RESUMEN
Objective To investigate the efficacy and feasibility of percutaneous puncture and catheterization sclerotherapy for the treatment of kidney cyst under ultrasonographic guidance. Methods Fifty-seven patients with simple renal cysts were divided into study group (30 cases) and control group (27 patients) according to the therapies. In study group, patients who had the cyst diameter ≤6.0 cm( 17 cases) received direct puncture sclerotherapy, while ＞6.0 cm (13 cases) received catheterization puncture sclerotherapy. In control group, patients who had performed laparoscopic surgery. Observed and compared the efficacy, hospitalization time, operative time and complications of two groups. Results Both groups had no case of recurrence after surgery. The effective rates in study group and control group were 93.3%(28/30 ) and 96.3% (26/27) respectively, and there was no statistical difference between two groups (P ＞ 0.05). The hospitalization time and operative time in study group [( 2.3 ± 1.7 ) d, ( 13.5 ± 3.7 ) min] were significantly shorter than those in control group [(5.8 ±2.2) d, (57.7 ±8.9) min] (P＜0.05); but the incidence of complications had no statistical difference between two groups (P ＞ 0.05). Conclusions Percutaneous puncture and catheterization sclerotherapy for the treatment of kidney cyst under ultrasonographic guidance has some advantages as good efficacy, less traumatic, rapid recovery and fewer complications. It is especially suitable to be used in the primary hospital.
