CLINICAL RESEARCH

In the paper results of examination and treatment of 27 patients suff ering from recurrent phosphate nephrolithiasis which were treated at the Research Institute of Urology were analyzed. Patients with chronic renal failure grade II-III and hyperparathyroidism were excluded. Along with overall assessment of renal function (glomerular fi ltration rate, daily protein excretion, inorganic phosphate excretion etc.) and spectral analysis of excreted calculi, all patients underwent assessment for bone mineral density of calcaneal tuber by osteodensitometry using Calscan device (Lund, Sweden).

To evaluate the eff ects of Botulinum Toxin Type A (BTXA) injected into the external urethral sphincter in patients with dctrusorexternal sphincter dyssynergia caused by spinal cord injury. Th e eff ects of transurethral (TU) versus transperineal (TP) BTXA injection were compared. 17 male patients with detrusor-sphincter dyssynergia were divided into 2 groups: TU group and TP group. Four points injection method was employed with allocation by cystoscope in TU group. 1 point injection method percutaneous around the urethral was employed with allocation by digital rectal examination.
