Ureteroneocystostomy Herniation Leading to Obstructive Uropathy 10 Years Postrenal Transplant: a Rare Case Report [Downloaded free from http://www.urologyannals.com on Monday, January 25, 2021, IP: 158.232.3.16] Case Report Ureteroneocystostomy herniation leading to obstructive uropathy 10 years postrenal transplant: A rare case report Shailesh Chandra Sahay, Dilip Bhalla1, Pawan Kesarwani, Madan Sethi1 Departments of Urology and 1Nephrology, Max Superspeciality Hospital, Patparganj, Delhi, India Abstract Herniation of the urinary bladder is observed in around 1%–4% of cases. Bladder herniation rarely presents with obstructive uropathy; however, bladder herniation carrying ureteroneocystostomy and leading to obstructive uropathy of the graft is even rare. Here, we present a case of a 36-year-old male with deranged renal function test who had undergone renal transplant 10 years back. Computed tomography scan revealed bladder herniation with ureteroneocystostomy and hydronephrosis. He was surgically explored by Gibson incision and ureterolysis, and hernioplasty was performed. Although the cause of herniation was ureteroneocystostomy, it was managed immediately without any need for percutaneous nephrostomy.

    Information about your procedure from The British Association of Urological Surgeons (BAUS) This leaflet contains evidence-based information about your proposed urological procedure. We have consulted specialist surgeons during its preparation, so that it represents best practice in UK urology. You should use it in addition to any advice already given to you. To view the online version of this leaflet, type the text below into your web browser: http://www.baus.org.uk/_userfiles/pages/files/Patients/Leaflets/Ureterolysis.pdf Key Points • Retroperitoneal fibrosis (RPF), also known as chronic periaortitis, forms at the back of your abdominal (tummy) cavity and can block your ureters (the tubes that carry urine from your kidneys to your bladder) • Ureterolysis is used to free your ureters from the blockage caused by the RPF • In most patients, the procedure involves open surgery through a long incision in your abdomen (tummy) but it can sometimes be done by laparoscopic (keyhole) surgery • To prevent further obstruction, we wrap your ureters in omentum (the fatty envelope inside your abdomen) or in a synthetic material • The procedure is usually reserved for patients in whom medical treatment has been unsuccessful • Care of patients with RPF is multi-disciplinary with physicians, expert surgeons and other specialists collaborating in your care What does this procedure involve? Freeing your ureters from scar tissue at the back of your abdomen to relieve the blockage and restore urine drainage from your kidneys. To prevent recurrence, we wrap your ureters in omentum (a sheet of fatty tissue found in your abdomen); if your omentum has been removed or is too small to use, we may wrap the ureters in a synthetic material.

  • Laparoscopic Ureterolysis Without Omentoplasty in the Management of the Uropathy Secondary to Idiopathic Retroperitoneal Fibrosi
    CASE REPORT Laparoscopic Ureterolysis without Omentoplasty in the Management of the Uropathy Secondary to Idiopathic Retroperitoneal Fibrosis Miguel A Bergero1, Patricio A Garcia Marchiñena2, Guillermo Gueglio3, Carlos David4, Fernando Dipatto5, Alberto Jurado6 ABSTRACT Introduction: Obstructive uropathy (OU) secondary to idiopathic retroperitoneal fibrosis (IRF) is an infrequent disease, and the standard treatment has not been established. However, ureterolysis with ureteral intraperitonealization is an effective therapeutic alternative. We present the successful management of OU secondary to an IRF by laparoscopic ureterolysis without omentoplasty (LUWO). Materials and methods: A retrospective descriptive study of 5 patients with IRF treated with LUWO was performed. Results: The average age was 60.4 years. The average creatinine was 3.86 mg/dL. There were no intraoperative or major postoperative complications. In a follow-up period of 31.2 months, all patients are asymptomatic, with an average creatinine level of 1.52 without dialysis requirement. No patients required corticosteroid therapy after surgery. Conclusion: Laparoscopic ureterolysis without omentoplasty is a safe and feasible option to treat the OU caused by IRF that provides good results in the medium-term follow-up, as we describe it in our series of cases.

  • Management of Ureteric Endometriosis Associated with Hydronephrosis: an Australian Case Series of 13 Patients Ian AR Smith1,2,3*, Michael Cooper4
    Smith and Cooper BMC Research Notes 2010, 3:45 http://www.biomedcentral.com/1756-0500/3/45 SHORT REPORT Open Access Management of ureteric endometriosis associated with hydronephrosis: An Australian case series of 13 patients Ian AR Smith1,2,3*, Michael Cooper4 Abstract Background: Hydronephrosis is a rare but serious manifestation of ureteric endometriosis. Findings: One hundred and twenty-six women underwent ureterolysis for ureteric endometriosis betweeen and October 1996 and June 2009. Thirteen of the 126 women were identified as having ureteric obstruction at the time of their procedure and were included in the case series. The median age was 39.5 (30 - 63). Chronic pelvic pain was the most common presenting symptom (53.8%). The point of ureteric obstruction was noted to occur most commonly at a small segment of distal left ureter, where it is crossed by the uterine artery (54%). Seven of the 13 women (53.8%) were successfully managed with ureterolysis only. Three of the 13 women (21.3%) underwent ureterolysis and placement of a double J ureteric stent. Three of the 13 (21.3%) required a segmental ureteric resection. There was one incidence of inadvertent thermal ureteric injury which was managed with a ureteric stent. In all cases the hydronephrosis had resolved at six months follow up. Conclusions: Our findings support the growing body of literature supporting ureterolysis as the optimal treatment for ureteric endometriosis causing moderate to severe ureteric obstruction. Introduction present within the muscularis propria, lamina propria or Endometriosis is a benign disease defined by the pre- ureteral lumen [6] In extrinsic cases endometriosis sence of ectopic endometrial glands and stroma, often occurs within the ureteral adventitia and adjacent soft associated with pelvic pain and infertility.
