[Subtotal resection of ureterocele].

After a review of the diagnostic and therapeutic possibilities of ureterocele, the authors' own experience with transvesical subtotal resection is presented. After the resection of the ureterocele, two-third of the patients were free of complaints and symptoms, their pyuria ceased and subsequent intravenous pyelography showed normal conditions.

[Kidney hypoplasia and hypertension].

The basis of the examination is a clinical material of 14 years (from 1960 to 1973) of the urological clinic of the Medical University "Semmelweis", consisting of 160 patients with renal hypoplasia. In 116 of these cases a nephrectomy was performed. The average postoperative observation time was 7.8 years. By removal of the hypoplastic kidney the hypertension could be successfully influenced in 72% of the cases and in 16% moderately; in 12% of the patients the high blood pressure remained unchanged also after the intervention. On account of the recognition resulting from the examinations that by the hypoplastic kidney alone no increase of the blood pressure is caused, but the developmental anomaly forms a basis for the development of the hypertension, is emphasized that the early removal of this abnormally developed kidney is by all means indicated.

[Effect of urinary transport function on the development of kidney calculi].

The formation of renal calculus is, according to the currently accepted view, a polyetiological process whose most important components are the composition of the urine and urinary stasis. The second of these factors is discussed. The importance of anatomical lesions is indicated by the finding of a hindrance of flow in 66 of the 100 patients operated for renal calculus. The stasis may, however, have some functional cause, too. X-rays revealed two types of hypomotility: a temporary, or in certain parts constant, lack of contractions and sluggish contractions of normal frequency. Temporary lack or sluggishness of contraction promotes calculus formation because the physiological pyelo-calicous reflux which occurs in three quarters of the intact cases is lacking. These refluxes counteract sedimentation and together with the orthostatic emptying are the most effective factors preventing the retention of calculus nuclei.
