[Complete penile rehabilitation of a patient with microphallia after correction of bladder exstrophy].

Bladder exstrophy is a complex of urogenital malformations, varying in severity from epispadias to classical bladder exstrophy. The main aim of correcting bladder exstrophy in childhood is to achieve urine continence with the prevention of upper urinary tract disorders and to provide penile reconstruction. However, by the time of puberty, it is not always possible to achieve optimal anatomical features of the penis, and usually, by the end of puberty, the penile length is no more than 7 cm, which subsequently leads to psychosocial and sexual problems during puberty. Neither patient, nor urologist in most cases do not satisfy final result of the treatment of exstrophy and a number of epispadias forms. A clinical case of the surgical rehabilitation of a patient after undergoing multi-stage surgical treatment for a congenital malformation of the genitourinary system is presented in the article. MATERIALS AND METHODS: At the admission, the size of the penis was 3 cm (microfallia), urethral meatus was located in the area of the penoscrotal junction. From 2016 to 2019, the patient underwent neofallos formation, urethroplasty, and implantation of prostheses in the neophallos. RESULTS: According to the results, urinary and sexual function was completely restored, as well as anatomical relationships and dimensional parameters of the genitals.

[Decellularized cadaveric human artery for substitution of connective tissue and smooth muscle defects on the example of tunica albuginea of penis (experimental work)]. / Ispol'zovanie detselliuliarizirovannoi trupnoi arterii cheloveka dlia zameshcheniia defektov soedinitel'notkannykh i gladkomyshechnykh struktur na primere belochnoi obolochki polovogo chlena (éksperimental'naia rabota).

AIM: To analyze experimentally the outcomes of xenotransplantation (cadaveric artery, decellularized cadaveric artery) for tunica albuginea defects repair. MATERIAL AND METHODS: The study included 60 chinchilla rabbits. Rabbits underwent local replacement of tunica albuginea. Animals were divided into 2 groups (group 1 - human cadaveric artery, group 2 - decellularized cadaveric artery). The result was considered after 7, 14 and 30 days postoperatively. RESULTS: Tendency to stasis, sludge-phenomenon and ultimately development of fibrosis of transplantation area were histologically observed in group 1 after 30 days. In group 2 luminal surface of decellularized artery was smoothed, fibrin and blood elements were absent. In group 1 mean level of C-reactive protein was 3.86±0.43, 1.17±0.2 and 0.73±0.16 mg/L after 7, 14 and 30 days respectively. In group 2 the same values were 0.33±0.03, 0.23±0.03 and 0.11±0.02 mg/L. Differences were significant (t =-46.28, t = -25.95, t = -14.84; p<0.0001).

[Buccal mucosa substitution urethroplasty in a patient with an extensive urethral stricture].

Urethral strictures are one of the most common reasons to see a urologist and are considered a socially significant disease. Management of urethral strictures is one of the challenging issues in urology. The article presents a case of a patient with extensive iatrogenic stricture of the penile urethra. The patient underwent penile augmentation urethroplasty using buccal mucosa resulting in the restoration of the whole length of the urethral lumen and non-obstructive urination according to uroflowmetry findings.

[Comparative effectiveness of Marmar technique and laparoscopic clipping of testicular vein in surgical treatment of varicocele in athletes].

INTRODUCTION: Varicocele is one of the most common diseases among men and a proven cause of male infertility, which is directly proportional to its clinical prominence. The aim To evaluate the immediate and long-term outcomes of different surgical methods to treat varicocele in athletes. MATERIALS AND METHODS: A total of 165 athletes were treated for varicocele. Of them, 82 patients (group 1) underwent varicocele surgery using Marmar technique and 83 patients (group 2) were treated by laparoscopic clipping of testicular vein (endoscopic analogue of Ivanissevitch open surgery). RESULTS: The incidence of postoperative complications and relapse at 6 months after surgery in groups 1 and 2 was 1.2% and 8.4%, and 4.9 and 14.5%, respectively. The study findings showed a statistically significant (p<0.05) improvement in the spermogram parameters in both groups compared with preoperative values. CONCLUSIONS: The length of hospital stay and postoperative rehabilitation period were shorter in patients after Marmars varicocelectomy than in patients of group 2. Besides, Marmar technique for varicocele was cost-effective and justified.
