[Results of transcutaneous nephrolithotripsy using the combined lithotriptor "2 in 1" "Swiss Lithoclast Master"].
The aim of the study was to determine frequency of infectious-inflammatory complications regarding the duration of transcutaneous nephrolithotripsy (TCNL). Two groups of nephrolithiasis patients were compared. Group 1 consisted of 37 nephrolithiasis patients aged 20 to 78 years (15 males, 22 females). Size of the concrements ranged from 1.8 to 4.9 cm. They underwent contact lithotripsy performed by an ultrasound lithotriptor. Group 2 consisted of 22 patients aged 34 to 74 years (11 males and 11 females). Nephroliths were 2.0 to 8.5 cm in size. Group 2 patients underwent combined contact pneumatic and ultrasound lithotripsy on a novel Swiss LithoClast Master unit. Elimination of the nephroliths was observed in 27 (72.9%) patients of group 2 and in 19 (86.3%) patients of group 2. Residual calculi were detected in 10 (27%) patients of group 1. Surgery lasted 66 to 140 min (mean 81.2) and 40 to 120 min (mean 58.5 min) in groups 1 and 2, respectively. Pyelonephritis activity was registered in 24 (77.4%) and 3 (13.6%) patients, respectively. Thus, in percutaneous lithotripsy of large stones, frequency of inflammatory complications depends not only on technical faults and initial bacteriuria, but also on the duration of the operation. If surgical intervention took more than 60 min, frequency of the infectious-inflammatory complications increased 1.6-fold. Utilization of the lithotriptor Swiss LithoClast Master raises efficiency, accelerates destruction and evacuation of stones.
