PURPOSE OF REVIEW: Although open ureteral reimplantation remains the gold standard for surgical correction of vesicoureteral reflux (VUR), robotic-assisted laparoscopic ureteral reimplantation (RALUR) holds promise and is becoming more widely utilized. The present article outlines primary operative techniques for RALUR, summarizes the current literature with respect to surgical outcomes and costs, and discusses early applications of RALUR to complex and reoperative cases. RECENT FINDINGS: Intravesical and extravesical techniques for RALUR have been described...

Renal fibrosis is a significant threat to public health globally. Diverse primary aetiologies eventually result in chronic kidney disease (CKD) and immune cells influence this process. The roles of monocytes/macrophages, T cells and mast cells have been carefully examined, whilst only a few studies have focused on the effect of B cells. We investigated B cell function in tubulointerstitial fibrosis induced by unilateral ureteral obstruction (UUO), using genetic B cell-deficient μMT mice or CD20 antibody-mediated B cell depleted mice...

To establish if a retropulsion prevention device for ureteral stones equalizes surgical success and push-back rates of Ho:YAG laser and pneumatic lithotripters for upper ureteral stones. Patients with upper ureteral stones (n = 267) were treated endoscopically at the Department of Urology between April 2014 and December 2015. Patients were randomly assigned to pneumatic and Ho:YAG laser lithotripters as group-1 and group-2, respectively. Lithotripsy was performed with Stone Cone(TM) in both groups. The surgical success rate on the first postoperative day was 81...

A 24-year-old woman with a high fever presented at our hospital. She had been diagnosed with Kabuki syndrome at the age of 4 years because she had the typical facial features of the condition ; she had undergone living donor renal transplantation 12 years prior. She was prescribed a course of antibiotics to treat pyelonephritis of the transplanted kidney and the high fever disappeared, but the fever developed again 3 days after the discharge. Abdominal computed tomography revealed a tubular structure of recent onset running from the left dorsal side to the lower part of the bladder...

STAT3 is a transcription factor implicated in renal fibrotic injury, but the role of STAT3 in mesenchymal stem cell (MSC)-induced renoprotection during renal fibrosis remains unknown. We hypothesized that MSCs protect against obstruction-induced renal fibrosis by downregulating STAT3 activation and STAT3-induced matrix metalloproteinase 9 (MMP-9) expression. Male Sprague-Dawley rats underwent renal arterial injection of vehicle or MSCs (1 x 106 per rat) immediately prior to sham operation or induction of unilateral ureteral obstruction (UUO)...

Open ureterolithotomy and pyelolithotomy used to be first line therapy for treating kidney and ureteral stones. With the advent of shockwave lithotripsy, open stone surgery became less prevalent, but once ureteroscopy became more prevalent, open stone surgery became all but extinct. Advances in smaller, more flexible endoscopes and improvements in intracorporeal lithotripters, ureteroscopy has become a mainstay of therapy for kidney stones. The holmium:YAG laser can be utilized through flexible instruments and fragments any stone no matter what it is composed of...

This study was designed to evaluate the role of urinary and serum carbohydrate antigen 19-9 (CA19-9) as a biomarker in the assessment of patients with ureteral stone. A total of 38 patients with ureteral stone and hydronephrosis who underwent transurethral lithotripsy (TUL) (Group A) and 24 age-matched healthy controls (Group B) were evaluated in this study. Urinary and serum CA19-9 concentrations were measured in group A patients before TUL as well as 4 and 8 weeks following the operation. Urinary and serum CA19-9 concentrations were also measured in group B participants...

After presenting with nonspecific symptoms, a 52-year-old female was found to have a 3.4 × 2.6 cm retroperitoneal mass resulting in hydronephrosis on abdominal computed tomography scan. After extensive workup including surgical debulking, excisional biopsy, and autoimmune panel, she was found to have idiopathic retroperitoneal fibrosis (IRF) with negative staining for immunoglogulin G4 (IgG4). Two years after presentation, the patient developed dyspnea, cough, and xerostomia. Repeat anti-Sjögren Syndrome A and anti-Sjögren Syndrome B titers and labial gland biopsy confirmed the diagnosis of concomitant Sjögren's syndrome (SS)...

Inverted-Y ureteral duplication is one of the rarest anomalies of ureteral branching. We encountered a 20-year-old female patient with persistent incontinence even after nephrectomy for ectopic ureteral insertion into the vagina. She had inverted-Y ureteral duplication between the bladder and vagina, and urine was being transported from the bladder to the vagina. To the best of our knowledge, this is a rare case of inverted-Y ureteral duplication with ectopic ureteral insertion into the vagina as well as the ureter into the bladder, which became apparent due to persistent urinary incontinence even after nephrectomy...

AIMS: Sorafenib, which has been used extensively for the treatment of renal cell cancer and advanced hepatocellular carcinoma (HCC), has also been shown to have antifibrotic effects in liver fibrosis. However, the effects of sorafenib on renal fibrosis are unknown. Therefore, we investigated whether sorafenib inhibited renal fibrosis in a mouse model of unilateral ureteral obstruction (UUO) and further explored the potential mechanism. METHODS: Mice underwent UUO followed by vehicle or sorafenib treatment...

Acute graft pyelonephritis is a very common infection in renal transplantation. The impact of acute graft pyelonephritis (AGPN) on graft and patient outcome has not yet been established. Eight hundred seventy kidney and kidney-pancreas transplants were retrospectively studied, over last 13 years, to verify occurrence of AGPN in the first 30 days post-transplantation. We found that 112 patients (15.8%) presented post-transplantatiom AGPN up to 30 days after a kidney transplantation. The occurrence was higher in older patients (P = ...
