RESUMO
INTRODUCTION: According to the recommendations of the European Association of Urology the presence of a suspicious lesion on MRI is an indication for both primary and secondary MR-targeted biopsies. At the same time, the Russian Society of Urologists recommends to perform mpMR/US fusion biopsy only in patients with a prior negative biopsy. In clinical practice, mpMR/US fusion and cognitive biopsies are the most frequently performed. However, when comparing them, contradictory data on detection of clinically significant prostate cancer is obtained. OBJECTIVE: to compare the detection rate of clinically significant prostate cancer performing cognitive and mpMR/US fusion biopsies. MATERIALS AND METHODS: Inclusion criteria: PSA >2 ng/mL and/or a positive DRE, and/or a suspicious lesion on TRUS, and PI-RADSv2.1 lesion more or equal 3. At first, "unblinded" urologist performed a transperineal mpMR/ultrasound fusion and saturation biopsy. Then "blinded" urologist obtained transrectal cognitive biopsy Clinically significant cancer was defined as ISUP more or equal 2. RESULTS: We enrolled 96 patients. Median age was 63 years, prostate volume - 47 cm3 and PSA - 6.82 ng/mL. MpMR/US fusion and cognitive biopsies were comparable in regard to the detection rate of clinically significant (32.3% vs 25.0%; p=0.264), clinically insignificant cancer (25.0% and 26.0%; p=0.869) and overall detection rate (57.3% and 51%;p=0.385). Both biopsies missed clinically significant cancer with equal frequency (5.2%; p=0.839). Histological efficacy also was comparable. The number of positive cores between mpMR/US fusion and cognitive biopsy was equal (34.1% and 31.1% respectively; p= 0.415). At the same time, no statistically significant difference was found with respect to maximum cancer core length (53.1% vs 47.7%, respectively; p=0.293). CONCLUSION: The results suggest that both cognitive and mpMR/US fusion biopsies are equally accurate diagnostic methods for clinically significant prostate cancer detection, thus their wider introduction into clinical practice is necessary.

INTRODUCTION: Some authors consider HoLEP a new gold standard for the surgical management of prostatic hyperplasia. The increasing utilization of holmium enucleation has led to the development of various modifications of this treatment modality, including the so-called enucleation as a single piece (HoLEP en bloc), which reduces the operative time and, according to some authors, facilitates acquiring new surgical technique by surgical trainees. AIM: To compare the effectiveness and safety of the traditional HoLEP and HoLEP en bloc. MATERIALS AND METHODS: The study comprised 227 BPH patients aged from 53 to 86 years old (mean - 61.38+/-5.09 years). HoLEP en bloc was performed in 114 patients, of whom 39 patients had prostate volume (Vpr) less than 80 cm3, and in 75 patients it was more than 80 cm3. The standard HoLEP was performed in 113 patients, of whom 41 patients had Vpr less than 80 cm3, and in 72 patients it was more than 80 cm3. RESULTS: Enucleation time: HoLEP - 48+/-12 min, HoLEP en-bloc - 35+/-10; morcellation time: HoLEP - 20+/-3 min, HoLEP en-bloc - 16+/-12; duration of urinary bladder drainage by a urethral catheter: HoLEP - 58+/-3 h, HoLEP en-bloc - 41+/-2; length of hospital stay: HoLEP - 5.93+/-0.39 days, HoLEP en-bloc - 4.45+/-0.35; bladder tamponade, urethrocystoscopy and coagulation of bleeding vessels: HoLEP-3, HoLEP en-bloc-1; infectious-inflammatory complications (prostatitis): HoLEP-3, HoLEP en-bloc-2; acute urinary retention, stress urinary incontinence: HoLEP-6, HoLEP en-bloc-2; stress urinary incontinence: HoLEP - 5, HoLEP en-bloc - 2. CONCLUSION: En bloc holmium enucleation of the prostate results in the reduction of enucleation and total operative time compared with traditional HoLEP due to the fast identification of the surgical capsule and the right layer. Using this technique can improve the effectiveness of learning holmium laser enucleation of the prostate by surgical trainees.

INTRODUCTION: With growing experience in the HoLEP, it can replace TURP as the "gold standard" for the surgical management of BPH, and therefore this technique is the most studied surgical modality. Despite the proven effectiveness of HoLEP in the treatment of patients with BPH, its widespread use has been associated with both intra- and postoperative complications. AIM: To improve the results of surgical management of patients with BPH. MATERIAL AND METHODS: The study comprised 310 patients who underwent HoLEP for BPH. HoLEP was performed using the Gillings technique. INCLUSION CRITERIA: presence of LUTS (Qmax<15 ml/s, Qav<10 ml/s, presence of residual urine, I-PSS score> 5, QoL score> 2), absence of an active inflammatory process of the urogenital organs. RESULTS: Intraoperative complications included severe hemorrhage in 16 (5.2%), the bladder wall injury in 17 (5.5%) and the ureteral orifice injury in 2 (0.6%) patients. 275 (88.7%) had no intraoperative complications. Early postoperative complications included fever in 4 (1.3%), the bladder tamponade that required cystoscopy and evacuation of blood clots in 7 (2.3%) and acute urinary retention in 36 (11.8%) patients. 263 (84.6%) patients had no postoperative complications. Long-term postoperative complications comprised urinary incontinence in 39 (12.6%) patients and urethral strictures requiring surgical treatment in 9 (2.9%) patients. There were no long-term complications in 262 (84.5%) patients. CONCLUSION: HoLEP is an effective and safe surgical modality for treating patients with BPH with minimal complications, suitable for any size of the prostate.

Results of 178 operations with extended D3 lymphadenectomy (study group) performed at the patients with stomach cancer are analyzed. Control groups consisted of 175 patients undergone operations with D2 lymphadenectomy, and 266 patients undergone surgery of typical extension. Study and control groups were similar according to prognostic factors. Indications for extended lymphadenectomy are formulated. It was demonstrated that short-term results in both group were equal. Safety of extended D3 lymphadenectomies wasalso confirmed. Extended D3 lymphadenectomies permitted to increase the respectability on 6.7%.
