Long-Term Oncological Outcomes after Nerve-Sparing Robot-Assisted Radical Prostatectomy for High-Risk Localized Prostate Cancer: A Single-Center, Two-Arm Prospective Study.

AIMS: To compare the oncological outcomes of patients with high-risk localized prostate cancer undergoing nerve-sparing and non-nerve-sparing robot-assisted radical prostatectomy (RARP). METHODS: Between November 2002 and December 2018, we prospectively recorded the data of patients undergoing RARP for high-risk localized prostate cancer (PCa) at our tertiary referral center. NSS (nerve-sparing surgery) was carefully offered on the basis of the preoperative clinical characteristics of the patients and an intraoperative assessment. The patients were stratified into two groups: nerve-sparing and non-nerve-sparing groups (yes/no). Radical prostatectomies were performed by 10 surgeons with a robot-assisted technique using a daVinci® surgical system. The primary oncological outcome evaluated was biochemical recurrence (BCR). The secondary oncological outcomes assessed were positive surgical margins (PSMs) and cancer-specific survival (CSS). RESULTS: A total of 779 patients were included in the study: 429 (55.1%) underwent NSS while 350 (44.9%) underwent non-NSS. After a mean (±SD) follow-up of 192 (±14) months, 328 (42.1%) patients developed BCR; no significant difference was found between the NSS and non-NSS groups (156 vs. 172; p = 0.09). Both our univariable and multivariable analyses found that the nerve-sparing approach was not a predictor of BCR (p > 0.05). Kaplan-Mayer survival curves for BCR showed no significant difference among the non-NSS, unilateral NSS, and bilateral NSS groups (log rank test = 0.6). PSMs were reported after RARPs for 254 (32.6%) patients, with no significant difference between the NSS and non-NSS group (143 vs. 111; p = 0.5). In the subgroup of 15 patients who died during the follow-up period, mean (±SD) CSS was 70.5 (±26.1) months, with no significant difference between the NSS and non-NSS groups (mean CSS: 70.3 vs. 70.7 months). CONCLUSIONS: NSS does not appear to negatively impact the oncological outcomes of patients with high-risk PCa. Randomized clinical trials are needed to confirm our promising findings.

Posterior reconstruction during robotic-assisted radical cystectomy with intracorporeal orthotopic ileal neobladder: description and outcomes of a simple step.

A posterior reconstruction (PR) might improve the fluidity and delicacy of the maneuvers related to the neovesico-urethral anastomosis during robotic-assisted radical cystectomy (RARC). Our objective is to describe in detail the surgical steps of PR and to assess its feasibility and functional outcomes. The data regarding patients undergoing a totally intracorporeal RARC with neobladder and PR for high-grade and/or muscle-invasive urothelial cancer of the bladder at Karolinska University Hospital between October 2015 and November 2016 by a single surgeon (PW) were reviewed. Prior to the anastomosis, a modified posterior Rocco's repair involving the Denonvillier's fascia, the rhabdosphincter, and the posterior side of the ileal neobladder neck was performed. The steps are shown in a video at https://doi.org/10.1089/vid.2019.0029 . The primary outcome was urinary continence; the secondary outcomes were urinary leakage, intermittent catheterization, and complications related to the reconstructive steps. Eleven male patients with a median age and BMI of 67 years and 24, respectively, underwent RARC with PR associated to the neovesico-urethral anastomosis. Overall and posterior reconstruction time were 300' (195-320) and 6' (4-7), respectively. The daytime and nighttime continence rates were 100% and 44% at 12 months, respectively; the median pad weight was 3.5 g and 108 g at daytime and nighttime, respectively. One urinary leakage from the urethrovesical anastomosis was treated conservatively. Two patients perform intermittent catheterization. The posterior reconstruction during RARC is safe and feasible, providing good continence rates. It supported a careful suturing of the anastomosis as well as an uncomplicated catheter placement.

American Confederation of Urology (CAU) experience in minimally invasive partial nephrectomy.

PURPOSE: To describe the perioperative and oncology outcomes in a series of laparoscopic or robotic partial nephrectomies (PN) for renal tumors treated in diverse institutions of Hispanic America from the beginning of their minimally invasive (MI) PN experience through December 2014. METHODS: Seventeen institutions participated in the CAU generated a MI PN database. We estimated proportions, medians, 95 % confidence intervals, Kaplan-Meier curves, multivariate logistic and Cox regression analyses. Clavien-Dindo classification was used. RESULTS: We evaluated 1501 laparoscopic (98 %) or robotic (2 %) PNs. Median age: 58 years. Median surgical time, warm ischemia and intraoperative bleeding were 150, 20 min and 200 cc. 81 % of the lesions were malignant, with clear cell histology being 65 % of the total. Median maximum tumor diameter is 2.7 cm, positive margin is 8.2 %, and median hospitalization is 3 days. One or more postoperative complication was recorded in 19.8 % of the patients: Clavien 1: 5.6 %; Clavien 2: 8.4 %; Clavien 3A: 1.5 %; Clavien 3B: 3.2 %; Clavien 4A: 1 %; Clavien 4B: 0.1 %; Clavien 5: 0 %. Bleeding was the main cause of a reoperation (5.5 %), conversion to radical nephrectomy (3 %) or open partial nephrectomy (6 %). Transfusion rate is 10 %. In multivariate analysis, RENAL nephrometry score was the only variable associated with complications (OR 1.1; 95 % CI 1.02-1.2; p = 0.02). Nineteen patients presented disease progression or died of disease in a median follow-up of 1.37 years. The 5-year progression or kidney cancer mortality-free rate was 94 % (95 % CI 90, 97). Positive margins (HR 4.98; 95 % CI 1.3-19; p = 0.02) and females (HR 5.6; 95 % CI 1.7-19; p = 0.005) were associated with disease progression or kidney cancer mortality after adjusting for maximum tumor diameter. CONCLUSION: Laparoscopic PN in these centers of Hispanic America seem to have acceptable perioperative complications and short-term oncologic outcomes.

Health and quality of life in urology: issues in general urology and urological oncology.

OBJECTIVES: Frequently, the term "quality of life" has been used to justify personal and professional decisions in all fields of medicine. Nowadays, quality of life studies are based on development and validation of sensitive measures of patient outcomes, incorporating functional status and perceived health status. Thus, quality of life has become an outcome as important as survival and effectiveness. METHODS: A systematic review using Pubmed and Medline was performed, searching for papers concerning health related quality of life and urology. The most relevant articles where questionnaires and interviews were described and validated were listed. RESULTS: Based on psychometric properties, a search between 1970 and 2007 identified a total of 25 recommendable articles with generic inventories and specific modules that have been developed, validated and used in clinical practice or research. Historical aspects, quality of life concepts, validation of questionnaires and structured interviews, and most used instruments in generic health-related quality of life, general urology and urological oncology have been discussed. CONCLUSIONS: A brief review of historic background of health related quality of life and urology was performed.

[Laparoscopic management of symptomatic urachal anomalies]. / Manejo laparoscópico de las anomalías sintomáticas del uraco.

INTRODUCTION: Acquired urachal anomalies are a rare pathology. Gold-standard treatment for this clinical situation remains the resection of the urachus in its entire tract with or without partial resection of the bladder. Our aim is to up-date authors's experience in the minimally invasive surgical treatment of acquired urachal disease. METHODS: From 2001 to 2007, 14 patients were operated for acquired urachal disease at our institution. A three portal technique previously described by the authors was employed. The diagnosis of acquired uracal disease was confirmed in all cases and the resection of the urachus in its entire tract performed in cephalocaudal direction onto the bladder. Operative and demographic data was prospectively collected and analysis retrospectively performed. RESULTS: Mean operative time was 63 minutes (45,110), minimal blood loss, and no conversions to open surgery or perioperative complications were verified. The majority of the patients were discharged in the first 24 hours. At a follow-up of 22 months no recurrences of urachal pathology recurrences have been verified. CONCLUSIONS: Laparoscopy plays a significant role in the management of symptomatic urachus anomalies. It allows objective confirmation of clinical diagnosis and adequate resection of the urachus in a safe and efficient fashion, while providing the well-known advantages of minimally acces surgery. Preoperative evaluation work-up has minimal impact of therapeutical decision.

Manejo laparoscópico de las anomalías sintomáticas del uraco / Laparoscopic management of symptomatic urachal anomalies

Introducción: Las anomalías uracales son una patología poco frecuente, el tratamiento aceptado consiste en la resección del uraco en todo su trayecto con o sin resección parcial de la vejiga. Nuestro objetivo es actualizar nuestra experiencia en el tratamiento de anomalías sintomáticas del uraco mediante cirugía de mínimo acceso. Pacientes y Métodos: Entre los años 2001 y 2007 se operaron 14 pacientes con anomalías adquiridas sintomáticas del uraco en nuestra institución. Se utilizó una técnica de tres portales previamente descrita por los autores, mediante la cual se realiza abordaje de la cavidad abdominal, confirmación del diagnóstico clínico inicial y resección del uraco en todo su trayecto en sentido cráneo caudal hasta la vejiga. Los datos demográficos y operatorios fueron recolectados de manera prospectiva y el análisis se realizó retrospectivamente. Resultados: El tiempo quirúrgico promedio fue de 63 minutos (45, 110) con sangrado mínimo, sin casos de conversión ysin complicaciones asociadas a la técnica. La gran mayoría de los pacientes egresó durante las primeras 24 horas. En un tiempo promedio de seguimiento de 22 meses no se han reportado recurrencias de la patología uracal. Conclusión: La laparoscopia juega un importante papel en el manejo de las anomalías sintomáticas del uraco, ya que permite confirmar el diagnóstico clínico y realizar la resección del uraco de manera segura y eficaz, aportando las ya conocidas ventajas de la cirugía de mínimo acceso. Los estudios de evaluación preoperatoria son de poca utilidad en la confirmación de esta patología (AU)
