The imaging procedures available today are unable to accurately differentiate between idiopathic and malignant RF. A biopsy is mandatory to confirm the diagnosis, but there is no consensus regarding the template, timing and number of biopsies needed to exclude malignancy. Open ureterolysis represents the main surgical treatment for cases with severe IRF, and laparoscopic or robotic approach may be an option in selected cases. The recovery of the renal function is a surrogate for evaluating the success of the treatment. More clinical studies are needed in order standardize the protocol for diagnostic, treatment and follow up after medical or surgical management.
Increased hospitalization and operative time can be related to the large stone sizes and prolonged urine leakage. In our opinion, however, the overall success of laparoscopic ureterolithotomy makes it a feasible and effective procedure, especially for stones that could not be managed easily with ureteroscopic stone therapy.
BACKGROUND:We evaluated the importance and efficacy of 'stepped procedure' in laparoscopic cyst decortication as an initial experience in it.MATERIALS AND METHODS:A 36 renal cyst cases were included. The stepped retroperitonoscopic cyst excision divided into three groups. First step, doing the incisions to place the ports and expanding the retroperitoneal space with balloon distension, second step, placement of trocars and reach to the cyst, third step, aspiration and decortication of the cyst. The difficulty of the sessions was measured with the Visual Analog Scale (VAS) scoring system. Score was determined according to the difficulty of the surgical step ranging from '0' to '10', '0', too easy, '10' too difficult'. The durations were measured. One-way ANOVA test was used for statistical analysis.RESULTS:The mean age was 52.0 (20-75) years. The mean operation time was 52.0 min. The mean duration of the first step was 12.5, second, 26.0 and third, 22.5 min. The mean VAS of first step, 3.2, second, 6.0 and third, 3.6 There were only significant differences in duration time and VAS score for second step among the surgeons (P<0.05).CONCLUSIONS:Laparoscopic cyst decortication may provide gaining experience to approach the kidney laparoscopically. The side, size and localization of cysts were not found associated with the difficulty of the method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
