Can bipolar transurethral enucleation of the prostate be a better alternative to the bipolar transurethral resection of the prostate?: A prospective comparative study.

ABSTRACT: To analyze the efficacy and safety between bipolar transurethral enucleation of the prostate (BipoLEP) and bipolar transurethral resection of the prostate (B-TURP).One hundred twenty eight patients with benign prostatic hyperplasia were recruited and divided into group 1 (BipoLEP group, n = 72) and group 2 (B-TURP group, n = 56). The study period was from October 2016 to February 2019. All data parameters were prospectively collected and analyzed.In these 2 groups, there were no significant differences of the mean ages (71.88 ±â€Š6.54 years vs 73.05 ±â€Š7.05 years, P = .407), prostate volumes (99.14 ±â€Š9.5 mL vs 95.08 ±â€Š10.93 mL, P = .302) and the mean operation times (93.7 ±â€Š27.5 minutes vs 89.8 ±â€Š22.4 minutes, P = .065). In BipoLEP group, it had more prostate tissue resected (64.2 ±â€Š22.1 g vs 52.7 ±â€Š28.6 g, P = .018), less duration of continuous bladder irrigation (20.7 ±â€Š6.5 hours vs 29.6 ±â€Š8.3 hours, P = .044), shorter catheterization time (4.3 ±â€Š1.5 days vs 5.6 ±â€Š2.1 days, P = .032), shorter hospitalization stay (5.2 ±â€Š1.4 days vs 6.5 ±â€Š1.9 days, P = .031) and less complications (3 cases vs 9 cases, P = .021). There were significant improvements in 3-month postoperative parameters, including: post void residual urine, maximum flow rate, International Prostatic Symptoms Scale, and quality of life in each group (p < 0.01). However, there were no significant differences of preoperative and 3-month postoperative parameters, including: post void residual urine, maximum flow rate, International Prostatic Symptoms Scale, and quality of life between these 2 groups (P > .05).BipoLEP can produce a more radical prostatic resection with better safety profile and faster postoperative recovery. It may become a more favorable surgical alternative to the B-TURP, especially for the prostate larger than 80 g.

Adherence with bladder irrigation following augmentation.

BACKGROUND: Patients with bladder augmentation (BA) are routinely counseled to irrigate their bladders daily. However, reports of adherence with this regimen are lacking. OBJECTIVE: To evaluate adherence to a bladder irrigation protocol and identify risk factors associated with adherence among adults with spina bifida (SB) and BA. STUDY DESIGN: Adults with SB after BA followed in a multidisciplinary clinic were identified (2017-2019). All patients or caregivers were taught the importance of and the technique for the bladder irrigation protocol prior to and after BA. Patient demographics (age, gender, ambulatory status, and presence of a caregiver in clinics) and surgical details (type of BA, age at surgery, length of follow-up, presence of a catheterizable channel, position of stoma, bladder neck surgery, presence of Malone antegrade colonic enema or ventriculo-peritoneal shunt, and number of stone surgeries) were obtained from the medical record. Patients reported other variables in a standardized clinic questionnaire. Answers were confirmed by health care providers. The variables included who performs clean intermittent catheterization (CIC), size of catheter, frequency of CIC, use of overnight catheterization, difficulties with CIC, number of UTIs, and continence per urethra and per catheterizable channel. Adherence to bladder irrigation was also assessed in the questionnaire. ?Strict adherence' was defined as bladder irrigation performed ≥6 times/week with ≥120 mL of saline. For statistical analysis, a more lenient definition of ?higher adherence' was used: bladder irrigation ≥2 times/week with at least 60 mL. ?Lower adherence' was defined as ≤1 time/week or with less than 60 mL. Factors associated with ?higher adherence' were assessed with non-parametric tests (Bonferroni-corrected p-value: 0.002). RESULTS: Adherence was assessed in 87 eligible patients (60.9% females; mean age of 28.8 ± 8.2 years). No patient (0.0%) reported ?strict adherence', and 62 and 25 patients (71.3% and 28.7%) reported ?higher' and ?lower' adherence' to bladder irrigation, respectively. Nine patients (10.3%) in the ?lower adherence' group did not irrigate at all. No variables were statistically significant on univariate analysis, including previous bladder stone surgery or having a channel (p ≥ 0.01). On exploratory analysis, higher adherence was only associated with self-catheterizations versus those performed by caregivers (76.7% vs 33.3%, p = 0.01). CONCLUSIONS: Adherence to a bladder irrigation protocol in adults with SB and BA is poor. A history of bladder stones requiring surgery and the presence of a catheterizable channel do not appear to affect adherence. It remains unclear why some patients are more likely than others to irrigate their bladders. Future work will focus on methods to improve adherence.

Rectal Douching Practices Associated with Anal Intercourse: Implications for the Development of a Behaviorally Congruent HIV-Prevention Rectal Microbicide Douche.

Tenofovir administration via rectal douching results in higher rectal-mucosa drug concentration than oral administration. Many who engage in receptive anal intercourse (RAI) use cleansing rectal douches. To inform development of a behaviorally-congruent tenofovir douche, 4751 individuals ≥ 18 years-old, born male, from all US states/territories, who engaged in anal intercourse responded to an online survey. Of those who reported RAI in the prior 3 months, 80% douched beforehand, 82% within 1 h, mean 2.9 consecutive applications; 27% douched afterwards, 83% within 1 h, mean 1.7 consecutive applications. Among multidose users, 78% applied doses within 2 min, and 76% retained liquid < 1 min. Most used tap water (89%) in an enema bottle (50%) or rubber bulb (43%), and douched for cleanliness (97%), to avoid smelling bad (65%), and to enhance pleasure (24%). 98% reported high likelihood of using an HIV-prevention douche. An ideal product will protect within a user's typical number of applications, within 1 h, and be dissolvable in tap water.

[Low-concentration hydrogen peroxide solution for continuous bladder irrigation after transurethral resection of the prostate].

OBJECTIVE: To evaluate the effectiveness and safety of low-concentration hydrogen peroxide solution (HPS) for continuous bladder irrigation after transurethral resection of the prostate (TURP). METHODS: We retrospectively analyzed the clinical data about 148 cases of benign prostatic hyperplasia (BPH) treated by TURP from January 2013 to January 2016. Seventy-six of the patients received postoperative continuous bladder irrigation with 0.15% HPS (group A) and the other 72 with normal saline (group B). We compared the two groups of patients in their postoperative hemoglobin (Hb) levels, duration of bladder irrigation, frequency of catheter blockage, time of catheterization, and length of hospital stay. RESULTS: There were no statistically significant differences between the two groups of patients preoperatively in the prostate volume, International Prostate Symptoms Score, maximum urinary flow rate, postvoid residual urine, or levels of serum PSA and Hb (P > 0.05). At 48 hours after operation, a significantly less reduction was observed in the Hb level in group A than in group B (ï¼»3.38 ± 2.56ï¼½ vs ï¼»7.29 ± 6.58ï¼½ g/L, P < 0.01). The patients of group A, in comparison with those of group B, also showed remarkably shorter duration of postoperative bladder irrigation (ï¼»32.57 ± 5.99ï¼½ vs ï¼»46.10 ± 8.79ï¼½ h, P < 0.01), lower rate of catheter blockage (3.3% vs 11.8%, P < 0.01), shorter time of catheterization (ï¼»3.74 ± 0.79ï¼½ vs ï¼»4.79 ± 0.93ï¼½ d, P < 0.01), and fewer days of postoperative hospital stay (ï¼»4.22 ± 0.81ï¼½ vs ï¼»4.67 ± 0.88ï¼½ d, P < 0.01). CONCLUSIONS: Low-concentration HPS for continuous bladder irrigation after TURP can reduce blood loss, catheter blockage, bladder irrigation duration, catheterization time, and hospital stay, and therefore deserves a wide clinical application.

Effect of rectal douching/enema on rectal gonorrhoea and chlamydia among a cohort of men who have sex with men on HIV pre-exposure prophylaxis.

OBJECTIVES: Rectal douching/enema (RD) is a common practice among men who have sex with men (MSM) in preparation for sex. RD can break down the rectal mucosal barrier and potentially affect the rectal microbiome. The objective of this study was to understand if RD is associated with acquiring rectal infections (RI) with rectal gonorrhoea (NG) and/or chlamydia (CT). METHODS: From 2013 to 2015, 395 adult HIV-uninfected MSM were enrolled in a randomised controlled study for pre-exposure prophylaxis (PrEP) adherence with routine sexual risk survey and testing. Using data from this cohort, baseline differences by RI were assessed using Pearson's χ² and Wilcoxon-Mann-Whitney test. Association between RD and RI was modelled using multivariable logistic regression adjusted for potential confounders (sexual behaviour, substance use and age) selected a priori. Effect modification by number of male partners and sensitivity analysis to rule out reverse causality were also conducted. RESULTS: Of 395 participants, 261 (66%) performed RD and 133 (33%) had at least one NG/CT RI over 48 weeks. Number of condomless anal receptive sex (med: 4, p<0.001), male partners (med:6, p<0.001) and substance use (any of methamphetamine/hallucinogens/dissociative/poppers) (p<0.001) were associated with increased odds of RI. Controlling for potential confounders, odds of prevalent RI were 3.59 (p<0.001, 95% CI 1.90 to 6.78) and incident RI 3.87 (p=0.001, 95% CI 1.78 to 8.39) when douching weekly or more compared with not douching. MSM with more than six male partners had 5.34 (p=0.002, 95% CI 1.87 to 15.31) increased odds of RI when douching weekly or more compared with not douching. CONCLUSION: Rectal hygiene with RD is a common practice (66%) among HIV-uninfected MSM on PrEP in this study, which increases the odds of acquiring rectal NG and/or CT independent of sexual risk behaviour, substance use and other factors. This suggests interventional approaches targeting rectal hygiene products and practices could reduce sexually transmitted infections.

Rectal Douching Prevalence and Practices Among Peruvian Men Who have Sex with Men and Transwomen: Implications for Rectal Microbicides.

Peruvian men who have sex with men (MSM) and transwomen (TW) could benefit from a rectal microbicide (RM) formulated as a rectal douche to prevent HIV infection. However, little is known about rectal douching practices among Peruvian MSM and TW, information necessary to inform RM douche development and future uptake. Using a self-administered interview, we examined the prevalence of and factors associated with rectal douching among a convenience sample of 415 Peruvian MSM and 68 TW. In the previous 6 months, 18 % of participants reported rectal douching using pre-filled commercial kits or plastic bottles or enema bags filled with water, water/soap or saltwater. Multivariate logistic analysis found that "equally insertive and receptive" or "exclusively/mainly receptive" sex roles were associated with douche use. Rectal douching among Peruvian MSM and TW is similar to reports from other studies and supports the potential uptake of a douche-formulated RM in these populations.

Practice of first aid in burn related injuries in a developing country.

INTRODUCTION: First aid with cool running water reduces the severity of burn. Low level of knowledge of first aid in burns was shown in previous studies with few patients receiving first aid by water lavage. A study investigating the use of water lavage as first aid in patients presenting to hospital with burn in Lagos, Nigeria was carried out. METHODS: Patients admitted to a University Teaching Hospital for treatment of burns were recruited for this prospective study. Data detailing demographics, scene and aetiology of burns, material used for first aid, who administered first aid, level of education and relationship of first-aider with patients, length of hospital stay, complications and outcome of treatment were collected and statistical analysis performed. RESULTS: 168 patients; 73 (43.4%) children and 95 (56.6%) adults were seen. Burns were sustained at home in 95 (74.2%) cases and outside in 33 (25.8%). Water lavage was used in 49 (29.2%) cases, raw eggs in 21 (12.5%), pap in 16 (9.5%) and other materials in 48.8%. 40 (23.8%) patients had not received any form of first aid at presentation. Patients that received no water first aid had higher complication rate (35.3% versus 18.4%) compared with those that had water first aid. CONCLUSION AND RECOMMENDATIONS: The use of water first aid in burns was shown to reduce complication rate in this study. People should be educated on the efficacy of water first aid in pre-hospital care of burns.

An epidemiologic analysis of clinical practice guidelines for non-arthroplasty treatment of osteoarthritis of the knee.

PURPOSE: To analyze the current practice patterns of non-arthroplasty treatment of knee osteoarthritis (OA) and to assess the impact of the American Academy of Orthopaedic Surgeons clinical practice guidelines on the management of OA of the knee, particularly as they relate to the use of arthroscopic treatment. METHODS: The United Healthcare Database (2004-2009, 11 million patients, 216 million records) was used for the study and was searched using Boolean language for International Classification of Diseases, Ninth Edition, Clinical Modification and Current Procedural Terminology, fourth revision codes. A reference group was defined as patients treated with knee arthroplasty in 2009 and diagnosed with knee OA in the same record. Clinical practice patterns in the 5 years preceding arthroplasty were analyzed in this group. RESULTS: The reference group consisted of 12,806 patients undergoing total knee arthroplasty in 2009 with a documented diagnosis of OA at the time of surgery, with prior nonoperative treatment strategies analyzed during the preceding 5 years (2004-2009); 10.0% of patients were prescribed physical therapy specific to OA, 2.6% received an unloader brace, 0.52% underwent acupuncture, 43.5% were administered intra-articular corticosteroids, and 15.4% received viscosupplementation injections. During the 5 years before arthroplasty, 2,505 patients (19.6%) underwent arthroscopy and debridement/lavage, 35% of whom did not have a diagnosis code for mechanical pathology. Within 1 year of knee arthroplasty, 2,028 of the 2,505 knee arthroscopies (80.9%) were performed. CONCLUSIONS: The findings show that significant gaps do exist between the evidence-based American Academy of Orthopaedic Surgeons recommendations and actual practice patterns in the United States between 2004 and 2009. LEVEL OF EVIDENCE: Level IV, diagnostic study.

Enema use among men who have sex with men: a behavioral epidemiologic study with implications for HIV/STI prevention.

Enema use or douching is a risk factor for HIV/STI in men who have sex with men (MSM). However, few studies have explored enema use practices. We examined the frequency of enema use, type of products used, and reasons to use and not to use before and after receptive anal sex in a large sample of MSM (N = 4,992) recruited from 16 U.S. cities. Through online surveys, we examined personal, behavioral, and environmental factors associated with enema use. Most (52 %) participants reported having douched at least once and 35 % reported douching within the last 3 months. While most (88 %) reported enema use before receptive anal sex, 28 % douched after receptive anal sex. Most participants (65 %) used water to douche, 24 % added salt, soap, and/or antibacterial products to water, and 30 % reported using commercially available products. Being a man of color, HIV-positive, diagnosed with an STI, identifying as "versatile" in sex, and having more than two unprotected sex partners were significantly associated with recent enema use. Douching behavior appears closely associated with HIV/STI risk. Douching with water may be a concern since it may increase HIV/STI infection by damaging the epithelium. Development and promotion of a non-damaging, non-water based enema specifically for use in anal sex are recommended. In addition, the seemingly contradictory recommendations that water-based lubricant is recommended for anal sex but water-based enemas are dangerous need to be reconciled into a single consistent message.

Survey of arthroscopy performed by rheumatologists.

OBJECTIVE: To determine the international distribution and practice of arthroscopy performed by rheumatologists and to evaluate proposed guidelines on minimum standards for training in arthroscopy in the context of current clinical practice. METHODS: A questionnaire was sent to all rheumatology centres identified as practising arthroscopy, by (i) searching Medline from 1966 to 1999, (ii) searching the abstract books of the annual general meetings of ACR, BSR and EULAR from 1980 to 1999, and (iii) correspondence with all the centres identified. RESULTS: Thirty-six rheumatology centres were confirmed as performing arthroscopy (24 in Europe, 10 in USA and two in Australia) and 33 (92%) centres completed the questionnaire. Twenty-five (76%) of the 33 centres performing arthroscopy had started to perform it since 1990 and 72 rheumatologists are now trained in arthroscopy. A total of 16532 arthroscopies had been performed (median=220 arthroscopies/centre, range 20-5000); 50.5% of the arthroscopies had a primary clinical indication and 49.5% had a primary research indication. Most centres fulfilled the minimum standards for arthroscopic facilities and the proposed minimum standards in training were acceptable to 76% of respondents. Complication rates were calculated for 15682 arthroscopies where routine follow-up data were available [joint infection, 16 (0.1%); wound infection, 17 (0.1%); haemarthrosis, 141 (0.9%); deep venous thrombosis, 31 (0.2%); neurological damage, 3 (0.02%), thrombophlebitis, 12 (0.08%), other, 8 (0.06%)]. Irrigation volume correlated with wound infection rate (r=0.41, P=0.03) and centres performing cartilage biopsy had a higher rate of haemarthrosis (P=0.007). CONCLUSION: The last decade has seen rapid growth in arthroscopy performed by rheumatologists in an out-patient setting under local and regional anaesthesia. Proposed minimum standards for training in rheumatological arthroscopy reflect current practice accurately and are acceptable to the majority of arthroscopists. Complication rates of rheumatological arthroscopy are similar to those reported in the orthopaedic literature.
