ABSTRACT
We evaluated the results of mini–percutaneous nephrolithotomy (mini-PCNL) under ultrasonic guidance for treatment of kidney stones at Thanh Hoa General Hospital. This descriptive study examined, from July 2016 to September 2018, 300 cases of kidney stones performed mini-PCNL under ultrasonic guidance. Nephrolithotripsy was done by 30 and 100w Homium lasers. The 300 patients included 63.3% men and 36.7% women. The mean age was 42.13 ± 33.4 years. Recurrent stones were found in 15%, renal pelvis and one calyx stone in 51.7%. Hydronephrosis before surgery at level 1 was found in 46.7%. Stone average length was 3.11 ± 0.63cm and average area was 5.16 ± 2.41cm2. Tunnel position in the middle calyx was found in 68.3%. Average surgery time averaged 58.42 ± 27.8 minutes. Bleeding during surgery was reported for 15 patients, hematuria after surgery in two patients, and fever after surgery in 46 patients. The average hospitalization duration was 4.6 ± 2.3 days. Early stones clearance rate was 78.3%. Mini–PCNL under ultrasound guidance with a 30 – 100w Holmium Laser energy source is a useful method of treating kidney stones safely, achieving an early stone clearance efficiency of 82.4%,and a low rate of postoperative complications of 16.7%. This method can effectively replace open surgery for the treatment of kidney stones.
