OBJECTIVES: The standard treatment for FIGO stage 1B1 cervical cancer is radical hysterectomy (RH) [1]. Indocyanine-green (ICG) is a drug injected within the cervical stroma to detect the sentinel lymph node (SLN) in cervical cancer [2,3]. ICG travels through the lymphatic channels in the lateral parametrium, which results enhanced with green, before reaching the SLNs. This could help identifying the surgical landmarks. The aim of this video is to propose a new approach to perform parametrial dissection as part of RH under the guidance of ICG...

Ureter reconstruction is a difficult procedure in urology. Adipose-derived stem cells (ADSCs), along with multipotency and self-renewal capacity, are a preferred choice for tissue engineering-based ureteral reconstruction. We explored the synergic role of cathelicidin LL37 (LL37) in epithelial and smooth-muscle-like differentiation. ADSCs were separated from adipose tissues of mouse and characterized by flow cytometry. The ADSCs were then stably transfected with pGC-FU-GFP (pGC) or pGC containing full-length LL37 (pGC-LL37), respectively...

INTRODUCTION: To evaluate the accuracy of transvaginal sonography for preoperative detection of bladder endometriosis and surgical outcomes regarding fertility and pain symptoms of women with urinary tract endometriosis. MATERIAL AND METHODS: Retrospective cohort study of consecutive patients with urinary tract endometriosis undergoing laparoscopic partial cystectomy and/or ureterolysis/decompression, ureteric resection and end-to-end anastomosis or ureteroneocystostomy for ureteral stenosis and hydronephrosis...

A unilateral megaureter was found in an elderly female cadaver during routine dissection. The left proximal ureter, which was thick and convolute, descended and entered into the pelvic cavity, where the distal ureter was attached to the posterior pelvic wall at the inlet level. Removal of connective tissue surrounding the attached region revealed ureteric entrapment in the sacroiliac joint. The ipsilateral kidney, from which the megaureter originated, showed no pelvicalyceal dilatation. In contrast, the left kidney was enlarged, weighing 24% more than the right kidney...

Retrocaval ureter is a rare developmental anomaly with an incidence of 1 in 1500 births. The inferior vena cava compresses the ureter posteriorly, causing upstream dilatation of the proximal ureter and the kidney. We report a 16-year-old girl who presented with right flank pain, diagnosed as retrocaval ureter with ultrasound, intravenous urogram and CECT, and was treated with laparoscopic transperitoneal ureteroureterostomy. Embryological aspects and laparoscopic technical considerations are highlighted in this case report...

AIM: The purpose of this study was to determine the incidence of ureteric obstruction (UB) and requirement for Cohen antireflux surgery (CAS) after DefluxⓇ treatment (DT) for vesicoureteric reflux (VUR). METHODS: Between 2011 and 2017, 494 ureters (VUR severity ≤ grade III: N=291 or >grade IV: N=203) were treated by DT at a mean age of 4.5 (range: 0.2-24) years. Epidural Catheter Assistance (ECA) was used to exclude UB by injecting diluted indigo carmine solution (1-3mL) into an epidural catheter inserted into a ureter after DT and confirming dye flow within 15min...

INTRODUCTION AND OBJECTIVES: We hypothesized that crowdsourcing assessments could be applied to the Post-Ureteroscopic Lesion Scale (PULS) for ureteral injury. METHODS: At a single institution, we prospectively digitally recorded 14 ureters at the terminal portion of standard ureteroscopic procedures. Each recording was reviewed by 10 global experts to determine a mean PULS score. Following training, the Crowd-Sourced Assessment of Technical Skills, C-SATS® (CSATS, Inc...

OBJECTIVE: To present our technique of ureteroileal bypass to treat uretero-enteric strictures in urinary diversion. MATERIALS AND METHODS: One hundred and forty-one medical records were reviewed from patients submitted to radical cystectomy to treat muscle-invasive bladder cancer between 2013 and 2015. Twelve (8.5%) patients developed uretero-enteric anastomotic stricture during follow-up. Five patients were treated with endoscopic dilatation and double J placement...

Stress urinary incontinence (SUI) is a common problem in women. Successful treatment is now mid urethral sling but it would be a cause of urethral obstruction. In this case report, a 50 years old woman presented with a huge introitus mass after 3 months of midurethral sling. The mass protruded from the urethra and could not be reduced. Emergency MRI of pelvis was demonstrated prolapsed ureterocele, single system of right ureter. Preoperative planning was cystoscopy and mass excision. The patient was preoperatively counseled that right ureteric reimplantation may be required...

Complete renal fusion without crossed renal ectopia denotes the medial fusion of the renal parenchyma (with or without changes in the microarchitecture) in the pelvis with anteriorly placed short ureters terminating into the bladder. This could be due to the failure of renal analgen to ascent, lateral migration, axial rotation, and persistence of primitive vascular supply. Though remain asymptomatic such cases warrant concomitant congenital anomalies of other organ systems as well as the microarchitecture changes in the renal parenchyma...

Objective: Vesicouterine fistula (VUF) is an uncommon cause of female genito-urinary fistula. Most of these fistulas are due to lower segment uterine cesarean section (LSCS). Traditionally, open surgical repair has been the traditional treatment. However, laparoscopic repair of VUF is a minimally invasive technique and few case reports have been published with short term follow up. In the present study, we are presenting our long- term outcome of laparoscopic repair of VUF. Material and methods: A retrospective analysis of 8 patients with VUF was performed from 2010 to 2015...

Objective: This study compared the stone opacity effect in patients who had radiopaque and radiolucent stones in percutaneous nephrolithotomy (PCNL) results. Material and methods: The medical records of 171 complete supine PCNL procedures were gathered. Patients were categorized into two groups: those with radiopaque (n=141) and those with radiolucent (n=30) stones. Kidney, ureter and bladder x-ray was done a day after PCNL and Ultrasound imaging was done two weeks later to evaluate the stone free rate...

OBJECTIVES: To report the treatment outcomes of patients with extrinsic ureteral obstruction treated with metallic stents and to identify the factors predicting stent failure. METHODS: A total of 52 patients with extrinsic ureteral obstruction as a result of malignancy (66 ureters) were treated with metallic stents (Resonance® ) and included in the study. The median observation period was 118 days. RESULTS: The median survival time of these patients was 210 days, and the stent patency rate was 86...

José Manuel Reis Santos
Stone surgery is one of oldest surgical practices undertaken by man. Hippocrates refused to let his followers "cut for the stone" and it was only in February 1980, when the first human trial of shock wave therapy on a renal stone was performed with success that a new era in minimally invasive treatment (surgery) for stones was opened up and this condemnation was finally resolved in the Hippocratic Oath. Endoscopy, using natural orifices, supported by anaesthesia, incremented by technology and with access to all points along the urinary tract, began by competing with ESWL, but is now the treatment of choice in most cases...

In a new paradigm of etiology related to Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD) kidney injury may cause induction of factors in the injured kidney that are released into the circulation and thereby initiate and maintain renal fibrosis and CKD-MBD. Klotho is believed to ameliorate renal fibrosis and CKD-MBD, while ActivinA might have detrimental effects. The unilateral ureter obstruction (UUO) model is used here to examine this concept by investigating early changes related to renal fibrosis in obstructed kidney, untouched contralateral kidney and vasculature, which might be affected by secreted factors from the obstructed kidney, and compared to unilateral nephrectomized controls (UNX)...

In aggressive cases, endometriosis can perturb the urogenital tract, in particular the ureter, which can potentially result in ureteral compression or stenosis. Even though this is rare, consequences are dramatic, such as hydronephrosis or organ failure. The present standard intervention comprises the resection of affected tissues and endometriosis foci combined with adjuvant hormonal therapy. When the ureter does not recover, ureteral reimplantation is required. The present case describes the successful laparoscopic approach of the reimplantation of the ureter with simultaneous cystoscopy...
