Abstract

Contemporary minimally invasive surgical (MIS) treatment options of patients with male Lower Urinary Tract Symptoms (LUTS) in men with prostate glands >80 mL include Holmium Laser Enucleation Prostate (HoLEP), Thulium laser VapoEnucleation Prostate (ThuVEP), and Laparoscopic (LSP) or Robotic-Assisted Simple Prostatectomy (RASP). Implementing new laser technologies is costly, and the steep learning curve of these laser techniques limit their wide range use. This promoted the use of LSP and RASP in centers with readily established laparoscopy or robotic surgery programs. The aim of this study is to review case and comparative series of RASP. We systematically reviewed published data from 2008 to 2020 on RASP and have identified 26 non-comparative and 9 comparative case series. RASP has longer operation time but less time spent in hospital and less blood loss. The outcomes of improvements in symptom score, post-voiding residual urine (PVR), postoperative PSA decline, complications, and cost are similar when compared to open and laser enucleation techniques. These outcomes position RASP as a viable MIS treatment option for patients with male LUTS needing surgical treatment for enlarged prostates. Nevertheless, prospective, randomized controlled trials (RCTs) with multicenter and large sample size are needed to confirm the findings of this systematic review.

Abstract

Objectives: To analyze the impact of neoadjuvant chemotherapy on survival and recurrence patterns in muscle‐invasive bladder cancer after robot‐assisted radical cystectomy. Materials and methods: The International Robotic Cystectomy Consortium database was reviewed to identify patients who underwent robot‐assisted radical cystectomy for muscle‐invasive bladder cancer between 2002 and 2019. Survival outcomes, response rates, and recurrence patterns were compared between patients who received neoadjuvant chemotherapy and those who did not. Survival distributions were estimated using Kaplan–Meier analyses and compared using the log‐rank test. Results: A total of 1370 patients with muscle‐invasive bladder cancer were identified, of whom 353 (26%) received neoadjuvant chemotherapy. After a median follow‐up of 27 months, neoadjuvant chemotherapy recipients had higher 3‐year overall survival (74% vs 57%; log‐rank P < 0.01), 3‐year cancer‐specific survival (83% vs 73%; log‐rank P = 0.03), and 3‐year relapse‐free survival (64% vs 48%; log‐rank P < 0.01). Neoadjuvant chemotherapy was a predictor of higher overall survival, cancer‐specific survival, and relapse‐free survival in univariate but not multivariate analysis. Pathological downstaging (46% vs 23%; P < 0.01), complete responses (24% vs 8%; P < 0.01), and margin negativity (95% vs 91%; P < 0.01) at robot‐assisted radical cystectomy were more common in the neoadjuvant chemotherapy group. Neoadjuvant chemotherapy recipients had lower distant (15% vs 22%; P < 0.01) but similar locoregional (12% vs 13%; P = 0.93) recurrence rates. Conclusions: In this analysis from a large international database, patients with muscle‐invasive bladder cancer who received neoadjuvant chemotherapy before robot‐assisted radical cystectomy had higher rates of survival, pathological downstaging, and margin‐negative resections. They also experienced fewer distant recurrences. [ABSTRACT FROM AUTHOR]

Abstract

Contralateral adrenal metastases from renal cell carcinomas are not commonly seen. To our knowledge, we are presenting the first case of extraadrenal metastasis in the English literature, from the contralateral RCC 6 months after radical nephrectomy. Patient was treated with robotic right adrenalectomy for continuous growing of a de novo right adrenal mass of 6 × 4 × 3 cm in diameter. Tissue between vena cava, renal capsule, and inferior diaphragmatic surface was removed en block. Pathological evaluation revealed renal cell carcinoma within the fatty tissue abutting the adrenal capsule from outside with negative surgical margins. Our experience dictates that removing adrenal tissue only after identifying the adrenal borders may sometimes result in insufficient tumor removal. Therefore, adrenal containing tissue within the anatomic boundaries should be removed en block, if surgical removal is planned for metachronous tumor metastasis in the treatment of renal cell carcinoma.

Article Subject, urologic and male genital diseases
Abstract

There has been an increase in the number of individuals seeking testosterone (T) replacement treatment (TRT) due to a decrease in their blood T levels. Prostate cancer (PCa) is also an important issue in the same age group. However, we, urologists, are anxious about PCa development after T treatment. This is because it has been assumed that T may cause PCa or exacerbate insidious PCa which is already present. In this paper, recent developments regarding the relationship between serum levels of sex hormone and prostate tissue, the causal relationship between T and development of PCa, the effect of TRT on the group of patients who are at high risk of developing PCa, the suitability of TRT for patients who have already been diagnosed with PCa, and the effect of TRT on serum prostate-specific antigen level are analyzed.

Kaplan-Meier curves were used to depict recurrence-free survival (RFS), disease-specific survival (DSS), and overall survival (OS). Multivariate stepwise Cox regression models were used to identify variables associated with RFS and OS.Results: Four hundred seventy-one patients (18%) with pT0 were identified. Median age was 68 years (interquartile range (IQR) 60-73), with a median follow up of 20 months (IQR 6-47). Thirty-seven percent received neoadjuvant chemotherapy and 5% had pN+ disease. Seven percent of patients experienced disease relapse; 3% had local and 5% had distant recurrence. Most common sites of local and distant recurrences were pelvis (1%) and lungs (2%). Five-year RFS, DSS, and OS were 88%, 93%, and 79%, respectively. Age (hazards ratio [HR] 1.05, 95% confidence interval [CI] 1.01-1.09, P = 0.02), pN+ve (HR 11.48, 95% CI 4.47-29.49, P < .01), and reoperations within 30 days (HR 5.53, 95% CI 2.08-14.64, P < .01) were associated with RFS. Chronic kidney disease (HR 3.24, 95% CI 1.45-7.23, P < .01), neoadjuvant chemotherapy (HR 0.41, 95% CI 0.18-0.92, P = .03), pN+ve (HR 4.37, 95% CI 1.46-13.06, P < .01), and reoperations within 30 days (HR 2.64, 95% CI, 1.08-6.43, P = .03) were associated with OS.Conclusions: Despite pT0 status at RARC, 5% had pN+ disease and 7% of patients relapsed. Node status was the variable strongest associated with RFS and OS in pT0. [ABSTRACT FROM AUTHOR]

Abstract

Objectives: We aimed to modify the Briganti 2019 nomogram and to test whether it is valid for patients who were diagnosed with prostate cancer through in-bore prostate biopsies., Methods: Data for 204 patients with positive multiparametric prostate MRI and prostate cancer identified either by mpMRI-cognitive/software fusion or in-bore biopsy and who underwent robot-assisted radical prostatectomy and extended pelvic lymph node dissection between 2012 and 2023 were retrospectively analyzed. The Briganti 2019 nomogram was applied to the mpMRI-cognitive/software fusion biopsy group (142 patients) in the original form, and then, two modifications were tested for the targeted component. Original and modified scores were compared. These modifications were adapted for the in-bore biopsy group (62 patients). The final histopathologic stage was regarded as the gold standard., Results: Nodal metastases were identified in 18/142 (12.6%) of mpMRI-cognitive/software fusion biopsy patients and 8/62 (12.9%) of the in-bore biopsy patients. In the mpMRI-cognitive/software fusion biopsy group, tumor size/core size (%) of targeted biopsy cores and positive core percentage on systematic biopsy were significant parameters for lymph node metastasis based on univariate logistic regression analyses (p < 0.05). With the modifications of these parameters for the in-bore biopsy group, V1 modification of the Briganti 2019 nomogram provided 100% sensitivity and 31.5% specificity (AUC:0.627), while V2 modification provided 75% sensitivity and 46.3% specificity (AUC:0.645)., Conclusions: Briganti 2019 nomogram may be modified by utilizing tumor size/core size (%) for targeted biopsy cores instead of positive core percentage on systematic biopsy or by not taking both parameters into consideration to detect node metastasis risk of patients diagnosed with in-bore biopsies., (© 2024 The Japanese Urological Association.)

Abstract

Introduction: Our aim was to examine the incidence and risk factors of postoperative ileus among patients who underwent robot-assisted radical prostatectomy (RARP)., Material and Methods: We retrospectively reviewed 239 patients who underwent RARP transperitoneally between February 2009 and December 2011. Patients switched to open surgery were excluded. We defined postoperative ileus as intolerance of a solid diet continued until the third postoperative day and beyond. By Clavien classification, we evaluated the perioperative complications that cause or contribute to postoperative ileus. Similarly, we analyzed the impact of anesthesia risk score on the incidence of postoperative ileus., Results: The study included 228 patients. The mean period to tolerate solid food was 1.24 days. Only 6 patients experienced postoperative ileus, all of whom were treated with a conservative approach. The two groups differed significantly in the duration of abdominal drainage, hospital stay, modified Clavien classification, and the presence of comorbidity diabetes mellitus (P <0.5 for all factors). Multiple logistic regression analysis revealed that diabetes mellitus was an independent risk factor for postoperative ileus., Conclusions: We suggest that diabetes mellitus is an independent risk factor for postoperative ileus in patients undergoing robot-assisted radical prostatectomy.
