New methods of X-ray surgical diagnosis and treatment of varicocele in children and adolescents

The authors studied 520 patients with left-sided varicocele by left-sided phleborenotesticulography of Doppler ultrasonography, tensiometry of the left renotesticular venous system, blood gas composition, hormonal parameters, and etc. They present rationale for and evidence illustrations of aortomesenteric compression of the left renal vein, left-sided phleborenal hypertension prior to and after surgery for endovascular occlusion of the left testicular vein, before and following intervenous proximal testiculoiliac venous bypass surgery. The data of andrological dysfunction in patients with varicosis of the pampiniform plexus and spermatic cord (varicocele) are presented. An algorithm of examination and treatment of this cohort of patients, by using both miniinvasive techniques (for X-ray endovascular occlusion of the temporal veins under local anesthesia) and high tech operations using microsurgical techniques (testiculoiliac venous anastomosis), is outlined.     

Renal artery aneurysms in children]

Renal artery aneurysms were diagnosed in 11 patients (9 boys) aged 1 to 14. The examinations were carried out for vasorenal hypertension in 4 cases, for bladder-ureter reflux, hematuria, nephroptosis in 4, ureterohydronephrosis in 2 cases, and for interstitial nephritis. Aneurysms of the major trunk of the renal artery, mostly oval-shaped, 11 x 14 to 25 x 28 mm in size, were detected in 4 patients, intrarenal aneurysms 2 x 3 to 5 x 6 mm in size in 7 cases. The share of aneurysms among uronephrologic conditions in children was found to be 1.54%, among vasorenal hypertension cases, 4.3%. Vasorenal hypertension is the main optional sign of aneurysms of the main trunk of the renal artery, whereas for intrarenal aneurysms such sign is hematuria.
