Kidney staghorn calculus1/21/2024 ![]() Risk factors such as metabolic disorders, recurrent urinary tract infections and/or congenital abnormalities of urinary tract are detected in 75-85% of children with urolithiasis. Urolithiasis in children occurs with the incidence of 0.1-5%. KrzemieÅ„, Grażyna Szmigielska, Agnieszka Jankowska-Dziadak, Katarzyna PaÅ„czyk-Tomaszewska, MaÅ‚gorzata Mini-PCNL combined ESWL may substitute the open operation and is the Mini-PCNL is effective and causes less trauma for un-hydronephrotic cata- staghorn renal calculi. ![]() The size and amount of left-over calculi in 3 patients (33.3%, 3/9) were increasing. Two (5.4%, 2/37) had calculus recurrence in 37 cases which calculi were completely removed before. Renal function re-investigation showed that 8 patients recovered and 2 improved in the 10 patients who had azotemia before. None of them had nephro-hydrops or stenosis. All the 46 patients were followed up for 4 to 48 months. Left-over calculi in 17 patients (8 patients after the first time mini-PCNL, 7 patients after second-look, and 2 patients after third-look) were treated by extracorporeal shock-wave lithotripsy (ESWL) and 8 were removed completely. Calculi in 1 of the 3 cases were completely removed by third-look mini-PCNL. Calculi in 10 patients (21.7%) were completely removed among the 20 patients who underwent second-look mini-PCNL. Calculus was completely removed in 18 patients (39.1%). The amount of blood ranged from 50 to 200 (mean=100) mL and no one needed blood transfusion. The operative time ranged from 140 to 280 (mean=190) min. The pervium in the 46 patients was successfully established by one-session puncturation with B-type ultrasonography guidance. Lithotripsy by air pressure path lithotripter and/or holmium laser was done when the pervium was established. ![]() Puncturation was guided by B-type ultrasound. The diameter of calculi ranged from 4.2 to 6.4 (mean=5.2) cm. There were mono- renal calculi in 38 patients (3 patients were the isolated renal calculi) while the other 8 combined opposite side upper urinary tract calculi. The clinical data of 46 cases (31 males and 15 females) treated by mini-PCNL were retrospectively analyzed. To evaluate the surgical techniques and clinical effects of mini-percutaneous nephrolithotomy (mini-PCNL) in the treatment of un-hydronephrotic cata- staghorn renal calculi. Gao, Ning Chen, He-Qun Qi, Lin Yang, Zhong-Qing Qi, Fan Zhang, Xiang-Yang In 6 patients (15 per cent) recurrent renal calculi developed, and 3 patients (8 per cent) had residual calculi during this period. The patients had been followed for an average of twenty months (four to one hundred and twelve months). Thirty-six of the 40 renal units (90 per cent) had improved or stable intravenous pyelograms postoperatively. ![]() In 6 patients (15 per cent) transient nephrocutaneous fistulas developed. Magnesium ammonium phosphate calculi were present in the majority of patients (67 per cent). Thirty-six (95 per cent) of the patients' preoperative urine cultures were infected, and postoperatively 35 of the cultures (88 per cent) were sterile. James, R Novick, A C Straffon, R A Stewart, B Hįorty anatrophic nephrolithotomies were performed in 38 patients between November, 1965, and December, 1977, to remove staghorn or branched renal calculi. Anatrophic nephrolithotomy for removal of staghorn or branched renal calculi. ![]()
