Diagnostics and correction of metabolic disorders in patients with recurrent urolithiasis after endoscopic removal of stones

The article is devoted to the problem of kidney stones. The authors provide the results of a study of 107 men aged 48 to 76 years, were divided into three groups – primary and two control groups. The main and the first control group consisted of 40 patients with recurrent urolithiasis without urinary tract obstruction after endoscopic stone removal and partial androgen deficiency. The second control group consisted of 27 healthy men aged 48 to 70 years. Patients for one year he was promoted endoscopic removal of urinary stones: transurethral nephrolithotripsy – 55 patients, and percutaneous nephrolithotripsy – 25. After discharge from hospital all patients had a diagnosis and correction of metabolic disorders using physical-chemical and biochemical indicators of urine and blood. To study the mineral composition and structural-textural features of urinary stones and their fragments after surgical interventions were performed: x-ray diffraction, infrared spectroscopy, polarization and electron microscopy. Was carried out following the relapse of urolithiasis: patients of the main group received pathogenetic androgen therapy as monotherapy, and patients in the control group conventional treatment (antibiotics, spasmolytic, herbal remedies). The results of therapy and follow-up care for 6 years showed a low recurrence of stone formation in patients of the main group and highest in the control. Age-related decline in androgen levels in men may be an additional factor in stone formation. Pathogenic androgen replacement therapy leads to normalization of the content of lithogenic substances in the blood and urine, as well as physico-chemical properties of urine, thereby reducing the process of stone formation

Extensive penile skin necrosis after surgery for Peyronie's disease

The clinical case represents the surgical correction of postoperative complications in a patient with Peyronie's disease. The patient underwent flap corporoplasty using an autovein. The late postoperative period in the patient was complicated by extensive necrosis of the penile skin, which required repeated surgery as follows. The first stage of surgical treatment was performed by excision of necrotic tissues of the penile skin. Within 10 days of the postoperative period, chymotrypsin with an ointment containing dioxomethyltetrahydropyrimidine with chloramphenicol was applied to the penile wound surface to prepare the wound for subsequent skin autotransplantation. Further, within 5 days, the polymeric drainage sorbent «Aseptisorb DT» was applied to the wound surface until the wound was cleansed and granulation tissue was formed. The second stage of the surgical treatment performed penile skin replacement plasty with a free perforated skin graft taken from the patient's femoral surface

THE OPERATIVE CYSTOSCOPE WITH JOYSTICK CONTROL MECHANISM OF FLEXIBLE TOOLS INSERTED INTO THE URINARY BLADDER AND THE URETER

The authors developed an operative cystoscope with joystick control mechanism of ureter catheters and other flexible tools. This construction allowed control of flexible tools inserted into the bladder and the ureter in various directions, thus providing a necessary observation of the operative field at endoscopic operations on the bladder and ureter. This was one of the factors, which determined the operation success

One-time use of a free perforated cutaneous autograft during the surgical treatment of the oleogranuloma of the penis (clinical case)

A clinical case of oleogranuloma of the penis is presented. The article outlines the relevance of this problem, which has increased in recent years due to the emergence of new cases. current and treatment of this problem. The authors describe the diagnosis of oleogranuloma of the penis and the stages of its removing with one-time use of free perforated cutaneous autograft. It was the optimal method of surgical treatment in this case
