[Ultrasound guided percutaneous puncture and sclerotherapy with alcohol for peripelvic cysts].
OBJECTIVE
To summarize the experience of ultrasound guided percutaneous aspiration and sclerotherapy for peripelvic cysts and investigate the clinical effect.


METHODS
A total of 169 cases of peripelvic cyst patients were evaluated, of whom 36 cases (21.3%) had hydronephrosis secondary to peripelvic cysts, 8 cases (4.7%) had renal calculus. All patients underwent ultrasound and intravenous phelography (IVP) examination, 59 patients also had CT scan. Hydatid fluid was analyzed by amine test. Percutaneous aspiration was guided by ultrasound, 95% alcohol was used to sclerosis the peripelvic cysts when amine test was negative or positive but did not have communication with pelvis through opacification. Ultrasound were done at 1, 3, 6 months and every 1 year thereafter, follow-up period were 6 months to 5 years.


RESULTS
One hundred and sixty-five peripelvic cysts (97.6%) were cured by once sclerotherapy, the diameter of another 4 cases (2.4%) diminished to less than 1.5 cm by once sclerotherapy. Thirty-six cases of hydronephrosis were all resolved after sclerotherapy. Eight cases had renal calculus, of whom 4 cases underwent extracorporeal shockwave lithotripsy, 2 cases underwent percutaneous nephrolithotomy, and 2 cases did not treat the stone. Five patients had gross hematuria after aspiration, but all diminished in 3-5 d.


CONCLUSIONS
Ultrasound guided percutaneous aspiration and sclerotherapy for peripelvic cysts had the superiority of safety, effectiveness micro-invasion and low complication.
