Ureteroscopic management of asymptomatic and symptomatic simple parapelvic XXXX .

@entity1 @entity8 @entity812
BACKGROUND: To investigate feasibility and safety of treating simple parapelvic @entity8 using flexible ureteroscopy with the Holmium laser. METHODS: Between February 2010 and July 2013, a total of 21 @entity1 , aging from 29 to 71 (49.00        13.23), were diagnosed with parapelvic @entity8 by ultrasonography in combination with contrast-enhanced computer tomography (CT) and intravenous urography (IVU) in the Department of Urology Surgery, @entity1 's Hospital of the Zhejiang province. Fifteen @entity1 were asymptomatic and 6 @entity1 were symptomatic with @entity812 . All @entity1 underwent drainage of the cysts using flexible ureteroscopy with Holmium laser. @entity1 were followed up 1, 3 and 12  months after the operation. RESULTS: The intervention was successful in 20 @entity1 and failed in 1 @entity1 who, subsequently successfully underwent a laparoscopic cyst removal. There were no intra-operative and post-operative complications reported. The mean operation time was 27  min (range: 15 to 45  min). The mean hospital stay was 2.6  days (range: 1 to 5  days). Twenty @entity1 were followed up until 15  months after surgery. After such ureteroscopic management, there were no @entity8 detected in 7 @entity1 (35  %) and a reduction in size of the @entity8 was found in 13 @entity1 (65  %). @entity812 subsided in all 6 (100  %) previously symptomatic @entity1 . CONCLUSIONS: Flexible ureteroscopy with the Holmium laser may be a feasible and effective treatment option in selected @entity1 with simple parapelvic @entity8 . Further prospective randomized studies that compare the procedure to laparoscopic treatments are needed.
