A six-month-old child was admitted into our center with complaint of hydronephrosis in June 2018. He was diagnosed as embryoid rhabdomyosarcoma after cystoscopy with biopsy. After 22Gy radiotherapy and 4 cycles chemotherapy(VAC), robot-assisted radical cystectomy was performed. The orthotopic neobladder was reconstructed with sigmoid colon and bilateral ureter were reimplanted in Politano-Leadbetter technique. The patient was discharged after 14 days and chemotherapy was continued. Recent ultrasound examination showed that his maximal bladder capacity had increased to 120 ml, and intravenous urography revealed no urine leakage.

Conclusions: In our experience, the incidence of post-URS ureteral stricture is low. The impacted stone is the most common cause of URS complications and hence stricture formation.

Conclusions: Laparoscopic pyeloplasty and concomitant flexible renoscopy through lowermost trocar with basket extraction is a simple, attractive alternative for the simultaneous treatment of ureteropelvic junction obstruction presenting with coexisting nephrolithiasis. This method is useful and feasible, with minimal invasiveness and an early post-operative recovery.

This study retrospectively summarized the clinical diagnosis and treatment of fibroepithelial polyps>5 cm in length in the proximal ureter of 6 patients who received treatment in the Affiliated Renji Hospital of Shanghai Jiaotong University School of Medicine between December 2010 and February 2017. The length of fibroepithelial polyps ranged from 5.8 to 8.2 cm. There were 4 males and 2 females with the mean age of 32.6 ± 9.8 years. Unilateral polyps were found in all patients (right: n = 4; left: n = 2). Hydronephrosis of different extents was noted in these patients, 4 complained of back pain an...

Question: A 19-year-old man presented to the emergency department (ED) with upper abdominal and right flank pain. Vital signs were: temperature, 36.3 °C; blood pressure, 121/66 mm Hg; heart rate, 77 beats/min; and respiratory rate, 18 breaths/min. Physical examination revealed right flank percussion tenderness at the costovertebral angle. No bruising was present. Two weeks prior to arrival at ED, an intravenous urography (IVU) revealed a radiopa que calcified spot (3×7 mm) in right upper ureter with hydronephrosis.

CONCLUSIONS: A CT angiography with 3D reconstruction provides a more accurate diagnostic approach for the congenital hydronephrosis caused by aberrant renal vessel. Thus, it can offer surgeons very important information in the pre-surgery planning. PMID: 29480234 [PubMed - in process]

The objective is to compare the results of robotic-assisted pyeloplasty using transperitoneal and retroperitoneal approaches in a prospective randomised single surgeon study. 80 consecutive patients with primary ureteropelvic junction obstruction were prospectively randomised between transperitoneal (40 patients, group 1) and retroperitoneal (40 patients, group 2) robotic-assisted pyeloplasty. All patients underwent preoperative clinical evaluation, retrograde urography, and diuretic isotope renography. All operations were performed by a single-experienced surgeon. Patients were followed up by postoperative clinical examin...

Conclusions: Preoperative differential renal function cannot independently predict the recoverability of postoperative renal function in adult patients with unilateral renal obstruction-induced hydronephrosis. SFU grade, renal pelvic type, PHAR, preoperative RRI, and decline in RRI were significantly associated with the recoverability of renal function in adult patients aged #x3c;35 years, while only SFU grade, renal pelvic type, and PHAR were significantly associated with renal function recoverability in patients aged ≥35 years. Renal function recovery was better in patients younger than 35 years when compared with older patients.Urol Int

ConclusionsNotwithstanding the limitations of the present study, the in vivo testing of our novel natural origin polymer-based BUS suggests this device to feature homogeneous degradation, good urine drainage, and high biocompatibility. Next steps will be to increase its stability, and to improve the radiopacity without compromising its degradation. Ultimately, clinical studies will be required to determine the safety and feasibility of its use in humans.
