Abstract

Abstract:

Objective

To explore the efficacy and safety of flexible ureteroscopic intrapelvic drainage with holmium laser in the treatment of parapelvic cyst.

Methods

The clinical data of 16 patients treated with flexible ureteroscopic incision and drainage using holmium laser between January 2015 and January 2017 were summarized in Henan Provincial Hospital. Ten male and six female patients were enrolled eventually, ranging from 40 to 71 years old, with an average of 54 years old. Pretheroputic evaluation included uranalysis, ultrasonography, intravenous or CT urography (IVU or CTU) and CT angiography (CTA). All of the parapelvic cysts were unilateral and the diameters were 3-7 cm. Bosniak I cysts were indentified in all 16 cases.Two cases were accompanied with simple renal cysts (SRC) ipsilaterally or contralaterally,and one case with renal calculus.

Results

The operations were successful in all 16 patients without conversions to open surgery. The average operative time was 40 min (range 29-56 min). The average postoperative hospital stay was 6 days (range 5-7 days). After a follow-up of 3-24 months, the cysts disappeared in 13 patients and size reduced more than one half in 2 patients. One patient was detected with recurrent parapelvic cyst 1 year postoperatively and was cured by repeated procedure.

Conclusions

Flexible ureteroscopic intrapelvic drainage with holmium laser is minimally invasive, safe and effective, is an optimal option in the treatment of parapelvic cyst.
