Abstract
ObjectivesTo evaluate the efficacy, safety and feasibility of tubeless microchannel percutaneous nephrolithotomy(MPCNL).
Methods68 patients with upper urinary calculi were treated with tubeless MPCNL. Among them, there were 41 cases of renal calculi, 27 eases of upper ureteric calculi. The max diameter of calculi was no more than 3 cm. All patients were retained conventional double-J tube and catheter indwelling without nephrostomy fistula after operation.
ResultsBlood loss of patients was 30~80 mL(average 55 mL), the operation time was 35~75 min[average (52.5±3.3) min]. The stone-free rate was 95.6%(65/68), and 3 patients with calculi residual[calculi residual by B ultrasound after 2 days, the diameter of the calculi was (3.1, 2.8, 2.5) mm. Of all the patients, there were no complications such as urine leakage, perirenal hematoma and postoperative infection. The hospital stay after operation was 3~5 d [average( 4.0±1.2) d]. There was no recurrence of calculi, hydronephrosis following up 1 and 3 months.
ConclusionsThe tubeless MPCNL has advantages of low risk, higher stone-free rate, less blood loss, less complications, quicker recovery. The tubeless MPCNL should be a safety and effective method for patients with upper urinary calculi, which could be worth clinical extensive application.
