Abstract
INTRODUCTION The incidence and clinical significance of postoperative urinary retention (POUR) remain high. This study aimed to evaluate the incidence of POUR and related risk factors in patients who underwent total mesorectal excision (TMR) for low rectal cancer. METHODS This study is a retrospective review of a prospectively collected colorectal database from a single center. Data from patients who underwent surgery for low rectal cancer between September 2006 and May 2017 were analyzed to assess the risk factors of POUR. POUR was considered inability to void after urinary catheter removal requiring catheter reinsertion and difficulty in bladder emptying requiring intermittent catheterization. RESULTS Of 555 patients with low rectal cancer, 78 (14.1%) developed POUR. Based on multivariate logistic regression analysis, laparoscopic TMR (odds ratio [OR]; 2.114, 95% confidence interval [CI]; 1.212-3.689, p = 0.008) and postoperative ileus (OR; 2.389, 95% CI; 1.282-4.450, p = 0.006) were independent risk factors of POUR. Male gender, advanced age, neoadjuvant chemoradiation, longer operative time, abdominoperineal resection, and lateral pelvic lymph node dissection were not associated with POUR. Advanced age over 65 years also failed to show statistical significance (OR; 1.604, 95% CI; 0.965-2.668, p = 0.068). CONCLUSION Laparoscopic approach and postoperative ileus are risk factors for POUR after low rectal cancer surgery. We postulate that the benefits of robotic surgical systems compared to a laparoscopic approach may reduce the incidence of POUR.

Abstract
PURPOSE Postoperative urinary retention (POUR) is a known morbidity after colorectal surgery. This study investigated the effect of prophylactic tamsulosin on urinary retention rates after colorectal surgery. METHODS A retrospective cohort study of male patients 50 years or older undergoing elective colonic and rectal resections from May 2014 to November 2019 was performed. The intervention assessed was prophylactic tamsulosin use. POUR, defined by requiring intermittent or reinsertion of urinary catheter, was compared using chi-squared analysis. RESULTS A total of 332 patients were included, 131 received no tamsulosin, and 201 received prophylactic tamsulosin. Overall POUR was significantly reduced (16.8% vs. 9.5%, p = 0.047). Subgroup analysis for age 50-59 revealed no difference (9.1% vs. 9.4%, p = 0.96), but POUR risk was significantly lower in age 60 and older (20.7% vs. 9.5%, p = 0.02). No significant difference was found in rectal resections alone (18.2% vs. 13.2%, p = 0.34). CONCLUSION Prophylactic tamsulosin reduced POUR after colorectal surgery with the greatest effect in men 60 years or older and colonic resections.

Abstract
Purpose Enhanced Recovery After Surgery (ERAS) programs advocate early urinary catheter removal after rectal cancer surgery; however, the optimal duration remains unclear. This study assessed the feasibility of the early urinary catheter removal protocol after rectal cancer surgery within an ERAS pathway and identified predictive factors for failure of this strategy. Methods Between March 2017 and October 2018, all unselected and consecutive patients who underwent rectal cancer resection and benefited from our ERAS program were included. Urinary complications (infection and retention) were prospectively recorded. Success was defined as catheter removal on postoperative day (POD) 3 without urinary complications. Results Of 135 patients (male, 63.7%; neoadjuvant chemoradiation, 57.0%; urology history, 17.8%), 120 had early urinary catheter removal with no complications (success rate, 88.9%), 8 did not have urinary catheter removal on POD 3 due to clinical judgment or prescription error, 5 experienced a urinary tract infection, and 2 had acute urinary retention. Obesity (odds ratio [OR], 0.16; P = 0.003), American Society of Anesthesiologists physical status classification > II (OR, 0.28; P = 0.048), antiaggregant platelet medication (OR, 0.12; P < 0.001), absence of anastomosis (OR, 0.1; P = 0.003), and prolonged operative time (OR, 0.21; P = 0.020) were predictive factors for failure. Conversely, optimal compliance with the ERAS program (OR, 7.68; P < 0.001), postoperative nonsteroidal anti-inflammatory drug use (OR, 21.71; P < 0.001), and balanced intravenous fluid therapy (OR, 7.87; P = 0.001) were associated with increased strategy success. Conclusion Withdrawal of the urinary catheter on POD 3 was successfully achieved after laparoscopic rectal resection and can be safely implemented in the ERAS program.

Abstract
AIM Urinary dysfunction is one of many complications after treatment for rectal cancer. The aim of this study was to evaluate the prevalence of patient-reported urinary dysfunction at the time of diagnosis and at 1-year follow-up and to assess the risk factors linked to urinary incontinence. METHOD Patients with newly diagnosed rectal cancer were included in the QoLiRECT study between 2012 and 2015. Questionnaires from the time of diagnosis and 1-year follow-up were analysed, with 1085 and 916 patients, respectively, eligible for analysis. Regression analyses were made to investigate possible risk factors for incontinence. The patient cohort was also compared with a cohort from the Swedish general population. RESULTS At baseline, the prevalence of urinary dysfunction (14% of women, 8% of men) was similar to that in the general population. At 1-year follow-up, 20% of patients experienced urinary incontinence (29% of women, 14% of men). Emptying difficulties were experienced by 46% (41% of women, 49% of men) and urgency by 58% across both sexes. Abdominoperineal excision and urinary dysfunction at baseline were found to be independent risk factors for incontinence at 1-year follow-up. Among patients who were continent at baseline, risk factors were female sex, physical inactivity at baseline, comorbidity and abdominoperineal excision. CONCLUSION Urinary dysfunction is frequent among patients with rectal cancer, with up to a two-fold increase in symptoms 1 year after diagnosis. Unfortunately, few factors are modifiable and these results stress the importance of informing patients of possible outcomes related to urinary dysfunction after treatment for rectal cancer.

Abstract
Poor early urinary outcomes after laparoscopy were reported in studies comparing laparoscopic versus open rectal cancer surgery. One possible explanation was that these studies might include a number of patients on the laparoscopic surgeons’ learning curve. This study aims to evaluate whether the learning curve of laparoscopic rectal cancer surgery influences early postoperative urinary dysfunction. Between September 2009 and December 2014, 208 consecutive patients undergoing laparoscopic rectal resection for rectal cancer were enrolled in the present study. All the clinical data were obtained from a prospectively compiled database. The primary outcomes were the incidences of postoperative urinary retention (POUR) and major urinary dysfunction requiring long-term urinary catheterization. POUR and major urinary dysfunction rate were 20.2 per cent (42/208) and 4.3 per cent (9/208), respectively. The learning curve analysis for operative time using the moving average method showed stabilization at 80 cases. Surgeon experience was divided into two periods: learning curve period (1–80 cases) and experienced period (81–208 cases). Multivariate analysis showed that older age (OR = 3.250, P = 0.006) and learning curve (OR = 2.241, P = 0.024) were independent risk factors for POUR. Learning curve was not significantly associated with increased rates of major urinary dysfunction (OR = 3.378, P = 0.092). Learning curve is a significant risk factor for increased rate of POUR after laparoscopic rectal cancer surgery. Technical training may be key to shorten the learning curve and limit its impact on the postoperative urinary complications.

Abstract
BACKGROUND Treatment modalities for rectal cancer, including radiation, are associated with urinary adverse effects. OBJECTIVE The purpose of this study was to determine the influence of surgery and radiation therapy for rectal cancer on long-term urinary complications. DESIGN Using the Surveillance Epidemiology and End Results-Medicare data set from the United States, patients with rectal cancer older than 66 years of age who underwent rectal resection between 1992 and 2007 were stratified into treatment groups that accounted for surgical resection and the timing of radiation therapy, if used. A control group of patients who did not have rectal cancer were matched by age, sex, demographics, and comorbidities. The primary outcome was a urinary adverse event defined as a relevant urinary diagnosis with an associated procedure. Patients with rectal cancer in different treatment groups were compared with control patients using a propensity-adjusted, multivariable Cox regression analysis. SETTINGS The study was conducted with the Surveillance Epidemiology and End Results-Medicare data set from the United States at our institution. RESULTS Of the 11,068 patients with rectal cancer, 56.2% had surgical resection alone, 21.7% received preoperative radiation, and 22.1% received postoperative radiation. The median follow-up for all of the groups of patients was >2 years. All of the groups of patients with rectal cancer were more likely to develop a urinary adverse event compared with control subjects. Adjusted HRs were 2.28 (95% CI, 2.02-2.57) for abdominoperineal resection alone, 2.24 (95% CI, 1.79-2.80) for preoperative radiation and surgical resection, 2.04 (95% CI, 1.70-2.44) for surgical resection and postoperative radiation, and 1.69 (95% CI, 1.52-1.89) for low anterior resection alone. LIMITATIONS Treatment patterns are somewhat outdated, with a large proportion of patients receiving postoperative radiation. The data did not allow for accurate assessment of urinary tract infections or mild urinary retention that is not managed with a procedure. CONCLUSIONS Rectal cancer surgery with or without radiation is associated with a higher risk of urinary complications requiring procedures. Patients who undergo low anterior resection without radiation tend toward the lowest risk for a urinary adverse event.

Abstract
Literature on postoperative urinary retention (POUR) after colorectal resections is limited. The aim of our study was to evaluate the incidence of and risk factors for POUR after elective colorectal resections in men ≥55 years without genitourinary issues. A retrospective review of elective colorectal resections (June 1, 2014 to June 1, 2015) in men ≥55 years without genitourinary conditions was performed at our institution. Patient demographics, American Society of Anesthesiologist score, body mass index (BMI), surgical history, type of disease, extent of resection, surgical approach, operating room (OR) time, volume of OR fluids administered, and intra- and postoperative urine output were included for analysis. Seventy patients were identified. Nine (12.9%) experienced POUR. Patients with POUR experienced longer OR time (324 vs 239 minutes; P = 0.048) and had a lower median BMI (23.8 vs 28 kg/m2; P = 0.038). There were no significant differences in regards to age, comorbidities, diagnosis, type of resection, surgical approach, intravenous fluids administered operatively, or postoperative urine output. The incidence of POUR in male patients at least 55 years of age after elective colorectal resection in our institution was 12.9 per cent. Longer operative time and lower BMI were associated with a higher incidence of POUR.

Abstract
A significant part of rectal cancer survivors will experience urogenital dysfunction induced by the treatment. Significant progress has been made in order to improve the total mesorectal technique through different approaches (open, laparoscopic, robotic, transanal). Rectal cancer surgery is technically difficult notably deep in the pelvis, and therefore the most frequent cause of the postoperative dysfunction is the surgical nerve damage of the autonomic nerves at this level. The main objectives of these efforts were to obtain maximal oncological results and to achieve better functional outcomes including less postoperative urogenital dysfunctions. Our purpose was to build a comprehensive review of the existing literature data regarding this issue from past to present.

Abstract
BACKGROUND Urinary retention after rectal resection is common and managed prophylactically by prolonging urinary catheterization. However, because indwelling urinary catheterization is a well-established risk factor for urinary tract infection, the ideal timing for urinary catheter removal following a rectal resection is unknown. OBJECTIVE We hypothesized that early urinary catheter removal (on or before postoperative day 2) would be associated with urinary retention. DESIGN This study is a retrospective review of medical records. SETTING This study was conducted at a colorectal surgery service at a tertiary care academic teaching hospital. PATIENTS Adults undergoing rectal resection operations by colorectal surgeons in 2005 to 2010 were selected. MAIN OUTCOME MEASURE The primary outcome measured was urinary retention. RESULTS Of 205 patients included, 41 (20%) developed urinary retention. Male sex (OR, 3.9; 95% CI, 1.7-9), increased intraoperative intravenous fluid (OR for each liter, 1.2; 95% CI, 1.04-1.48), and urinary catheter removal on postoperative day 2 or earlier (OR, 3.8; 95% CI, 1.4-10.5) were associated with urinary retention on multivariable analysis. Early catheter removal was not associated with decreased urinary tract infection rates (p = 0.29) but was associated with shorter length of stay (6.5 vs 8.9 days; p = 0.005). LIMITATIONS The retrospective nature of this study did not allow for a precise definition of urinary retention. Preoperative urinary function was not available, and the patient sample was heterogeneous, including several indications for rectal resection. Urinary catheters were not removed per protocol and therefore subject to bias. The study is likely underpowered to detect differences in urinary tract infection between urinary catheter removal groups. CONCLUSION In patients undergoing rectal resection, we found that urinary catheter removal on or before postoperative day 2 was associated with urinary retention (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A172).

Abstract
After colorectal resection surgery, early urinary catheter removal has been promoted as a part of the national Surgical Care Improvement Project. However, the decrease in urinary tract infection expected with this strategy must be balanced against an increased risk for urinary retention. A systematic review of the literature was undertaken to summarize the evidence for and against early postoperative urinary catheter removal. For nonpelvic colorectal resection, the evidence supports removal of the catheter on postoperative day 1 for patients who are not at high risk for urinary retention, including patients with thoracic epidurals. For mid-to-low rectal surgery, the risk of urinary retention is increased, and catheter removal on day 3 to day 6 is recommended; however, the exact timing of removal cannot be recommended based on current studies.

Abstract
PURPOSE We have developed nerve-oriented mesorectal excision (NOME) as a novel concept in rectal cancer surgery by which autonomic pelvic nerves serve as landmarks for a standardized navigation along fascial planes. This article describes the technique step by step and presents our results from 2008 to 2012. MATERIAL AND METHODS The key steps are: preparation of the splanchnic nerves at the mid-posterior sidewall, the hypogastric nerves at the upper sidewall, and the urogenital nerve branches (Walsh) at the caudal-anterior sidewall. The dissection of the lateral ligament is strictly performed as the last step. NOME was applied in 274 consecutive mesorectal excisions (partial 20.4%, total 79.6%); a subgroup of 42 male patients underwent a questionnaire-based interview on sexual activity. RESULTS The conversion rate was 0.7%. High (complete) specimen quality and circumferential margin negativity were achieved in 90.1% and 95.3%, respectively. Anastomotic leaks occurred in 13 (4.7%) patients. Mortality was 1.8%. The frequency of prolonged urinary catheter was 1.8%. Of 22 sexually active males interviewed, 18 (81.8%) maintained activity postoperatively. CONCLUSIONS NOME achieves high-quality mesorectal specimens and a high rate of preservation of autonomic nerve function. The concept of using nerves as laparoscopic landmarks may help to standardize and master laparoscopic rectal cancer surgery.

Abstract
AIMS Intraoperative neuromonitoring (IONM) aims to control nerve-sparing total mesorectal excision (TME) for rectal cancer in order to improve patients' functional outcome. This study was designed to compare the urogenital and anorectal functional outcome of TME with and without IONM of innervation to the bladder and the internal anal sphincter. METHODS A consecutive series of 150 patients with primary rectal cancer were analysed. Fifteen match pairs with open TME and combined urogenital and anorectal functional assessment at follow up were established identical regarding gender, tumour site, tumour stage, neoadjuvant radiotherapy and type of surgery. Urogenital and anorectal function was evaluated prospectively on the basis of self-administered standardized questionnaires, measurement of residual urine volume and longterm-catheterization rate. RESULTS Newly developed urinary dysfunction after surgery was reported by 1 of 15 patients in the IONM group and by 6 of 15 in the control group (p = 0.031). Postoperative residual urine volume was significantly higher in the control group. At follow up impaired anorectal function was present in 1 of 15 patients undergoing TME with IONM and in 6 of 15 without IONM (p = 0.031). The IONM group showed a trend towards a lower rate of sexual dysfunction after surgery. CONCLUSIONS In this study TME with IONM was associated with significant lower rates of urinary and anorectal dysfunction. Prospective randomized trials are mandatory to evaluate the definite role of IONM in rectal cancer surgery.

Abstract
BACKGROUND National quality initiatives have mandated the earlier removal of urinary catheters after surgery to decrease urinary tract infection rates. A potential unintended consequence is an increased postoperative urinary retention rate. OBJECTIVE The aim of this study was to determine the incidence and risk factors for postoperative urinary retention after colorectal surgery. DESIGN This was a prospective observational study. SETTINGS A colorectal unit within a single institution was the setting for this study. PATIENTS Adults undergoing elective colorectal operations were included. INTERVENTIONS Urinary catheters were removed on postoperative day 1 for patients undergoing abdominal operations, and on day 3 for patients undergoing pelvic operations. Postvoid residual and retention volumes were measured. MAIN OUTCOME MEASURES The primary outcomes measured were urinary retention and urinary tract infection. RESULTS The overall urinary retention rate was 22.4% (22.8% in the abdominal group, 21.9% in the pelvic group) and was associated with longer operative time and increased perioperative fluid administration. Mean operative time for those with retention was 2.8 hours and, for those without retention, the mean operative time 2.2 hours (abdominal group 2 hours vs 1.4 hours, pelvic group 3.9 hours vs 3.1 hours, p ≤ 0.02). Patients with retention received a mean of 2.7L during the operation, whereas patients without retention received 1.8L (abdominal group 1.9L vs 1.4L, pelvic group 3.6L vs 2.2L, p < 0.01). In the abdominal group, patients with and without retention also received different fluid volumes on postoperative days 1 (2.2L vs 1.7L, p = 0.004) and 2 (1.6L vs 1L, p = 0.05). Laparoscopic abdominal group had a 40% retention rate in comparison with 12% in the open abdominal group (p = 0.004). Age, sex, preoperative radiation therapy, preoperative prostatism, preoperative diagnosis, and level of anastomosis were not associated with retention. The urinary tract infection rate was 4.9%. LIMITATION The lack of documentation of preoperative urinary function was a limitation of this study. CONCLUSIONS The practice of earlier urinary catheter removal must be balanced with operative time and fluid volume to avoid high urinary retention rates. Also important is increased vigilance for the early detection of retention.

Abstract
BACKGROUND We conducted a randomized clinical trial to investigate the efficacy of the selective α(1A)-adrenoceptor antagonist tamsulosin in preventing acute voiding difficulty after rectal cancer surgery. METHODS A total of 94 rectal cancer patients with an International Prostate Symptom Score (IPSS) of ≤7 were randomly assigned (1:1) to the tamsulosin group (0.2 mg/day orally for 7 days) (n = 47) or the control group (n = 47). The primary endpoint was the reinsertion rate of the urinary catheter after its removal on postoperative day (POD) 3. The secondary endpoints included the maximum (Qmax) and average (Qavg) urinary flow rates on POD 3, and the voided volume (VV), residual urine volume (RU), and IPSS on POD 7. Analyses were based on an intention-to-treat population. RESULTS The reinsertion rate of the urinary catheter in the tamsulosin group was similar to that in the control group (23.4 vs. 21.3 %, respectively; p = 0.804). The postoperative voiding parameters and IPSS were not better in the tamsulosin group than in the control group after adjustments were made for the baseline measurements with analysis of covariance (Qmax, p = 0.537; Qavg, p = 0.399; VV, p = 0.645; RU, p = 0.703; IPSS, p = 0.761). Multivariate analysis revealed that being male was the only independent risk factor for reinsertion of the urinary catheter (odds ratio 0.239; 95 % confidence interval 0.069-0.823; p = 0.023). CONCLUSIONS This controlled trial showed that tamsulosin at 0.2 mg/day does not prevent acute voiding difficulty after rectal cancer surgery.

Abstract
UNLABELLED When compared with other EU countries, Poland is in the last place in terms of efficacy of rectal cancer treatment. In order to remedy this situation, in 2008 Polish centres were given the opportunity to participate in an international programme for evaluating the treatment efficacy.The aim of the study was to present the results obtained during the first two years of research. MATERIAL AND METHODS The study protocol covered 71 questions concerning demographic data, diagnostics, risk factors, peri- and post-operative complications, histopathology, and treatment plan at discharge. The patient and unit data were kept confidential. RESULTS From 1 January 2008 to 30 December 2009, there were 709 patients recorded, of which 55.9% were males. At least one risk factor was found in approx. 3/4 of patients, while approx. 1/3 of patients were classified to group 3 and 4 according to ASA. The mean distance of the tumour from the anal margin was 8.5 cm; approx. 70% of patients were in the clinical stages cT3 and cT4; metastases were observed in 18.8%. Transrectal endoscopic ultrasonography (TREUS) was performed in 23.7% of patients, magnetic resonance imaging (MRI) in 2.5% and computed tomography (CT) scan - in 48.1%. In close to half of the patients, anterior or low anterior resection of the rectum was performed, and abdominoperineal resection in 1/4 of the patients. Anastomotic leakage was seen in 3.8% of patients, while 1.8% died during hospitalisation. CONCLUSIONS It should be strived after that all the centres undertaking the treatment of rectal cancer should participate in the quality assurance programme. This should enable the achievement of good therapeutic results in patients with rectal cancer treated in Polish centres.

Abstract
AIM Intra-operative neuromonitoring is increasingly applied in several surgical disciplines and has been introduced to facilitate pelvic autonomic nerve preservation. Nevertheless, it has been considered a questionable tool for the minimization of risk, as the results are variable and might be misleading. The aim of the present experimental study was to develop an intra-operative neuromonitoring system with improved reliability for monitoring pelvic autonomic nerve function. METHOD Fifteen pigs underwent low anterior rectal resection with pelvic autonomic nerve preservation. Intra-operative neuromonitoring was performed under autonomic nerve stimulation with observation of electromyographic signals of the internal anal sphincter and bladder manometry. As the internal anal sphincter frequency spectrum during stimulation was found to be mainly in the range of 5-20 Hz, intra-operative neuromonitoring signals were postoperatively processed by implementation of matching band pass filters. RESULTS In 10 preliminary experiments, signal processing was performed offline in the postoperative analysis. Of 163 stimulations intra-operatively assessed by the surgeon as positive responses, 135 (83%) were confirmed after signal processing. In the following five consecutive experiments intra-operative online signal processing was realized and demonstrated reliable intra-operative neuromonitoring signals of internal anal sphincter activity with significant increase during pelvic autonomic nerve stimulation [0.5 μV (interquartile range = 0.3-0.7) vs 4.8 μV (interquartile range = 2.5-7.5); P < 0.001]. CONCLUSION Online signal processing of internal anal sphincter activity aids reliable identification of pelvic autonomic nerves with potential for improvement of intra-operative neuromonitoring in pelvic surgery.

Abstract
Purpose The aim of this study was to assess the voiding dysfunction after rectal cancer surgery with total mesorectal excision (TME). Methods This was part of a prospective study done in the rectal cancer patients who underwent surgery with TME between November 2006 and June 2008. Consecutive uroflowmetry, post-voided residual volume, and a voiding questionnaire were performed at preoperatively and postoperatively. Results A total of 50 patients were recruited in this study, including 28 male and 22 female. In the comparison of the preoperative data with the postoperative 3-month data, a significant decrease in mean maximal flow rate, voided volume, and post-voided residual volume were found. In the comparison with the postoperative 6-month data, however only the maximal flow rate was decreased with statistical significance (P=0.02). In the comparison between surgical methods, abdominoperineal resection patients showed delayed recovery of maximal flow rate, voided volume, and post-voided residual volume. There was no significant difference in uroflowmetry parameters with advances in rectal cancer stage. Conclusions Voiding dysfunction is common after rectal cancer surgery but can be recovered in 6 months after surgery or earlier. Abdominoperineal resection was shown to be an unfavorable factor for postoperative voiding. Larger prospective study is needed to determine the long-term effect of rectal cancer surgery in relation to male and female baseline voiding condition.

Abstract
PURPOSE The aim of this animal study was to investigate the effect of intraoperative pelvic nerve stimulation on internal anal sphincter electromyographic signals in order to evaluate its possible use for neuromonitoring during nerve-sparing pelvic surgery. METHODS Eight pigs underwent low anterior rectal resection. The intersphincteric space was exposed, and the internal (IAS) and external anal sphincter (EAS) were identified. Electromyography of both sphincters was performed with bipolar needle electrodes. Intermittent bipolar electric stimulation of the inferior hypogastric plexus and the pelvic splanchnic nerves was carried out bilaterally. The recorded signals were analyzed in its frequency spectrum. RESULTS In all animals, electromyographic recordings of IAS and EAS were successful. Intraoperative nerve stimulation resulted in a sudden amplitude increase in the time-based electromyographic signals of IAS (1.0 (0.5-9.0) μV vs. 4.0 (1.0-113.0) μV) and EAS (p < 0.001). The frequency spectrum of IAS in the resting state ranged from 0.15 to 5 Hz with highest activity in median at 0.77 Hz (46 cycles/min). Pelvic nerve stimulation resulted in an extended spectrum ranging from 0.15 to 20 Hz. EAS signals showed higher frequencies mainly in a range of 50 to 350 Hz. However, after muscle relaxation with pancuronium bromide, only the low frequency spectrum of the IAS signals was still present. CONCLUSIONS Intraoperative verification of IAS function by stimulation of pelvic autonomic nerves is possible. The IAS electromyographic response could be used to monitor pelvic autonomic nerve preservation.

Abstract
Sexual and urinary dysfunction occur frequently after rectal surgery. Total mesorectal excision (TME) is currently the optimal technique for resection of rectal cancer, providing superior carcinological and functional outcomes. Age, pre-operative radiation therapy, abdominoperineal resection, and surgery which fails to respect the "sacred planes" of TME are the four major risk factors for post-operative sexual and urinary sequelae. In the era of TME, postoperative sexual dysfunction ranges from 10-35%, depending on the scores used to assess it, while urinary sequelae have decreased to less than 5%. The place of laparoscopic surgery remains to be defined, particularly with respect to these complications. It is essential to inform the patient pre-operatively about the possibility of such disorders not only for patient informed consent but also to help with correct post-operative management of the problem. Management is multifaceted, and includes psychological, pharmacological, and sometimes surgical therapy.

Abstract
PURPOSE Urinary bladder drainage for several days after pelvic surgery is a common surgical practice, despite insufficient evidence supporting its routine use. The aim of this study was to prospectively evaluate the utility of urinary bladder drainage after pelvic colorectal surgery. METHODS Patients undergoing pelvic surgery were prospectively randomly assigned to 3 groups. In group A, the Foley catheter was removed on postoperative day 1, and in groups B and C it was removed on postoperative days 3 and 5, respectively. Male patients with severe prostatic symptoms were excluded from the study. The main outcome criterion was acute urinary retention requiring reinsertion of the Foley catheter. RESULTS A total of 118 patients (68 males) at a mean age of 55 years were included in this study (group A, 41 patients; group B, 38; and group C, 39). Overall, urinary retention after removal of the Foley catheter occurred in 12 (10%) of the patients: 6 (14.6%) in group A, 2 (5.3%) in group B, and 4 (10.5%) in group C (P = .39). Symptomatic urinary tract infection was diagnosed in 5 patients in group A, 3 in group B, and 9 in group C, but this difference did not reach statistical significance. Likewise, there were no significant differences in anastomotic leak and intra-abdominal abscess rates among the 3 groups. CONCLUSIONS Routine prolonged urinary bladder catheterization after pelvic surgery may not be required, and the Foley catheter may be safely removed on postoperative day 1. Larger studies are needed to confirm the findings of this study.

Abstract
BACKGROUND AND AIMS The aim of this study was to investigate sexual function and the presence of lower urinary tract symptoms (LUTS) in male patients with rectal cancer following short-term radiotherapy and laparoscopic total mesorectal excision (LTME) by physical and psychological measurements. MATERIALS AND METHODS Sexual function and LUTS were assessed by the use of questionnaires [International Index of Erectile Function (IIEF), International Prostate Symptom Score]. Sexual function was further assessed by the use of pharmaco duplex ultrasonography of the cavernous arterial blood flow and nocturnal penile tumescence and rigidity monitoring (NPTR). All investigations were performed prior to the start of preoperative radiotherapy and 15 months after surgery. RESULTS Nine patients (mean age 60 years) participated. Erectile function was maintained in 71% and ejaculation function in 89%. Compared with pre-operative scores on the IIEF, a significant deterioration in intercourse satisfaction was seen following radiotherapy and LTME (7.9 vs 10.3, p = 0.042), but overall satisfaction remained unchanged (8.0 vs 7.0, p = 0.246). NPTR parameters (duration of erectile episodes, duration of tip rigidity > or =60%) decreased following radiotherapy and LTME. Patients reported a deterioration in micturition frequency (2.0 vs 1.0, p = 0.034) and quality of life due to urinary symptoms (8.0 vs 1.8, p = 0.018). CONCLUSION Based on these first preliminary findings, data suggest that 15 months after short-term radiotherapy and LTME in men with rectal cancer, objectively assessed sexual dysfunction was considerable, but overall sexual satisfaction had not changed.

Abstract
BACKGROUND Bladder dysfunctions are well-recognized complications after nerve-sparing mesorectal excision for rectal cancer. This study sought to symptomatically analyze the extent of recovery from major and minor urinary symptoms in patients with signs of bladder denervation. METHODS Sixty-two patients with mesorectal excision for rectal cancer were investigated prospectively. Pelvic autonomic nerve preservation (PANP) was assessed macroscopically and with the aid of intraoperative electrical stimulation of pelvic autonomic nerves (INS). Bladder function was evaluated with the International Prostate Symptom Score (IPSS) and the Quality of life index (Qol). Median follow-up was 20 months (range 3-40 months). RESULTS Forty-six patients with INS-confirmed preservation of parasympathetic nerves remained unchanged in early and long-term urinary function (IPSS: median 1; range 0-24 and Qol 0; range 0-5). In 15 patients without confirmation of PANP (unilaterally or bilaterally) on INS, voiding function was significantly more impaired postoperatively (IPSS: median 10; range 0-25 and Qol 3; range 0-6) and at long-term follow-up (IPSS: median 9; range 0-25 and Qol 3; range 0-6) (p<0.001). Voiding function was improved in 4 of 10 patients with major and minor symptoms. In 5 of 6 patients with long-term bladder dysfunction INS assessed parasympathetic nerve damage unilaterally (3/5) and bilaterally (2/5). CONCLUSION Long-term voiding disturbance after mesorectal excision was found to be a serious complication. INS while monitoring intravesical pressure is a valuable aid in predicting long-term bladder function after TME. The device may serve a secondary preventive function in enabling the initiation of early urologic therapy.

Abstract
PURPOSE The risk factors for postoperative urinary retention after colorectal carcinoma surgery can be clearly defined. This study was designed to determine risk factors for postoperative urinary retention after colorectal cancer surgery. METHODS A total of 2,355 consecutive patients with colorectal cancer who underwent open resection for colorectal cancer during a four-year period were included. The association between dependent and independent variables (including 19 clinicopathologic and surgical factors) was analyzed by using the chi-squared test or Fisher's exact test, as appropriate. The significant variables in the univariate analyses were included in multivariate analysis. RESULTS The overall prevalence of postoperative urinary retention was 5.5 percent (colon cancer, 1.7 percent; rectal cancer, 9.1 percent, P < 0.0001). Multivariate analysis showed an independent association between postoperative urinary retention and age, lung disease, tumor location, operation duration, and additional pelvic procedure. Of the 121 patients with postoperative urinary retention, urine catheterization was required in 42 patients one month postoperatively. Discriminate analysis showed that gender, American Society of Anesthesiologists' score, tumor location, presence of drainage, and pelvic infection were best able to discriminate between prolonged (>1 month) and transient urinary dysfunction. CONCLUSIONS Older patients, lung disease, rectal cancer, longer operation duration, and additional pelvic procedure were at greater risk. There is a time-dependent change in postoperative urinary dysfunction. Male gender, American Society of Anesthesiologists' score of 2 or 3, rectal tumor, surgical drain, and pelvic infection can identify patients at risk for prolonged urinary dysfunction.

Abstract
BACKGROUND To improve nerve-sparing surgery, intraoperative electrical stimulation of pelvic autonomic nerves (INS) has been proposed in urology, gynecology, and visceral surgery. The aim of this study was to assess the impact of INS while monitoring intravesical pressure on the accurate evaluation of pelvic autonomic nerve preservation (PANP) after mesorectal excision. It was sought to determine whether this confirmation is useful in the prediction of postoperative urinary function. METHODS Sixty-two patients with mesorectal exzision for rectal cancer were examined prospectively. PANP was assessed visually by the surgeon and with INS. Bladder function was evaluated by post voiding residual volume measurement, rate of recatheterization, rate of long-term urinary catheterisation, and the international prostatic symptom score with quality of life index. RESULTS INS confirmed bilateral preservation of parasympathetic nerves in 46 patients (74%), and in 10 patients (16%) in at least one side. In six patients (10%), INS failed to confirm PANP. Eleven patients (18%) developed urinary symptoms postoperatively. INS results had a higher sensitivity than visual assessment by the surgeon (82 vs 46%). Values for specificity ranged at 90 and 92%, respectively. Accuracy of INS in predicting PANP was higher (88 vs 83%). The correlation between urinary function and the findings on INS was good (kappa-value: 0.65), correlation between urinary function and visual assessment by the surgeon was fair (kappa-value: 0.40). CONCLUSION INS, while monitoring intravesical pressure, accurately predicts bladder function after mesorectal excision. It may provide further insight into pelvic autonomic nerve sparing techniques.

Abstract
BACKGROUND This study aimed to prospectively evaluate operative safety and mid-term oncologic outcomes of laparoscopic rectal cancer resection performed by a single surgeon. METHODS Three hundreds twelve patients (male, 181) were enrolled in this analysis. 257 patients (82.4%) had tumors located below 12 cm from the anal verge. Distribution of TNM stages was 0:I:II:III:IV = 4.2%:17.9%:32.4%:37.2%:8.3%. 225 patients (71.1%) had T3/T4 lesions. Pre- and post-operative radiation was given in 6 and 20 patients, respectively. RESULTS Sphincter-preserving operation was performed in 85.9%. Mean operating time was 212 minutes. Conversion rate was 2.6%. Overall morbidity rate was 21.1%. Anastomotic leakage occurred in 6.4%. Operative mortality rate was 0.3%. Mean number of harvested nodes was 23. Mean distal tumor-free margin was 2.8 cm. The circumferential resection margin was positive in 13 patients (4.2%). With a mean follow-up of 30 months in the stage I-III patients, the local recurrence rate was 2.9%. Systemic recurrence occurred in 11.7%. No port-site recurrence was observed. CONCLUSION Laparoscopic resection of rectal cancer provided safe operative parameters and adequate mid-term oncologic outcomes. When considering a high volume of advanced and low-lying cancers but rather narrow indication to radiotherapy, the 2.9% local recurrence rate seems promising data. Long-term follow-up is mandatory to draw conclusion.

Abstract
PURPOSE The need for monitoring postoperative urine output and the possibility of lower urinary tract dysfunction following colorectal surgery necessitates temporary urinary drainage. Current practice assumes recovery of lower urinary tract function to coincide with successful micturition after removal of urethral catheter. The aim of this study was to analyze the recovery of bladder function following colorectal surgery. METHODS Patients undergoing colorectal operations underwent preoperative and postoperative uroflowmetry and residual urine estimation. All patients were catheterized suprapubically at surgery. Uroflowmetry and postvoid residual volumes were recorded postoperatively until recovery of bladder function was complete. RESULTS Thirty consecutive patients underwent suprapubic catheterization, 25 of whom completed the study. Seventeen (68 percent) patients were able to pass urine within 72 hours of surgery. Recovery of lower urinary tract function was delayed in patients undergoing rectal vs. colonic resections (median, 6 vs. 3 days, P = 0.0015). Postvoid residual volumes greater than 200 ml were noted in three (20 percent) patients following rectal resections beyond the tenth postoperative day, with complete emptying achieved by six weeks. CONCLUSIONS Apparent successful micturition following rectal resections does not always indicate recovery of bladder function. The use of suprapubic catheters, in addition to being safe and effective, allows assessment of residual volumes postoperatively and smoothes the path to full recovery of lower urinary tract function.
