ABSTRACT

Background: The aim of parapelvic cyst treatment is to have complete drainage of cyst fluid and prevent its further compression of the kidney and collective system. This study explores the efficacy and safety of surgical approaches with holmium laser ureteroscopic internal drainage in the treatment of parapelvic cyst.

Methods: The compression effect of parapelvic cyst on the renal collective system was observed by rigid ureteroscope using retrograde ureteroscopic technology. With direct vision, the cyst wall on the obvious parapelvic compression site was cut. The diameter of the cyst wall cut was about 1 cm. The internal drainage was obtained by double-J tubes. When the cyst was in the inferior pole of kidney or where the rigid ureteroscope could not reach, a flexible ureteroscope was used.

Results: In 28 cases of operation, 27 cases were successful. The cyst treatment time was eight to 40 minutes (average 26 minutes). During the operation, no massive haemorrhage, damage of nearby organ and ureter, or other complications happened. Time of follow-up was 10–72 months (average 39 months). The results of follow-up showed that in 22 cases, the cyst disappeared; the diameter of the cyst in four cases was reduced by more than half, and one case recurred.

Conclusion: The treatment of parapelvic cyst by internal drainage operation using holmium laser and ureteroscopy was effective. The operation was safe with few complications.
