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...

In this issue ofJAMA Internal Medicine, Meltzer and colleagues report the results of a randomized clinical trial assessing the role of an α-blocker, tamsulosin, among patients presenting to the emergency department with renal colic secondary to a ureteral stone. In the absence of indications for immediate intervention (eg, pyelonephritis, obstruction of a solitary kidney, intractable pain), a trial of conservative treatment is warran ted in this population, given that many patients will pass their stones spontaneously. However, since a number will fail conservative treatment and require a procedure for stone removal,...

In this randomized clinical trial, participants were randomized to treatment with either tamsulosin, 0.4 mg, or matching placebo daily for 28 days to determine if tamsulosin promotes the passage of urinary stones within 28 days among emergency department patients.

CONCLUSION: The decrease in lasing time achieved by the Moses system does not translate into sufficient cost savings to off-set the higher cost of the laser fiber and software. PMID: 29900818 [PubMed - in process]

Interventional endoscopy and interventional radiology have led to the development of minimally invasive techniques for management of kidney and ureteral diseases in the dog and cat including idiopathic renal hematuria, ureteral obstruction, and ectopic ureters. Sclerotherapy is a renal-sparing chemical cauterization technique used in cases of idiopathic renal hematuria. Diagnosis of ureteral obstruction is challenging in some cases based on ultrasound alone and antegrade pyelography should be considered. Treatment options for obstructions include nephrostomy tubes, ureteral stents, and subcutaneous ureteral bypass devices....

CONCLUSION Ureteric injury has significant morbidity and is the commonest reason for litigation following hysterectomy with an estimated risk of 0.02 - 0.4%. [1,2] Ureterolysis is infrequently practiced by benign gynaecologists however, is necessary during complex surgery. Benign pathology requiring hysterectomy such as endometriosis, fibroids, large uteri and adnexal masses are recognised risk factors for ureteric injury. [3] Most injuries occur during division of the uterine artery at the level of the internal cervical os. The average distance between the ureter and cervix is 2 cm but it is 0.5 cm in 3.2% of the populati...
