RESUMEN

BACKGROUND: In addition to erectile dysfunction, urinary incontinence is the most common functional limitation after radical prostatectomy (RPE) for prostate cancer (PCa). The German S3 guideline recommends informing patients about possible effects of the therapy options, including incontinence. However, only little data on continence from routine care in German-speaking countries after RPE are currently available, which makes it difficult to inform patients. OBJECTIVE: The aim of this work is to present data on the frequency and severity of urinary incontinence after RPE from routine care. MATERIALS AND METHODS: Information from the PCO (Prostate Cancer Outcomes) study is used, which was collected between 2016 and 2022 in 125 German Cancer Society (DKG)-certified prostate cancer centers in 17,149 patients using the Expanded Prostate Cancer Index Composite Short Form (EPIC-26). Changes in the "incontinence" score before (T0) and 12 months after RPE (T1) and the proportion of patients who used pads, stratified by age and risk group, are reported. RESULTS: The average score for urinary incontinence (value range: 0-worst possible to 100-best possible) was 93 points at T0 and 73 points 12 months later. At T0, 97% of the patients did not use a pad, compared to 56% at T1. 43% of the patients who did not use a pad before surgery used at least one pad a day 12 months later, while 13% use two or more. The proportion of patients using pads differs by age and risk classification. CONCLUSION: The results provide a comprehensive insight into functional outcome 12 months after RPE and can be taken into account when informing patients.

RESUMEN

Background: Robot-assisted repair of benign ureteroenteric anastomotic strictures (UAS) provides an alternative to the open approach. We aimed to report short-, medium-, and long-term outcomes for robotic repair of benign UAS, and to provide a detailed video demonstration of critical operative techniques in performing this procedure robotically. Materials and Methods: Between January 2013 and September 2022, 31 patients from seven institutions who previously underwent radical cystectomy and subsequently developed UAS underwent robotic repair of UAS. Perioperative variables were prospectively collected, and postoperative outcomes were assessed. The surgery starts with a lysis of adhesions after previous surgery. Ureters are dissected, and the level of the stricture is identified. The ureter is then divided, and the stricture is resected. Finally, the ureter is spatulated and reimplanted with Nesbit technique after stenting with Double-J stents. In cases where both ureters show strictures, Wallace technique for reimplantation can be applied. Results: After robotic or open cystectomy, 31 patients had a total of 43 UAS at a median (interquartile range) follow-up of 21 (9-43) months. Median stricture length was 2.0 (1.0-3.25) cm, operative duration was 141 (121-232) minutes, estimated blood loss was 100 (50-150) mL, and length of hospital stay was 5 (3-9) days. One (3.2%) case was converted to open and one (3.2%) intraoperative complication occurred. Seven (22.6%) patients experienced postoperative complications, including four (12.9%) Clavien-Dindo grade 3 complications. No Clavien-Dindo grade 4 or 5 complications occurred. Stricture recurrence occurred in 2 (6.5%) patients. Conclusions: These results demonstrate that robotic repair of UAS is feasible and effective approach with outcomes in line with prior open series. Patient Consent Statement: Authors have received and archived patient consent for video recording and publication in advance of video recording of procedure.

RESUMEN

BACKGROUND: Little is known regarding functional outcomes after robot-assisted radical cystectomy (RARC) and intracorporeal neobladder (ICNB) reconstruction. OBJECTIVE: To report on urinary continence (UC) and erectile function (EF) at 12 mo after RARC and ICNB reconstruction and investigate predictors of these outcomes. DESIGN, SETTING, AND PARTICIPANTS: We used data from a multi-institutional database of patients who underwent RARC and ICNB reconstruction for bladder cancer. SURGICAL PROCEDURE: The cystoprostatectomy sensu stricto followed the conventional steps. ICNB reconstruction was performed at the physician's discretion according to the Studer/Wiklund, S pouch, Gaston, vescica ileale Padovana, or Hautmann technique. The techniques are detailed in the video accompanying the article. MEASUREMENTS: The outcomes measured were UC and EF at 12 mo. RESULTS AND LIMITATIONS: A total of 732 male patients were identified with a median age at diagnosis of 64 yr (interquartile range 58-70). The ICNB reconstruction technique was Studer/Wiklund in 74%, S pouch in 1.5%, Gaston in 19%, vescica ileale Padovana in 1.5%, and Hautmann in 4% of cases. The 12-mo UC rate was 86% for daytime and 66% for nighttime continence, including patients who reported the use of a safety pad (20% and 32%, respectively). The 12-mo EF rate was 55%, including men who reported potency with the aid of phosphodiesterase type 5 inhibitors (24%). After adjusting for potential confounders, neobladder type was not associated with UC. Unilateral nerve-sparing (odds ratio [OR] 3.85, 95% confidence interval [CI] 1.88-7.85; p < 0.001) and bilateral nerve-sparing (OR 6.25, 95% CI 3.55-11.0; p < 0.001), were positively associated with EF, whereas age (OR 0.93, 95% CI 0.91-0.95; p < 0.001) and an American Society of Anesthesiologists score of 3 (OR 0.46, 95% CI 0.25-0.89; p < 0.02) were inversely associated with EF. CONCLUSIONS: RARC and ICNB reconstruction are generally associated with good functional outcomes in terms of UC. EF is highly affected by the degree of nerve preservation, age, and comorbidities. PATIENT SUMMARY: We investigated functional outcomes after robot-assisted removal of the bladder in terms of urinary continence and erectile function. We found that, in general, patients have relatively good functional outcomes at 12 months after surgery.

RESUMEN

BACKGROUND: Robotic surgery has gained popularity for the reconstruction of pelvic floor defects. Nonetheless, there is no evidence that robot-assisted reconstructive surgery is either appropriate or superior to standard laparoscopy for the performance of pelvic floor reconstructive procedures or that it is sustainable. The aim of this project was to address the proper role of robotic pelvic floor reconstructive procedures using expert opinion. METHODS: We set up an international, multidisciplinary group of 26 experts to participate in a Delphi process on robotics as applied to pelvic floor reconstructive surgery. The group comprised urogynecologists, urologists, and colorectal surgeons with long-term experience in the performance of pelvic floor reconstructive procedures and with the use of the robot, who were identified primarily based on peer-reviewed publications. Two rounds of the Delphi process were conducted. The first included 63 statements pertaining to surgeons' characteristics, general questions, indications, surgical technique, and future-oriented questions. A second round including 20 statements was used to reassess those statements where borderline agreement was obtained during the first round. The final step consisted of a face-to-face meeting with all participants to present and discuss the results of the analysis. RESULTS: The 26 experts agreed that robotics is a suitable indication for pelvic floor reconstructive surgery because of the significant technical advantages that it confers relative to standard laparoscopy. Experts considered these advantages particularly important for the execution of complex reconstructive procedures, although the benefits can be found also during less challenging cases. The experts considered the robot safe and effective for pelvic floor reconstruction and generally thought that the additional costs are offset by the increased surgical efficacy. CONCLUSION: Robotics is a suitable choice for pelvic reconstruction, but this Delphi initiative calls for more research to objectively assess the specific settings where robotic surgery would provide the most benefit.

RESUMEN

OBJECTIVES: Nephron-sparing surgery (NSS) exposes the kidney to ischemia-reperfusion injury. Blood loss and hypotension are also associated with kidney injury. We aimed to test the hypothesis that, during NSS, both ischemia duration and blood loss significantly affect postoperative renal function and that their effects interact. METHODS: Consecutive patients undergoing NSS were enrolled. The primary endpoint was renal function expressed as the absolute delta between preoperative and postoperative peak creatinine. We developed a generalized linear model with the ischemia duration and absolute hemoglobin difference as independent variables, their interaction term, and the RENAL score. The model was than expanded to include a history of hypertension (as a proxy for hypotension susceptibility) and related interaction terms. Further, we described the perioperative and mid-term oncological outcomes. RESULTS: A total of 478 patients underwent NSS, and 209 (43.7%) required ischemia for a mean of 10.9 min (SD 8). Both the ischemia duration (partial eta 0.842, p = 0.006) and hemoglobin difference (partial eta 0.933, p = 0.029) significantly affected postoperative renal function, albeit without evidence of a significant interaction (p = 0.525). The RENAL score also significantly influenced postoperative renal function (p = 0.023). After the addition of a previous history of hypertension, the effects persisted, with a significant interaction between blood loss and a history of hypertension (p = 0.02). CONCLUSIONS: Ischemia duration and blood loss had a similar impact on postoperative renal function, albeit without potentiating each other. While the surgical technique and ischemia minimization remain crucial to postoperative kidney function, increased awareness of conscious hemodynamic management appears warranted.

RESUMEN

INTRODUCTION: Since the beginning of the pandemic in 2020, COVID-19 has changed the medical landscape. International recommendations for localized prostate cancer (PCa) include deferred treatment and adjusted therapeutic routines. MATERIALS AND METHODS: To longitudinally evaluate changes in PCa treatment strategies in urological and radiotherapy departments in Germany, a link to a survey was sent to 134 institutions covering two representative baseline weeks prior to the pandemic and 13 weeks from March 2020 to February 2021. The questionnaire captured the numbers of radical prostatectomies, prostate biopsies and case numbers for conventional and hypofractionation radiotherapy. The results were evaluated using descriptive analyses. RESULTS: A total of 35% of the questionnaires were completed. PCa therapy increased by 6% in 2020 compared to 2019. At baseline, a total of 69 radiotherapy series and 164 radical prostatectomies (RPs) were documented. The decrease to 60% during the first wave of COVID-19 particularly affected low-risk PCa. The recovery throughout the summer months was followed by a renewed reduction to 58% at the end of 2020. After a gradual decline to 61% until July 2020, the number of prostate biopsies remained stable (89% to 98%) during the second wave. The use of RP fluctuated after an initial decrease without apparent prioritization of risk groups. Conventional fractionation was used in 66% of patients, followed by moderate hypofractionation (30%) and ultrahypofractionation (4%). One limitation was a potential selection bias of the selected weeks and the low response rate. CONCLUSION: While the diagnosis and therapy of PCa were affected in both waves of the pandemic, the interim increase between the peaks led to a higher total number of patients in 2020 than in 2019. Recommendations regarding prioritization and fractionation routines were implemented heterogeneously, leaving unexplored potential for future pandemic challenges.

RESUMEN

INTRODUCTION: The aim of the study is to compare length of hospital stay, transfusion rates, and re-intervention rates during hospitalization for transurethral resection of the prostate (TUR-P), open prostatectomy (OP), and laser therapy (LT) for surgical treatment of benign prostatic obstruction (BPO). METHODS: URO-Cert is an organization, in which clinical data of prostatic diseases from 2 university, 19 public, and 3 private hospitals and 270 office-based urologists are collected in order to document treatment quality. Data on diagnostics, therapy, and course of disease are recorded web based. The analysis includes datasets from 2005 to 2017. RESULTS: Of 10,420 patients, 8,389 were treated with TUR-P, 1,334 with OP, and 697 with LT. Median length of hospital stay was 6 days (IQR: 4-7) for TUR-P, 9 days (IQR: 7-11) for OP, and 5 days (IQR: 4-6) for LT (p < 0.001). Risk for a hospital stay ≥7 days was higher for OP versus TUR-P (OR: 7.25; 95% CI = 6.27-8.36; p < 0.001) and LT (OR: 17.89; 95% CI = 14.12-22.65; p < 0.001) and higher for TUR-P versus LT (OR: 2.47; 95% CI = 2.03-3.01; p < 0.001). OP had a significantly higher risk for transfusions than TUR-P (OR: 2.44; 95% CI = 1.74-3.41; p < 0.001) and LT (OR: 3.32; 95% CI = 1.56-7.01; p < 0.001). Transfusion rates were not significantly different between TUR-P and LT (OR: 1.36; 95% CI = 0.66-2.79; p = 0.51). Risk of re-intervention was not different between all 3 approaches. CONCLUSION: OP was associated with higher transfusion rates and longer hospital stay than TUR-P and LT. Risk of transfusion was not different between TUR-P and LT, but TUR-P was inferior to LT concerning length of hospital stay. Re-intervention rates during hospitalization did not differ between the groups.

RESUMEN

BACKGROUND: Simultaneous urothelial cancer manifestation in the lower and upper urinary tract affects approximately 2% of patients. Data on the surgical benchmarks and mid-term oncological outcomes of enbloc robot-assisted radical cystectomy and nephro-ureterectomy are scarce. METHODS: After written informed consent was obtained, we prospectively enrolled consecutive patients undergoing enbloc radical cystectomy and nephro-ureterectomy with robotic assistance from the DaVinci Si-HD® system in a prospective institutional database and collected surgical benchmarks and oncological outcomes. Furthermore, as one console surgeon conducted all the procedures, whereas the team providing bedside assistance was composed ad hoc, we assessed the impact of this approach on the operative duration. RESULTS: Nineteen patients (9 women), with a mean age of 73 (SD: 7.5) years, underwent simultaneous enbloc robot-assisted radical cystectomy and nephro-ureterectomy. There were no cases of conversion to open surgery. In the postoperative period, we registered 2 Clavien-Dindo class 2 complications (transfusions) and 1 Clavien-Dindo class 3b complication (port hernia). After a median follow-up of 23 months, there were 3 cases of mortality and 1 case of metachronous urothelial cancer (contralateral kidney).The total operative duration did not decrease with increasing experience (r = 0.174, p = 0.534). In contrast, there was a significant, inverse, strong correlation between the console time relative to the total operative duration and the number of conducted procedures after adjusting for the degree of adhesions and the type of urinary diversion(r = -0.593, p = 0.02). CONCLUSIONS: These data suggest that en bloc simultaneous robot-assisted radical cystectomy and nephro-ureterectomy can be safely conducted with satisfactory mid-term oncological outcomes. With increasing experience, improved performance was detectable for the console surgeon but not in terms of the total operative duration. Simulation training of all team members for highly complex procedures might be a suitable approach for improving team performance. TRIAL REGISTRATION: Not applicable. Video Abstract.

RESUMEN

INTRODUCTION: After the outbreak of COVID-19 unprecedented changes in the healthcare systems worldwide were necessary resulting in a reduction of urological capacities with postponements of consultations and surgeries. MATERIAL AND METHODS: An email was sent to 66 urological hospitals with focus on robotic surgery (RS) including a link to a questionnaire (e.g. bed/staff capacity, surgical caseload, protection measures during RS) that covered three time points: a representative baseline week prior to COVID-19, the week of March 16th-22nd and April 20th-26th 2020. The results were evaluated using descriptive analyses. RESULTS: 27 out of 66 questionnaires were analyzed (response rate: 41%). We found a decrease of 11% in hospital beds and 25% in OR capacity with equal reductions for endourological, open and robotic procedures. Primary surgical treatment of urolithiasis and benign prostate syndrome (BPS) but also of testicular and penile cancer dropped by at least 50% while the decrease of surgeries for prostate, renal and urothelial cancer (TUR-B and cystectomies) ranged from 15 to 37%. The use of personal protection equipment (PPE), screening of staff and patients and protection during RS was unevenly distributed in the different centers-however, the number of COVID-19 patients and urologists did not reach double digits. CONCLUSION: The German urological landscape has changed since the outbreak of COVID-19 with a significant shift of high priority surgeries but also continuation of elective surgical treatments. While screening and staff protection is employed heterogeneously, the number of infected German urologists stays low.

RESUMEN

BACKGROUND: The cost-effectiveness of robot-assisted partial nephrectomy (RAPN) vs. the open procedure is not established. METHODS: We estimated in-hospital complications and the cost of RAPN vs. open partial nephrectomy (OPN) using an economic model. Costs incurred both intraoperatively and in hospital were considered. US data were extracted from existing literature. RESULTS: Mean in-hospital costs were $14,824 (95% CI $13,368-$16,898) for RAPN and $15,094 (95% CI $13,491-$17,140) for OPN. Complications after RAPN occurred in 23.3% (95% CI 20.0-25.8%) and after OPN in 36.1% (95% CI 35.6-36.6%) of the patients. In a sensitivity analysis, limited centre experience was associated with relevant increase in RAPN cost and consequently in low cost-effectiveness. CONCLUSIONS: In this economic model based on US data, RAPN resulted in nominally lower cost but fewer perioperative complications than OPN. RAPN was not cost-effective in less experienced centres.

RESUMEN

AIMS: To investigate the association of bladder cold sensation (BCS) during the ice water test (IWT) and pain perception when botulinum toxin injections (BTI) are administered into the bladder wall. MATERIAL AND METHODS: In 86 patients with idiopathic overactive bladder, the BCS during the IWT was investigated. Patients were divided into 2 groups: with and without BCS. During subsequent administration of BTI, the number of perceived and painful injections as well as the pain levels on a 0-100 pain scale were compared in both groups using Student t test. RESULTS: Thirty-five patients reported a BCS, while 51 did not. After 10 BTI, the mean number of perceived injections was 7.9 in patients with and 2.4 in patients without BCS (p < 0.0001). The mean number of painful injections was 5.4 in patients with BCS and 4.3 in patients without (p < 0.001). Mean levels on a 0-100 pain scale were 33.7 in patients with and 17.8 in patients without cold sensation (p < 0.0001). CONCLUSION: The association of BCS during the IWT and pain to during BTI may implicate that the perceptions of cold and pain in the urinary bladder may use similar receptors and neuronal pathways.

RESUMEN

Purpose This study evaluates the hypothesis that bipolar stimulation of the S3 and S4 sacral roots may enhance the efficacy of the percutaneous nerve evaluation (PNE) test. Material and Methods In this case-control-study, we enrolled 43 patients undergoing bipolar PNE and 57 controls undergoing unipolar PNE. For bipolar PNE, four test electrodes were placed at the bilateral S3 and S4 roots. The electrodes at the S3 and S4 roots of each side were connected to obtain bipolar stimulation. The test protocol over eight days included unilateral and bilateral stimulation of the S3 and S4 sacral roots. Eight days after implantation, the electrodes were removed and test results from bladder diaries were collected. Results The unipolar test procedure was successful in 47 % (27/57) of cases. The bipolar test procedure was successful in 58 % (25/43). In the bipolar group, 63 % (12/19) of patients with neurogenic tract dysfunction profited from treatment, vs. 57 % (13/23) in the unipolar group. Patients without a neurologic disease had a successful test in 58 % (14/24) of cases treated with bipolar PNE vs. 41 % (14/24) treated with unipolar PNE. Multivariate analysis did not reveal a statistically significant difference between groups. Conclusion Although not significant in this population, bipolar PNE may improve efficacy compared to the unipolar test procedure. Similar observations were made in subgroups of neurogenic and non-neurogenic bladder dysfunctions.

RESUMEN

The objectives of this study are to describe the surgical technique for simultaneous en-bloc robot-assisted radical cystectomy and nephro-ureterectomy, to report its surgical bench marks, and finally, to summarize the current evidence on the procedure. After written informed consent, we prospectively enrolled consecutive patients undergoing simultaneous en-bloc robot-assisted radical cystectomy and nephro-ureterectomy in a prospective institutional database. We performed all procedures with robotic assistance from the DaVinci Si-HD®, a four-arm robotic system. Endpoints included surgery duration, estimated intra-operative blood loss, resection margins, intra-, and post-operative complications. Furthermore, we describe oncological outcome at follow-up. We conducted six (54.4 %) right-sided and five (45.5 %) left-sided nephro-ureterectomies. Urinary diversion consisted in nine (81.2 %) ureterocutaneostomies and in two (18.8 %) ileum conduits. The median surgery duration was 287 min [interquartile range (Q1-Q3) 253-328], thereof 196-min console time (Q1-Q3 158-230). The median-estimated blood loss was 235 mL (Q1-Q3 200-262). We did not register any intra-operative complications or conversions to open surgery. Post-operatively, each one patient suffered a Clavien-Dindo grade 1 (paralytic ileus), grade 2 (blood transfusion), and grade 3 complication (port hernia). After a median follow-up of 7 months (Q1-Q3 4-25), we registered one recurrence, a metachronous transitional cell cancer of the contralateral kidney 24 months after the initial procedure. En-bloc robot-assisted radical cystectomy and nephro-ureterectomy was associated with limited procedure duration, minor blood loss and satisfying intra- and post-operative outcomes.

RESUMEN

PURPOSE: To evaluate the cost-effectiveness of robot-assisted partial nephrectomy (RAPN) and secondarily of laparoscopic PN (LPN) compared to the open procedure. METHODS: Model-based cost-effectiveness analysis: The model was structured as decision tree. The model was populated with published data. We measured intraoperative, postoperative complications, and inhospital deaths. We expressed costs in US dollars ($).The reference analysis calculated the mean cost and the mean number of each endpoint over 5000 iterations using a second-order Monte Carlo simulation. We conducted extensive sensitivity analyses. RESULTS: The mean inhospital costs were $13,186 for RAPN, $10,782 for LPN, and $12,539 for open partial nephrectomy (OPN), respectively. The incremental cost to prevent an inhospital event amounted to $5005 for RAPN compared to OPN. Lower RENAL scores were associated with lower incremental cost per avoided complications. Under assumption of 55 % higher costs in patients with complications, RAPN dominated OPN. LPN dominated OPN. We are aware of the following limitations: First, cost data for patients with and without complications were not available and we assumed the median cost for all cases, i.e., the analysis overestimated the cost associated with RAPN; second, we focused on inhospital estimates and did not apply a societal perspective. CONCLUSIONS: RAPN appears to be a cost-effective mean to avoid inhospital complications; however, these results might not apply to low-volume hospitals or to other health care systems.

RESUMEN

INTRODUCTION AND HYPOTHESIS: Robotic assistance simplifies laparoscopic procedures. We hypothesize that robot-assisted sacrocolpopexy is a rapid and safe procedure with satisfying short-term and midterm functional results. METHODS: After informed consent, we enrolled 101 consecutive patients undergoing sacrocolpopexy at Alfried Krupp Hospital, Essen, Germany. After a median follow-up of 22 months, we assessed midterm functional results as the primary endpoint. Secondary endpoints included surgical duration, blood loss, intraoperative complications, and postoperative complications. We described frequencies as counts (percent) and continuous data as median [interquartile range (Q1-Q3)] or mean [standard deviation (SD)], as appropriate. RESULTS: We enrolled 101 patients. The mean age was 69 years (SD 11); 75 women (74.3 %) had undergone previous abdominal surgery. Among the patients, 95 (94.1 %) presented with anterior vaginal wall prolapse Baden-Walker grade 2-3, 74 (73.3 %) vaginal vault prolapse, and 9 (8.9 %) concomitant rectocele. Fifty (50 %) patients underwent a modified Burch procedure in addition to sacrocolpopexy. The median surgical duration was 96 min (Q1-Q3 83-130). There were six (5.9 %) minor intraoperative complications but no conversions to open surgery. Postoperatively, we registered five (4.9 %) Clavien-Dindo grade I complications, three (3.0 %) grade II complications, and one (1.0 %) grade III complication. After a median follow-up of 22 months (Q1-Q3 12-49), the patients reported significant decreased impact of pelvic organ prolapse (POP) on quality of life as well as bother resulting from POP symptoms. The overall success rate, defined as none or minor impact of POP on quality of life, was 75 %. CONCLUSIONS: In this single-surgeon study, robot-assisted sacrocolpopexy was a safe and rapidly performed procedure that achieved good medium-term functional results.

RESUMEN

Until a few years ago, the treatment options for metastatic renal cell cancer (mRCC) were very limited. The growing understanding of the molecular pathomechanisms underlying RCC allowed the development of new treatment approaches. Meanwhile, several approved target-oriented substances from different drug classes are available for mRCC. The mechanism of action of vascular endothelial growth factor (VEGF) and VEGF receptor or mTOR inhibition is well documented by phase III trials and reflected in the current guidelines. However, no predictive biomarkers have been identified in mRCC so far to demonstrate a benefit by a specific compound in an individual patient. Meanwhile, the sequential use of 'targeted therapies' in mRCC has been established as standard treatment. The optimal sequence of available agents is still unclear. A German RCC expert panel discussed and developed an algorithm for the choices of first- and second-line treatment in mRCC based on established clinical criteria.

RESUMEN

OBJECTIVE: To describe the prevalence of incidental prostate cancer in patients undergoing radical cystoprostatectomy for bladder malignancy; to quantify the association between incidental prostate cancer and mortality in these patients; and to quantify the association between incidental prostate cancer and age in radical cystoprostatectomy specimens. METHODS: Consecutive patients undergoing radical cystoprostatectomy for bladder malignancy at six academic institutions were assessed. End-points were the histological diagnosis of prostate cancer in the radical cystoprostatectomy specimens and mortality. The association between incidental prostate cancer and mortality was calculated by multivariable Cox regression, and the association between age and the occurrence of prostate cancer was calculated by logistic regression. RESULTS: A total of 1122 patients (aged 65.6 ± 10 years) were included in this analysis. Prostate cancer was detected in 17.8% (n = 200) of the cystoprostatectomy specimens. After multivariable adjustment, prostate cancer was significantly associated with mortality (hazard ratio 1.27, 95% confidence interval 1.03-1.56). There was a significant association between age and the presence of prostate cancer in the cystoprostatectomy specimen. The odds ratio for the presence of prostate cancer was 1.028 (95% confidence interval 1.011-1.045; P < 0.001) per each year after the age of 40 years. CONCLUSIONS: Concomitant prostate cancer is an independent prognostic factor for mortality after radical cystoprostatectomy for bladder cancer. When considering a prostate-sparing technique, urologists should consider that every fifth to sixth patient will present with a concomitant prostate cancer, and that after the age of 40 years, the odds of a concomitant prostate cancer increases by 2.8% per year, thus warranting a careful balance between the oncological risks and quality of life issues.

RESUMEN

PURPOSE: To test the hypothesis that age affects functional results after 80W photoselective vaporization of the prostate (PVP). PATIENTS AND METHODS: In 156 patients who were undergoing PVP for benign prostatic hyperplasia (BPH), we assessed the International Prostate Symptom Score (IPSS) and Quality of Life (QoL) score preoperatively and at 12 months. We calculated the association between age and IPSS and QoL results and corrected it for prostate-specific antigen (PSA) value, whose impact on PVP functional results is well accepted. RESULTS: Median patient age was 66 years (interquartile range [IQR] 62-75), median preoperative IPSS 20.5 (IQR 15-25) and QoL 4 (IQR 3-5). At 12 months, the median IPSS percent decrease was 58.8% (range 33%-75%), and the median QoL percent decrease was 66.7% (range 25%-80%). Age was independently associated with both (P < 0.05). In contrast, after adjustment for age, PSA was not significantly associated with percent IPSS decrease (P = 0.561), and its association with QoL was at the limit of significance (P = 0.05). CONCLUSIONS: Age independently and strongly affects IPSS and QoL results at 12 months after 80W PVP.
