Penile rehabilitation after pelvic cancer surgery.

ABSTRACT: Erectile dysfunction is the most common complication after pelvic radical surgery. Rehabilitation programs are increasingly being used in clinical practice but there is no high level of evidence supporting its efficacy. The principle of early penile rehabilitation stems from animal studies showing early histological and molecular changes associated with penile corporal hypoxia after cavernous nerve injury. The concept of early penile rehabilitation was developed in late nineties with a subsequent number of clinical studies supporting early pharmacologic penile rehabilitation. These studies included all available phosphodiesterase type 5 inhibitors, intracavernosal injection and intraurethral use of prostaglandin E1 and to lesser extent vacuum erectile devices. However, these studies are of small number, difficult to interpret, and often with no control group. Furthermore, no studies have proven an in vivo derangement of endothelial or smooth muscle cell metabolism secondary to a prolonged flaccid state. The purpose of the present report is a synthetic overview of the literature in order to analyze the concept and the rationale of rehabilitation program of erectile dysfunction following radical pelvic surgery and the evidence of such programs in clinical practice. Emphasis will be placed on penile rehabilitation programs after radical cystoprostatectomy, radical prostatectomy, and rectal cancer treatment. Future perspectives are also analyzed.

Project description:ObjectiveTo investigate the rate of erectile dysfunction (ED) after pelvic ring fracture (PRF).DesignSystematic review and meta-analysis.MethodsA systematic literature search of the Cochrane, EMBASE, MEDLINE, Scopus and Web of Science Library databases was conducted in January 2020. Included were original studies performed on humans assessing ED after PRF according to the 5-item International Index of Erectile Function (IIEF-5) questionnaire and fracture classification following Young and Burgess, Tile or Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association. Furthermore, interventional cohort studies assessing the effect of penile rehabilitation therapy with phosphodiesterase-5-inhibitors (PDE-5-I) on IIEF-5 scores compared before and after treatment were included. Results were presented as forest plots of proportions of patients with ED after PRF or mean changes on IIEF-5 questionnaires before and after penile rehabilitation. Studies not included in the quantitative analysis were narratively summarised. Risk of bias assessment was conducted using the revised tool for the Quality Assessment on Diagnostic Accuracy Studies.ResultsThe systematic literature search retrieved 617 articles. Seven articles were included in the qualitative analysis and the meta-analysis. Pooled proportions revealed 37% of patients with ED after suffering any form of PRF (result on probability scale pr=0.37, 95% CI: 0.26 to 0.50). Patients after 3 months of penile rehabilitation therapy reported a higher IIEF-5 score than before (change score=6.5 points, 95% CI: 2.54 to 10.46, p value=0.0013).ConclusionDespite some heterogeneity and limited high-quality research, this study concludes that patients suffering from any type of PRF have an increased risk of developing ED. Oral intake of PDE-5-I for the purpose of penile rehabilitation therapy increases IIEF-5 scores and may relevantly influence quality-of-life in these patients.Prospero registration numberCRD42020169699.

Project description:BackgroundPenile cancer (PeCa) is rare, and the survival of patients with advanced disease remains poor. A better understanding of where treatment fails could aid the development of new treatment strategies.ObjectiveTo describe the disease course after pelvic lymph node (LN) treatment for PeCa.Design setting and participantsWe retrospectively analysed 228 patients who underwent pelvic LN treatment with curative intent from 1969 to 2016. The main treatment modalities were neoadjuvant chemotherapy, chemoradiation, and pelvic LN dissection.Outcome measurements and statistical analysisIn the case of multiple recurrence locations, the most distant location was taken and recorded as follows: local (penis), regional (inguinal and pelvic LN), and distant (any other location). A competing risk analysis was used to calculate the time to recurrence per location, and a Kaplan-Meier analysis was used for overall survival (OS).Results and limitationsThe median follow-up of the surviving patients was 79 mo. The reason for pelvic treatment was pelvic involvement on imaging (29%), two or more tumour-positive inguinal LNs (61%), or inguinal extranodal extension (52%). More than half of the patients (61%) developed a recurrence. The median recurrence-free survival was 11 mo. The distribution was local in 9%, regional in 27%, and distant in 64% of patients. The infield control rate of nonsystemically treated patients was 61% (113/184). From the start of pelvic treatment, the median OS was 17 mo (95% confidence interval 12-22). After regional or distant recurrence, all but one patient died of PeCa with median OS after a recurrence of 4.4 (regional) and 3.1 (distant) mo. This study is limited by its retrospective nature.ConclusionsThe prognosis of PeCa patients treated on their pelvis who recur despite locoregional treatment is poor. The tendency for systemic spread emphasises the need for more effective systemic treatment strategies.Patient summaryIn this report, we looked at the outcomes of penile cancer patients in an expert centre undergoing various treatments on their pelvis. We found that survival is poor after recurrence despite locoregional treatment. Therefore, better systemic treatments are necessary.

Project description:Patients complaining of short penile length pose a challenge in urology practice. Those men who present seeking penile lengthening surgery usually overestimate 'normal' penile length, and may in often cases relate their penile length with the degree of masculinity and self-esteem. Penile prosthetic devices are the gold standard treatment of erectile dysfunction (ED) after failure of conservative options. Penile shortening is the most prevalent long-term complaint after successful inflatable penile prosthesis (IPP) placement. This has a significant impact on patient's overall satisfaction and quality of life. Using PubMed, we performed a thorough literature review of the current procedures of preservation or enhancement of penile length as well as reported perioperative protocols in patients undergoing penile prosthesis (PP) insertion. Keywords used were "penile lengthening", "penile enhancement", "penile girth", "inflatable penile prosthesis" and "glans augmentation". Several surgical techniques can be offered in the setting of penile shortening concurrently with PP insertion, e.g., sub-coronal approach of PP placement, sliding technique, modified sliding technique (MoST), multiple-slide technique (MuST), and tunica mesh expansion procedure (TMEP). Adjuvant techniques can also improve subjective penile length include, ventral phalloplasty, suprapubic lipectomy, suspensory ligament release and use of expanding penile implants. Preoperative protocols including use of a vacuum erectile device, traction therapy also seem to improve postoperative outcomes, minimizing postoperative pain, and encouraging the early device use. Currently, there is no consensus among experts on a particular lengthening procedure or when they can be performed to optimize outcomes. Furthermore, it is imperative to set proper expectations before surgery, with extensive patient and partner counseling. When used in the properly selected patient, penile lengthening procedures show promising results with minimal complication rates.

Project description:BackgroundTo test the feasibility of laparoscopic approach in performing the simultaneous pelvic autonomic nerve preservation during standard anterior resection of sigmoid colon cancer.MethodsPatients meeting appropriate eligibility criteria were recruited for the present study. The surgical procedures are shown in the video. The genitourinary function was evaluated on the basis of validated questionnaires including International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF), and Female Sexual Function Index (FSFI).ResultsA total of 112 patients (tumor, node, metastasis system stage I, n = 8; stage II, n = 54; stage III, n = 50; male, n = 58; female, n = 54; age [mean +/- standard deviation], 55.8 +/- 6.4 years) with good baseline genitourinary function were operated on with the intent of total preservation of pelvic autonomic nerves and curative resection of sigmoid colon cancer. The patients were prospectively followed (median time of follow-up, 18 months; range, 6-30 months). In patients with a successful nerve-preserving surgery (96.4%, n = 108), 104 patients completed the evaluation of urinary function. The median duration for indwelling urine Foley catheter was 3.0 days (range, 1.0-7.0 days). The voiding function after removal of the urine Foley catheter was good (IPSS, 0-7) in 98 (94.2%) patients, fair (IPSS, 8-14) in 5 (4.8%), and poor (IPSS, 15-35) in 1 (1.0%). Before and after nerve-preserving surgery, there were no significant changes of IPSS scores (3.20 +/- 1.72 vs. 3.68 +/- 2.82, P = .075, paired t-test) in the present patient series. Forty-four male patients completed the postoperative evaluation of sexual function, and ejaculation was ranked as good in 40 (90.9%), fair (decrease in ejaculatory amounts) in 3 (6.8%), and poor (retrograde ejaculation, failure of ejaculation) in 1 (2.3%), whereas the potency was good (IIEF, 60-75) in 41 (93.2%), fair (IIEF, 44-59) in 2 (4.5%), and poor (IIEF, 5-43) in 1 (2.3%). Moreover, before and after a successful nerve-preserving operation, there were no significant changes of IIEF scores (72.4 +/- 4.6 vs. 70.3 +/- 8.4, P = .082, paired t-test). For female patients (n = 42), the postoperative sexual function was ranked as good (FSFI score, 76-95) in 36 (85.7%), fair (FSFI, 58-75) in 4 (9.5%), and poor (FSFI, 4-57) in 2 (4.8%). Furthermore, there were no significant changes of FSFI scores (89.0 +/- 9.2 vs. 85.4 +/- 16.4, P = .122, paired t-test) before and after successful nerve-preserving surgery.ConclusionsUnder laparoscopy, we can clearly identify and preserve the pelvic autonomic nerves to retain genitourinary function in most patients undergoing oncologic resection of sigmoid colon cancer.
