Efficacy and safety of the EMS Swiss LithoClast® Trilogy for PCNL: results of the European multicentre prospective study on behalf of European Section of UroTechnology.

PURPOSE: PCNL requires a lithotrite to efficiently break stones, and some devices include active suction to remove the fragments. We set out to determine the efficacy and safety of the Swiss LithoClast® Trilogy, in a prospective European multicentre evaluation and compared it to published stone clearance rates for Trilogy based on surface area (68.9 mm2/min) and using the 3D calculated stone volume (526.7 mm3/min). METHODS: Ten European centres participated in this prospective non-randomized study of Trilogy for PCNL. Objective measures of stone clearance rate, device malfunction, complications and stone-free rates were assessed. Each surgeon subjectively evaluated ergonomic and device effectiveness, on a 1-10 scale (10 = extremely ergonomic/effective) and compared to their usual lithotrite on a 1-10 scale (10 = extremely effective). RESULTS: One hundred and fifty seven PCNLs using Trilogy were included (53% male, 47% female; mean age 55 years, range 13-84 years). Mean stone clearance rate was 65.55 mm2/min or 945 mm3/min based on calculated 3D volume. Stone-free rate on fluoroscopy screening at the end of the procedure was 83%. Feedback for suction effectiveness was 9.0 with 9.1 for combination and 9.0 for overall effectiveness compared to lithotrite used previously. Ergonomic score was 8.1, the least satisfactory element. Complications included 13 (8.2%) Clavien-Dindo Grade II and 2 (1.3%) Grade III. Probe breakage was seen in 9 (5.7%), none required using a different lithotrite. CONCLUSIONS: We have demonstrated that Trilogy is highly effective at stone removal. From a user perspective, the device was perceived by surgeons to be highly effective overall and compared to the most commonly used previous lithotrite, with an excellent safety profile.

Orthotopic bladder substitution: Surgical aspects and optimization of outcomes.

Objectives: Orthotopic bladder substitution (OBS) is a management option for urinary diversion in men and women undergoing cystectomy. The aim of the procedure is to provide a functional continent urinary reservoir of adequate capacity, compliance and low pressure. We have provided a narrative review of the existing literature and highlighted areas where improvement and standardization can be recommended. Methods: Literature search included database search for publications from January 1970 to November 2020, using keywords including OBS, bladder reconstruction, neobladder, radical cystectomy, robotic cystectomy, intracorporeal neobladder, surgical technique, patient selection and outcomes. Results: Due to various factors including indications, operative technique and risk of complications, OBS is an enormous undertaking and commitment for patients, surgeons and health professionals involved in the care pathway. The main considerations for patient selection, the technical elements of the procedure and the rationale behind these are discussed. Previously considered to be a choice for a select few, the inclusion criteria have expanded over the last decade. Similarly, surgical techniques including the choice and configuration of bowel segments, construction of anastomosis and nerve or organ sparing procedures have evolved over the years. Minimally invasive laparoscopic and robotic assisted surgery has added further perspectives to the existing literature on OBS. Understanding the principles of operative techniques and assessing the best evidence to influence patient management is crucial as it has a major impact on clinical outcomes. Peri- and post-operative care, focused on the prevention of complications and morbidity, affects long-term functional and oncological outcomes, which ultimately dictates the quality of life. Conclusions: This concise overview of OBS literature highlights the importance of pre-operative, peri-operative, and post-operative aspects with regards to the optimization of patient care. To achieve the best results, meticulous attention should be paid in all these areas, surgical and multi-disciplinary. Patient education and counseling, with shared decision making are central to the success of the procedure.

Should assessment of penetrative sexual activity be used as the treatment arbiter in the management of Peyronie's disease?

Peyronie's disease is an inflammatory disorder, which causes thickening of the tunica albuginea of the penis. Peyronie's disease has a variable natural history and the assessment and management of the disease has yet to be standardised. The case notes of 97 patients with a diagnosis of Peyronie's disease were retrospectively reviewed at a single tertiary referral centre. Patients who were able to achieve sexual penetrative activity to the satisfaction of both partners were managed conservatively. Patients who were unable to achieve penetrative sexual activity were given intra-cavernosal prostaglandin, with those achieving a satisfactory erection being offered appropriate surgical intervention. The mean age at presentation was 50 years (range 18-82). A total of 59 (61%) men were able to have penetrative sex at the time of presentation. Following initial conservative management, only five (8%) of this group had disease progression, which stopped them from being able to penetrate. In all 38 (39%) men who were not able to penetrate at presentation were offered surgical intervention. In all 24 (63%) of these men chose to have surgical intervention. Tunical plication resulted in the ability to penetrate in 77% of men choosing this option whereas only 46% of men undergoing autologous saphenous vein grafting were able to have penetrative sex. Assessment of penetrative sexual function is an essential component of the management of patients with Peyronie's disease. This enables appropriate counselling with respect to possible conservative management or the most appropriate surgical intervention. The majority of patients with Peyronie's disease can achieve sexual penetrative activity, many without surgical intervention.
