[Treatment of ureterocele in children].

Twenty six patients (15 children and 11 adults) with ureterocele were treated. Heterotopic ureterocele prevailed over common forms in children while in adults--vice versa (66.7 and 33.3% versus 27.3 and 72.7%, respectively). Recurrences of ureterocele are rather frequent. Modified surgical correction of ureterocele is proposed which consists in intravesical mobilization of ureterocele together with a terminal part of the ureter followed by resection and its transverse re-implantation with antireflux defense. Such therapeutic policy facilitates performance of the operation and enhances reliability of the closing antireflux mechanism. Endoscopic correction of ureterocele with one-stage lithoextraction was made in 7 adult patients who had undergone transverse dissection of ureterocele, in large ureterocele--partial resection of the lower part. The residual upper part operates as a closing valve in filling of the urinary bladder. Long-term results (3-year follow-up maximum) were studied in 23 patients. Dissection of ureterocele with ureterocystoneostomy was associated with recurrences in 37.6% patients. The best results were achieved in plastic modified operations and endoscopic correction of ureterocele. A persistent clinical effect was seen in all the patients.

[Extracorporeal shock wave lithotripsy and recurrent urolithiasis]. / Distantsionnaia udarno-volnovaia litotripsii i retsidiv kamneobrazovaniia.

Changes in concentrations of total thyroxine (T4) and triiodothyronine (T3) in blood plasma, blood coagulation and prothrombin index (PI) 9 days after exposure to extracorporeal shock-wave lithotripsy (ESWL) were studied in patients with urolithiasis. Urolithiasis patients with chronic pyelonephritis running with non-severe renal pain had often elevated concentrations of T3, T4 and blood coagulation. On day 9 after ESWL plasma concentration of T3 and coagulation decreased while T4 concentration and PI rose. The analysis of 4-year follow-up after ESWL demonstrates that high levels of T4 and PI on day 9 after ESWL may contribute to development of recurrent urolithiasis.

[Effects of antihypertensive therapy on renal function in nephrogenic hypertension]. / Vliianie gipotenzivnoi terapii na funktsiiu pochek pri nefrogennoi gipertenzii.

Radionuclide tracing was performed to study renal function before and after hypotensive therapy in 95 patients suffering from nephrogenic hypertension with renal failure. It is shown that if hypotensive therapy in such patients brings about a blood pressure fall more than 25% of the initial blood pressure, renal function declines, the suppression being especially evident in severe renal insufficiency.

[Effects of shock-wave lithotripsy (ESWL) on electrolytic and hormonal balance in nephrolithiasis patients]. / Vliianie udarno-volnovoi litotripsii (DUVL) na élektrolitnyi i gormonal'nyi balans u bol'nykh pochechnokamennoi bolezn'iu.

Blood concentrations of parathyroid hormone, aldosterone, hydrocortisone, Na+, K+, Ca2+, 24-h urine concentration of Ca2+, blood pressure were measured on day 3 and 7 after extracorporeal shock-wave lithotripsy. A total of 54 patients with nephrolithiasis (NL) were examined. In NL patients with hypertension the above lithotripsy led to a fall in pressure by 15-20%, to correction of initial hormonal and electrolytic unbalance. There were marked changes in the levels of parathyroid hormone, total Ca2+ in the blood and 24-h urine.

[The prognosis of the efficacy of extracorporeal shockwave lithotripsy of the kidneys and ureters]. / Prognozirovanie éffektivnosti distantsionnoi udarnovolnovoi litotripsii pochek i mochetochnikov.

A retrospective analysis of the data on 300 patients revealed a relationship between basic clinical and history evidence, location of the concrement and efficacy of a single lithotripsy. The author presents factors influencing concrement disintegration. Basing on the relations between efficacy of lithotripsy and clinical signs three-score system for estimation of each sign is proposed. The highest effect of the concrement fragmentation occurred within 10 scores (in 97.1% of the patients). The score above 16 is indicative of lowering efficacy of lithotripsy. This system of calculation is efficient in prognostication of efficacy of extracorporeal impulse lithotripsy of the kidneys and ureters.

[The diagnosis and treatment of diseases of dystopic kidneys]. / Diagnostika i lechenie zabolevanii distopirovannykh pochek.

The analysis is presented of 64 surgical cases of affected dystopic kidneys. Of these, 34 had urolithiasis, 6 renal tumors, 10 hydronephrosis, 14 chronic pyelonephritis. The principal diagnostic facility was radionuclide renal scintigraphy. On deciding on the operative treatment, additional use of angiography, cystography and other methods is advisable. Diagnostic findings and treatment variants are described.

[Diagnostic prospects of angiography in pyo-destructive processes in the kidney]. / Diagnosticheskie vozmozhnosti angiografii pri gnoino-destruktivnykh protsessakh v pochke.

The article is devoted to search for indications and more exact differential diagnostic criteria of angiographic methods of diagnosis of pyo-inflammatory diseases of the kidney. Of most informative value is the selective renal arteriography and pharmacophlebography which gave more exact differential diagnostic criteria.
