The tissue safety of a new shock wave generator, the Siemens C generator, was investigated in a porcine model. The tissue and functional effects of single treatments as well as retreatments were evaluated after 2 and 14 days. Quantitative morphologic and functional studies suggest that this device can be applied at its maximum energy up to 4000 shock waves (SW) without provoking damage that would lead to clinical concern. From this study, it appears justified to apply this device to patients suffering from stone disease to assess the clinical efficiency.

Aims The efficacy of the transurethral convective interstitial radiofrequency water vapor thermal ablation of the prostate with the Rezūm system for the treatment of male lower urinary tract symptom due to benign prostatic hyperplasia is well proven. The improvement of urodynamic parameters obtained from a simple uroflowmetry cannot measure the effect of water vapor injection on the bladder outlet obstruction. Methods This monocentric retrospective pilot study analyzes the data of pressure‐flow studies performed before and after 17 Rezūm procedures to answer the question whether thus obtained ablation of prostate tissue has a disobstructive effect on the bladder outlet. Results All the functional outcomes were consistently improved after the procedure, with a median flowrate increase of 5.1 ml/s (p = 0.0022) and a median postvoid residual urine (PVR) reduction of 100 ml (p = 0.0042). The prostate volume was reduced by 40% (p < 0.0001) and the median Bladder Outlet Obstruction Index (BOOI) reduction was 53.8 (p < 0.0001). Conclusions These data show that the possibility to significantly reduce the obstruction grade with even a single Rezūm procedure is concrete and seems to be independent from the degree of the obstruction grade.

Background: The most commonly used treatment modality for urethral strictures is the direct visual internal urethrotomy method according Sachse cold knife, but with low long-term success rate. Alternative method after failure is isurethroplasty with preputial flap or Buccal mucosa. The aim of this presentation is to report the efficacy of the Internal Urethrotomy with Holmium Laser (Sachse laser).Material and methods: We report three cases of urethral stenosis after trauma which treated with Internal Urethrotomy with Holmium Laser (Sachse laser) after failure of multiple treatments with Sachse cold knife. We evaluated and compared the uroflowmetry parameters before and after Sachse laser.Results: The average of uroflowmetry parameters before incision were: Q max 4.5 ml/sec, Q med 3 ml/sec. Voided Volume 323 cc, while after incision with Sachse laser were: Q max 30 ml/sec, Q med 12 ml/sec. Voided Volume 363 cc.No patients relapsed during follow-up time from 3 to 24 months.Conclusion: Even though these are only a few cases, we think that Sachse laser is a valid alternative after unsuccessful Sachse cold knife and before Urethroplasty, even in patients with urethral stricture after trauma.

Objective: To present a retrospective analysis on the oncological and functional outcomes of a single-center experience on a large series of extraperitoneal laparoscopic radical prostatectomies (eLRP) with an extended follow-up. Materials and methods: Herein we present a retrospective review of patients who underwent eLRP. Oncological and functional follow-up data were collected by means of outpatient visits and telephone interviews, assessing overall mortality and biochemical recurrence-free survival. Patients with clinical T4 stage prostate cancer (PCa), previous surgery for benign prostatic hyperplasia (BPH), previous androgen deprivation, radiotherapy, concomitant chemotherapy and/or experimental therapies, and with insufficient follow-up data were excluded. Preoperative data recorded were age, body mass index, ultrasound prostate volume, preoperative PSA and clinical stage of PCa. Operative data (operative time, nerve sparing technique and any perioperative complication) and pathological findings were obtained by consulting the surgical and pathological reports. Oncological and functional follow-up were collected during follow-up visits and telephone interview. Results: Between January 2001 and December 2019, overall 938 eLRP were performed at our Institution. The median follow-up was 132 months. 69.7% of the patients had complete dataset. The estimated overall biochemical recurrence (BCR)-free survival was 71.4% at 5 years and 58.9% at 10 years. Cancer specific survival was 84,5%. Erectile function was preserved in the most of patients as postoperative IIEF-5 score within 12 months after surgery was > 12 in the 82.1%. About the urinary incontinence, 0.76% of the patients presented severe incontinence (continued and persistent loss of urine) and 7.0% were mildly incontinent (using up to one pad per day). Conclusions; eLRP has shown oncological and functional results comparable to other minimally invasive techniques and to open radical prostatectomy (ORP), with favorable perioperative outcomes than the open technique and a reduced complication rate.
