Laparoscopic treatment of retroperitoneal fibrosis.

[Laparoscopic treatment of retroperitoneal fibrosis.] Arch Esp Urol. 2017 May;70(4):468-474 Authors: Hernández Fernández C, Subirá Rios D, Moralejo Gárate M, Rodríguez Fernández E, Caño Velasco J, Herranz Amo F Abstract OBJECTIVES: Retroperitoneal fibrosis is a disease that may condition a severe involvement of various organs, mainly upper urinary tract, even causing renal insufficiency. It was first described by Albarran in 1905 and it is also known as Ormonds disease. The correct diagnosis includes, in many cases, the performance of one or more tests: CT scan, MRI, renal scan, etc. It is often necessary the insertion of double J catheters on percutaneous nephrostomy tubes with the aim to preserve renal function. Initial treatment is medical, based on corticoids, and , less frequent, immunosuppressive or chemotherapy drugs. Surgery is the treatment of choice when ureteral entrapment by the fibrous plaque is not solved with medical treatment. Such operation may be performed with a conventional open approach (laparotomy) or by pure, hand assisted laparoscopic surgery, or robotic surgery. In all cases, the technique involves freeing the ureters from the fibrous plaque that entraps them, leaving them intraperitoneal, and it is recommendable to wrap them with an omental flap. The implantation of minimally invasive techniques has made that, in groups with experience in laparoscopy, open surgery is being abandone...

An 80-year-old woman presented with gross hematuria and flank pain. She also complained of asthenia and severe weight loss lasting for 1 month. The patient had been treated 10 years prior for a bladder carcinoma by radical cystectomy and continent skin diversion. She then experienced multiple urinary tract infections and had a chronic left ureteral stenosis that required repetitive ureteral stent. Her past medical history was also remarkable for diabetes mellitus. Her physical examination was normal, blood pressure was 170/70 mm  Hg, and temperature was 35.9°C.

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

Acquiring surgical skills requires regular practice. Medical evidence supports that these skills can be learned outside the operating room (OR). The aim of the current study was to describe the first laparoscopic simulator for ureteral reimplantation (LAP-SPUR) following Lich- Gregoir technique.

Authors: Sridharan K, Sivaramakrishnan G Abstract INTRODUCTION: Alpha blockers (AB) are the main group of drugs used for medical expulsive therapy (MET) in patients with ureteral stones. However, there is no consensus on the relative efficacy and safety of individual AB in MET. Areas covered: The present work is a network meta-analysis of randomized controlled trials comparing AB with either placebo or standard of care in patients with ureteral stones. Electronic databases of Medline, Cochrane CENTRAL and Google Scholar were searched for eligible clinical studies. Inverse variance heterogeneity model was used for m...

AbstractBackgroundUreteral stents are commonly placed before colorectal resection to assist in identification of ureters and prevent injury. Acute kidney injury (AKI) is a common cause of morbidity and increased cost following colorectal surgery. Although previously associated with reflex anuria, prophylactic stents have not been found to increase AKI. We sought to determine the impact of ureteral stents on the incidence of AKI following colorectal surgery.MethodsAll patients undergoing colon or rectal resection at a single institution between 2005 and 2015 were reviewed using American College of Surgeons National Surgical...

Conclusion: With early source control, obstructive UTI outcomes were comparable to nonobstructive UTI. However, despite undergoing ureteric stenting, more patients with obstructive UTI required RRT than those with nonobstructive UTI.

With the increasing use of the robotic platform, some surgeries which were historically performed open have transitioned to a minimally invasive technique. Recently, the robotic approach has become more utilized for ureteral reconstruction. In this article, the authors review the surgical techniques for a number of major ureteral reconstuctive surgeries and bri...

Conclusion: High prevalence of bacterial isolates and risk of bacteriuria and colonization was found in the DJ stent tips, with E. coli being dominant colonizer. Most of the bacteria were resistant to different classes of antibiotics. Bacteriuria and stent colonization gradually increases with the duration of stent retention in the body.
