear which receptor docking protein(s) is/are responsible for Fgfr2 actions in these tissues. We investigated whether the docking protein, fibroblast receptor substrate 2α (Frs2α), had a role in peri-Wolffian duct ST similar to Fgfr2.MethodsWe conditionally deleted Frs2α in peri-Wolffian duct ST with a Tbx18cre mouse line (Frs2α(ST-/-))...

INTRODUCTION: Duplication of the upper urinary tract is one of the most common congenital urological anomalies. In patients with critically decreased or lost function of one of the renal segments, heminephrureterectomy is usually the treatment of choice. Until recently, this was an open surgery; in cases of complete removal of the ureter, an additional incision in the iliac region was required. Currently, heminephrureterectomy is increasingly performed laparoscopically. We report the experience in laparoscopic heminephrureterectomy (LHNUE) in 10 clinics in Russia and Belarus...

Ultrasonography (US) is frequently the first imaging modality used to examine women with symptoms involving the pelvis. It is widely available and involves no exposure to ionizing radiation. Images can be acquired with a transabdominal, endovaginal, or translabial approach, and the use of video clips and three-dimensional reconstructions can be helpful. US is excellent for assessment of the uterus, ovaries, and adnexa. Occasionally, nongynecologic pelvic diseases arising from the gastrointestinal, genitourinary, and musculoskeletal systems and the pelvic peritoneal and extraperitoneal spaces may be detected and can be a source of diagnostic dilemma...

Hyperpolarized (13) C magnetic resonance imaging (MRI) may be used to non-invasively image the transport and chemical conversion of (13) C-labeled compounds in vivo. In this study, we utilize hyperpolarized (13) C MRI to evaluate metabolic markers in the kidneys longitudinally in a mouse model of partial unilateral ureteral obstruction (pUUO). Partial obstruction was surgically induced in the left ureter of nine adult mice, leaving the right ureter as a control. (1) H and hyperpolarized [1-(13) C]pyruvate MRI of the kidneys was performed 2 days prior to surgery (baseline) and at 3, 7 and 14 days post-surgery...
