To describe the infectious and non-infectious complications in men undergoing Inflatable penile prosthesis (IPP) revision with partial and complete component exchange for mechanical malfunction.
We ...performed a multicenter retrospective cohort study of patients who underwent IPP revision. Men undergoing procedures for implant infection were excluded. Patients were divided into those who had complete exchange of the entire device or partial exchange of only one or 2 components. Infectious and non-infectious complications were compared between groups.
Three hundred sixty-eight men had complete exchange of the entire device and 85 had partial component exchange. Men undergoing partial exchange had a significantly higher infection rate (7.1% vs 2.2%, P = .031). The partial exchange group also was more likely to receive antifungals (51.8 vs 16.6%, P < .001), have a modified salvage washout (77.4 vs 60.2%, P = .004), and less likely to receive vancomycin and gentamicin (63.5 vs 83.7%, P < .001). Time to revision was significantly shorter in the partial exchange group (44.9 vs 168.2 months, P < .001). Mean follow-up was slightly longer in the complete exchange group (18.3 vs 13.0 months). In multivariable analysis, partial exchange surgery, vancomycin and gentamicin prophylaxis, modified salvage washout, and antifungal prophylaxis were no longer associated with postoperative infections. The partial exchange group had greater rates of non-infectious complications (21.2% vs 9.5%, P = .005) such as pump malfunction and tubing breakage.
Patients undergoing partial component revision had more infectious and non-infectious complications. These findings suggest that partial component exchange increases complications in men undergoing IPP revision.
To evaluate predictors of implant length for men undergoing primary IPP placement.
A multicenter, retrospective cohort study was performed for men undergoing primary IPP placement at 16 high-volume ...surgical centers. Patient demographics, comorbidities, operative approach, and implanted cylinder and rear tip extender length were recorded. Associations between potential preoperative and intraoperative predictors of total device length were tested using non-parametric correlation and Kruskal-Wallis tests, followed by multiple regression.
Of 3,951 men undergoing primary IPP placement from July 2016 – July 2021, the median implant length was 20 cm (IQR: 19 – 22). Shorter implant length was associated with increasing age in years (β = -0.01, p=0.009), Asian ethnicity (β = -2.34, p=0.008), history of radical prostatectomy (β = -0.35, p=0.001), and use of an infrapubic surgical approach (β = -1.02, p<0.001). Black or African American ethnicity was associated with the implantation of longer devices (β = 0.35, p<0.001). No significant associations were recorded with BMI, history of intracavernosal injections, diabetes mellitus, tobacco use, radiation therapy, Peyronie’s disease, priapism, or cavernosal dilation technique.
The length of an implanted penile prosthesis was found to be associated with preoperative and intraoperative factors including history of radical prostatectomy and operative approach. The knowledge of these associations may assist in the preoperative counseling of patients receiving IPP and help create accurate postoperative expectations.
To assess the difference in outcomes between single dilation (SingD) and sequential dilation (SeqD) in primary penile implantation, hypothesizing that patients who undergo SeqD had higher rates of ...noninfectious complications.
We performed a multicenter, retrospective study of men undergoing primary inflatable penile prosthesis placement. Intraoperative complications and postoperative noninfectious outcomes were assessed between the two groups. Multivariable analysis was performed to identify predictors of complications.
A total of 3293 patients met inclusion criteria. After matching, there were 379 patients who underwent SingD and 379 patients who underwent SeqD. There was no significant difference in intraoperative complications between patients who underwent SingD vs SeqD, nor was there any difference in cylinder length (20 cm with interquartile range IQR 18-21 cm vs 20 cm with IQR 18-20 cm respectively, P = .4). On multivariable analysis, SeqD (OR 5.23 with IQR 2.74-10, P < .001) and older age (OR 1.04 with IQR 1.01-1.06, P = .007) were predictive of postoperative noninfectious complications. There was no significant difference in intraoperative complications between patients who underwent SingD vs SeqD, nor was there any difference in cylinder length. SeqD and older age were predictive of postoperative noninfectious complications.
During inflatable penile prosthesis placement in the uncomplicated patient without fibrosis, SingD is a safe technique to utilize during implantation that will minimize postoperative adverse events, and promote device longevity without loss of cylinder length.
Corporal fibrosis is known to result from prolonged priapism; however, the impact of the timing of penile prosthesis placement after priapism on complication rates is poorly understood.
We sought to ...evaluate the impact of timing of inflatable penile prosthesis (IPP) placement on complications in men with a history of ischemic priapism.
We performed a multicenter, retrospective cohort study of patients with a history of priapism undergoing IPP placement by 10 experienced implantation surgeons. We defined early placement as ≤6 months from priapism to IPP. We identified a 1:1 propensity-matched group of men without a history of priapism and compared complication rates between men who had early placement, late placement, and no history of priapism.
Our primary outcome was postoperative noninfectious complications, and secondary outcomes included intraoperative complications and postoperative infection.
A total of 124 men were included in the study with a mean age of 50.3 ± 12.7 years. A total of 62 had a history of priapism and 62 were matched control subjects. The median duration of priapism was 37 (range, 3-168) hours and the median time from ischemic priapism to IPP placement was 15 months (range, 3 days to 23 years). Fifteen (24%) men underwent early (≤6 months) IPP placement at a median time of 2 months (range, 3 days to 6 months) following the ischemic priapism event. The remaining 47 (76%) underwent placement >6 months following priapism at a median time of 31.5 months (range, 7 months to 23 years). The complication rate in the delayed placement group was 40.5% compared with 0% in the early placement group and control group. Cylinder-related complications such as migration or leak accounted for 8 (57%) of 14 of the postoperative noninfectious complications. Full-sized cylinders were used in all patients who had a cylinder related complication.
Priapism patients should be referred to prosthetic experts early to decrease complication rates in those needing an IPP.
This is a multicenter study from experienced prosthetic urologists but is limited by the retrospective nature and small number of patients in the early placement group.
IPP complication rates are high in men with a history of ischemic priapism, especially when implantation is delayed beyond 6 months.
Variations in climate have been associated with a greater risk of surgical site infections, urinary tract infections, and changes in the skin microbiome; however, limited data exist on the impact of ...climate on inflatable penile prosthesis (IPP) infections.
We sought to evaluate the impact of climate on the risk of IPP infections in a large international, multicenter cohort.
We performed a multi-institutional, retrospective study of patients undergoing IPP surgery. We then evaluated whether the month or season, during which surgery was performed, affected device infections. Implant infections were defined as infections requiring device explantation. A univariate logistic regression analysis was undertaken.
Our primary outcome was implant infection.
A total of 5289 patients with a mean age of 62.2 ± 10.8 years received IPP placement. There was a fairly even distribution of implants performed in each season. A total of 103 (1.9%) infections were recorded. There were 32 (31.1%) IPP infections in patients who underwent surgery in the summer, followed by 28 (27.2%) in the winter, 26 (25.2%) in the spring, and 17 (16.5%) in the fall. No statistically significant differences were recorded in terms of season (P = .19) and month (P = .29). The mean daily temperature (P = .43), dew point (P = .43), and humidity (P = .92) at the time of IPP placement was not associated with infection.
These findings provide reassurance to prosthetic urologists that infection reduction strategies do not need to be tailored to local climate.
Climate data were not directly recorded for each hospital, but rather based on the monthly averages in the city where the surgery was performed.
The climate at time of IPP placement and time of year of surgery is not associated with IPP infection risk.
Microdenervation of the spermatic cord (MSCD) is an effective treatment modality for men with intractable scrotal content pain. For patients not interested in preserving fertility, some centers ...advocate ligation of the vas during denervation, while others prefer stripping of the vas deferens to preserve the vasal artery, hence preserving vasculature to the testis and possibly decreasing post-operative congestion pain.
To compare outcomes of patients with chronic orchialgia, who underwent MSCD by either stripping or ligating the vas deferens.
A retrospective chart review of 85 patients who underwent MSCD from 2017-2023 was performed. Patients' demographics including history of prior surgical procedures were recorded. Response to surgery was evaluated as either complete resolution of pain, partial resolution of pain, or no improvement in pain.
Eighty-five patients underwent MSCD with a median (interquartile range, IQR) age of 36 (25.5-46.5) years and median duration of pain of 16 (6-31) months. Thirty-seven patients underwent stripping of vas, while 48 underwent ligation of vas during MSCD. Median follow up was 12 months. Twenty-one (43.5%) patients had prior inguinal scrotal surgery in the ligation group compared to 5 (13.5%) in the stripping group, p = 0.003. The etiology of pain was similar between the groups. The response to MSCD between the two groups was similar, 67.6% of patients who underwent stripping had complete resolution of pain versus 66.7% of those who had ligation (p = 0.968), with similar rates of post-operative complications (p-value = 0.132).
In men with intractable chronic scrotal content pain with no interest in preserving fertility, ligation, or stripping of the vas deferens yields similar outcomes with regard to pain resolution. Both techniques are safe with no reports of any testicular atrophy.
The efficacy, safety, and postoperative outcomes of synchronous surgery for concomitant erectile dysfunction (ED) and stress urinary incontinence (SUI) remain unclear.
We performed a systematic ...review and meta-analysis to evaluate the available synchronous surgical approaches for concomitant ED and SUI and to assess the reoperation rates compared to asynchronous surgery and surgery only for ED or SUI.
We searched PubMed, Cochrane Library, and Embase databases until June 2022 for relevant studies. Based on data availability, we performed a meta-analysis of odds ratios (ORs) comparing reoperation rates after synchronous surgery in patients with concomitant ED and SUI versus asynchronous surgery, as well as surgery solely for ED or SUI (PROSPERO: CRD42022326941).
We included 18 studies in the systematic review (16,517 patients) and 5 in the meta-analysis. Comparing synchronous implantation of penile prosthesis and artificial urinary sphincter (AUS) versus asynchronous surgery, no statistically significant differences were observed in the reoperation rates OR:0.98, 95% confidence interval (CI): 0.52-1.84, I2:0%). Comparing synchronous implantation of both penile prosthesis and AUS versus implantation of only a penile prosthesis or an AUS, combined surgery was associated with higher reoperation rates (OR:2.02, 95%CI: 1.29-3.16, I2:36% and OR:1.7, 95%CI: 1.25-2.32, I2:0%, respectively). Synchronous surgery led to high satisfaction rates and significant improvement in ED and SUI. Evidence for the combination of penile prosthesis with a male sling or the ProACT device is low, but data suggests it may be safe and effective. The synchronous placement of a Mini-Jupette sling and penile prosthesis represents a promising treatment modality for the correction of ED and mild SUI and/or climacturia.
Synchronous penile prosthesis and AUS implantation appears safe and effective in patients with severe ED and SUI. Further high-quality studies are mandatory to strengthen the current scarce evidence for synchronous surgery in patients with ED and SUI.
Several institutions have reported their experience with outpatient robot-assisted radical prostatectomy (O-RARP). However, it is unclear if the utilization of this approach represents an improvement ...over inpatient robot-assisted radical prostatectomy (I-RARP). This meta-analysis sought to compare the surgical outcomes between O-RARP and I-RARP.
For relevant articles, three electronic databases, including PubMed, Scopus, and Web of Science, were searched from their inception until April 30, 2022. A meta-analysis has been reported in line with PRISMA 2020 and AMSTAR guidelines. The risk ratio (RR) and weighted mean difference (MD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CI).
of the 297 retrieved abstracts, 12 underwent full-text review, and 11 studies were included in the final analysis, comprising a total cohort of 2,875 cases of robot-assisted radical prostatectomy (892 O-RARP cases and 1,983 I-RARP cases). Compared to I-RARP, the O-RARP group had lower mean operative time (MD = −9.4 minutes, 95% CI −15.1 to −3.7, P = 0.001), fewer overall postoperative complications (RR = 0.65, 95% CI 0.46 to 0.92, P = 0.017), shorter hospital stay (MD = −22.9 hours, 95% CI −26.0 to −19.7, P ≤ 0.001), and lower postoperative opioid requirements (RR = 0.45, 95% CI 0.28 to 0.71, P = 0.001). There were no significant differences in other outcomes, including: estimated blood loss, postoperative pain score, unscheduled visits after surgery, positive surgical margins, biochemical recurrence, International Prostate Symptom Score (IPSS) after surgery, or three- and six-month continence rates.
This meta-analysis demonstrates that O-RARP is a safe and feasible option for patients undergoing surgery for localized prostate cancer. Further studies are needed to better evaluate optimal patient selection, associated healthcare costs, and patient-reported outcomes.
