[Operative treatment of kidney calculi]

262 cases of coral nephrolithiasis (CN) treated for the last 5 years (mean age 51.6 years) have been analysed. Of them, 46 (17.9%) patients have undergone 2 to 4 operations, 14 (5.4%) patients had bilateral nephrolithiasis. Open surgical interventions (section nephrolithotomy, pyelonephrolithotomy) were performed in 31 and 106 patients, respectively. All of them had a severe form K-3 or K-4. Extracorporeal shock-wave lithotrophy (ESWL) was conducted in 72 (27.5%) patients with coral concrements K-1, K-2. 'Mean number of the procedures per a stone was 4.2. Transcutaneous puncture nephrolithotripsy (TPNT) was made in 53 (20.2%) patients (K-2, K-3). The results of the treatment were assessed at discharge and 12 months after it. The efficacy of the treatment was judged by completeness of the stone elimination, postoperative complications and interventions to correct these complications. Open operations eliminated the stones completely in 71.2% patients, in combination with ESWL--in 91.6%, TPNT--in 78%, in combination with ESWL--in 94.5%. Efficacy of ESWL as monotherapy + stent reached 68.1%. Open operations entailed complications in 41.6% (of them 68.5% in section nephrolithotomy), TPNT--in 18.2%, ESWL--in 16.3%. Coral nephrolithiasis should be treated by skilled specialists in clinics furnished with modern facilities, combination of which minimizes traumatic complications and raises treatment efficacy.
