Perioperative and functional outcomes of salvage versus primary Holmium laser enucleation of the prostate: Evidence-based on controlled studies.

To evaluate the perioperative and functional outcomes of holmium laser enucleation of the prostate (HoLEP) among patients with and without prior transurethral prostate surgery. we performed a systematic search of the Cochrane Library, PubMed, Embase, Web of Science and Scopus databases for articles evaluating the effectiveness of salvage HoLEP (S-HoLEP) versus primary HoLEP (P-HoLEP) until January 2023. Nine studies involving 6044 patients were included for both quantitative and qualitative analysis. Compared with P-HoLEP, S-HoLEP used more energy (weighted mean difference = 14.27 KJ; 95% CI = 4.75-23.79; P = 0.003) and had an increased incidence of postoperative clot retention (odds ratio = 2.12; 95% CI = 1.25-3.59; P = 0.005) and urethral stricture (OR = 1.99; 95% CI = 1.04-3.8; P = 0.04). However, the International Prostate Symptom Score at the sixth month of follow-up was significantly lower for S-HoLEP than for P-HoLEP (WMD = -0.80; 95% CI = -1.38 to -0.22; P = 0.007). There was no significant difference between S-HoLEP and P-HoLEP in terms of operative time, enucleation time, enucleation efficiency, morcellation time, resected weight, catheterisation time, hospital stay duration, quality of life, maximum urinary flow rate, postvoid residual and intraoperative and postoperative overall complications. compared with P-HoLEP, S-HoLEP is still a feasible and effective method for treating residual benign prostatic hyperplasia, with only a slight increase in the probability of energy utilisation, clot retention and urethral stricture. Despite these minor discrepancies, the overall beneficial effects of the two modalities on symptom resolution is noteworthy.

Risk factors for bladder neck contracture after transurethral resection of the prostate.

INTRODUCTION: Transurethral resection of the prostate (TURP) is the most frequently used treatment of benign prostate hyperplasia with a prostate volume of <80 mL. A long-term complication is bladder neck contracture (BNC). The aim of the present study was to identify the risk factors for BNC formation after TURP. METHODS: We conducted a retrospective analysis of all TURP primary procedures which were performed at one academic institution between 2013 and 2018. All patients were analyzed and compared with regard to postoperative formation of a BNC requiring further therapy. Uni- and multivariable logistic regression analyses (MVAs) were performed to identify possible risk factors for BNC development. RESULTS: We included 1368 patients in this analysis. Out of these, 88 patients (6.4%) developed BNC requiring further surgical therapy. The following factors showed a statistically significant association with BNC development: smaller preoperative prostate volume (p = 0.001), lower resected prostate weight (p = 0.004), lower preoperative levels of prostate-specific antigen (PSA, p < 0.001), shorter duration of the surgery (p = 0.027), secondary transurethral intervention (due to urinary retention or gross hematuria) during inpatient stay (p = 0.018), positive (≥100 CFU/mL) preoperative urine culture (p = 0.010), and urethral stricture (US) formation requiring direct visual internal urethrotomy (DVIU) postoperatively after TURP (p < 0.001), in particular membranous (p = 0.046) and bulbar (p < 0.001) strictures. Preoperative antibiotic treatment showed a protective effect (p = 0.042). Histopathological findings of prostate cancer (PCA) in the resected prostate tissue were more frequent among patients who did not develop BNC (p = 0.049). On MVA, smaller preoperative prostate volume (p = 0.046), positive preoperative urine culture (p = 0.021), and US requiring DVIU after TURP (p < 0.001) were identified as independent predictors for BNC development. CONCLUSION: BNC is a relevant long-term complication after TURP. In particular, patients with a smaller prostate should be thoroughly informed about this complication.

Urethral and bladder neck stenosis after thulium laser enucleation of the prostate: Analysis of risk factors in a series of 1003 patients.

We assessed the incidence and risks factors of bladder neck and urethral stenosis after Thulium laser enucleation of the prostate. Patients who underwent surgery at two centres were retrospectively reviewed (December 2014-June 2020). Exclusion criteria: previous urethral/prostatic surgery, pelvic irradiation, prostate cancer, neurogenic bladder, history of bladder neck and urethral stenosis, concomitant transurethral surgery, active urinary tract infection. Significant variables at univariate analysis (p < 0.05) were included in a multivariate logistic regression analysis to establish their association with bladder neck/urethral stenosis. One thousand and three patients were included. Median age was 69.0 (63.0-75.0) years. Median prostate volume was 65.0 (46.3-82.0) ml. Median follow-up was 31 (25-75) months. Thirty patients (2.99%) developed bladder neck stenosis [median time after surgery: 15 (11-17.75) months], 50 patients (4.98%) urethral stenosis [median time after surgery: 9 (7-11) months]. Men with bladder neck and urethral stenosis had significantly smaller prostate volume (median volume 43.5 ml vs. 66.0 ml, p = 0.008, and 52.0 ml vs. 66.0 ml, p = 0.009, respectively). At multivariable analysis, short surgical time predicted for bladder neck stenosis (OR 0.973; 95% CI 0.957-0.994, p = 0.002), and re-catheterization (OR 3.956; 95% CI 1.867-8.382, p < 0.001) for urethral stenosis, whereas prostate volume was significantly associated with a lower incidence of US (OR 0.984, 95% CI 0.972-0.998, p = 0.03).

The role of prostate inflammation in the pathogenesis of urethral strictures occurring after transurethral resections.

OBJECTIVE: To make an extensive evaluation about the effects of histopathological findings acquired from the resection materials of patients who underwent transurethral resection of prostate (TUR-P) due to benign prostate hyperplasia (BPH) on postoperative urethral stricture formation. MATERIALS AND METHODS: Among patients who had TUR-P due to BPH and were followed up for minimum 6 months, 51 patients detected to have urethral stricture based on endoscopic imaging were included in the urethral stricture group (Group 1) and 52 patients without urethral stricture were included in the control group (Group 2). The relation between histopathological findings of TURP materials and postoperative stricture occurrence was investigated. RESULTS: No difference in age, prostate volume, operation time and postoperative catheterization time was detected among the groups (p=0.86, p=0.13, p=0.06, p=0.32, respectively). Average time until the urethral stricture diagnosis in the group with urethral stricture was measured as 57.9±27.2 days. In our study, inflammation intensity in peri-urethral, stromal and periglandular areas and intraglandular destruction ratios were higher in urethral stricture group (Group 1) (p=0.048, p=0.3, p=0.03, p=0.01, respectively). Again, it was detected that neutrophil, plasmocyte and eosinophil cell ratios were higher in peri-urethral, stromal and periglandular areas and lymphocyte values were lower compared to the control group. CONCLUSION: Acquired data has shown that acute inflammatory attacks may be related to urethral stricture with a mostly chronic inflammation background in the prostate. During histopathological examination of prostate tissue acquired through TURP, especially high peri-urethral neutrophil, plasmocyte and eosinophil cell ratios and intra-glandular destruction ratios are important for predicting postoperative urethral stricture occurrences.

Role of poor urethral sphincter relaxation in men with voiding dysfunction refractory to α-blocker therapy: Clinical characteristics and predictive factors.

OBJECTIVES: This study evaluates the diagnostic value of poorly relaxed external sphincter (PRES) in men with voiding dysfunction. We analyzed clinical and video-urodynamic characteristics to identify predictive factors of PRES in patients with lower urinary tract symptoms (LUTS) refractory to α-1 adrenoceptor blocker (α-blocker) therapy. METHODS: This retrospective study included 3379 men with LUTS in whom the initial 1-month α-blocker therapy failed. Clinical parameters and video-urodynamic results were analyzed. Patients with bladder outlet disorders including bladder neck obstruction (BNO), benign prostatic obstruction (BPO), urethral stricture (US), or PRES were categorized according to video-urodynamic findings. Predictive factors for PRES were analyzed. RESULTS: A total of 3379 men were included in this study. Among the patients with voiding dysfunction, 905 (43.6%) had BPO, 624 (30.0%) had BNO, 487 (23.4%) had PRES, and 62 (3.0%) had US. Patients with PRES were younger and had a higher maximum flow rate, larger bladder capacity, smaller total prostate volume (TPV) and transition zone index, and a lower rate of LUTS of urgency or urge urinary incontinence (UUI) than other groups. On multivariate analysis, only small TPV and lower urgency/UUI rate were predictive factors of PRES. A scale composed of voided volume, TPV, and urgency/UUI predicted PRES with high specificity. CONCLUSIONS: PRES was the etiology of voiding dysfunction in 23.4% of the men with LUTS refractory to α-blocker therapy. A simple scale composed of voiding volume, TPV, and urgency/UUI was useful in predicting the presence of PRES before video-urodynamic studies.

Enucleation, Vaporization, and Resection: How To Choose the Best Surgical Treatment Option for a Patient with Male Lower Urinary Tract Symptoms.

Transurethral resection of the prostate remains the reference technique for patients with a prostate <100ml. Endoscopic enucleation is a safe and effective alternative, while photoselective vaporization of the prostate appears to be the treatment of choice for patients on anticoagulation medication.

Economic Value of the Transurethral Resection in Saline System for Treatment of Benign Prostatic Hyperplasia in England and Wales: Systematic Review, Meta-analysis, and Cost-Consequence Model.

CONTEXT: Monopolar transurethral resection of the prostate (M-TURP) is the current UK surgical standard of care for benign prostatic hyperplasia, a condition estimated to affect >2 million men in the United Kingdom. Although M-TURP efficacy in prostate resection is established, potential perioperative complications and associated costs remain a concern. OBJECTIVE: To present up-to-date and robust evidence in support of bipolar transurethral resection in saline (TURis) as an alternative surgical option to M-TURP. EVIDENCE ACQUISITION: A systematic review (SR) of electronic databases (up to 2015) for randomised controlled trials (RCTs) comparing TURis with M-TURP was conducted, followed by evidence synthesis in the form of a meta-analysis of hospital stay, catheterisation time and procedure duration, transurethral resection (TUR) syndrome, blood transfusion, clot retention, and urethral strictures. An economic analysis was subsequently undertaken from the UK National Health Service hospital perspective with costs and resource use data from published sources. EVIDENCE SYNTHESIS: The SR identified 15 good-quality RCTs, of which 11 were used to inform the meta-analysis. TURis was associated with improved safety versus M-TURP, eliminating the risk of TUR syndrome and reducing the risk of blood transfusion and clot retention (relative risks: 0.34 and 0.43, respectively; p<0.05). TURis also reduced hospital stay (mean difference: 0.56 d; p<0.0001). The economic analysis indicated potential cost savings with TURis versus M-TURP of up to £204 per patient, with incremental equipment costs offset by savings from reduced hospital stay and fewer complications. CONCLUSIONS: The TURis system is associated with significant improvements in perioperative safety compared with M-TURP while ensuring equivalent clinical outcomes of prostate resection. The safety benefits identified may translate into cost savings for UK health services. PATIENT SUMMARY: Our review of bipolar transurethral resection in saline, the new prostate resection technique, indicates that it offers equal efficacy while reducing complications and length of hospital stay.

Instrumentación transuretral en portadores de esfínter urinario artificial. Presentación y discusión de tres casos clínicos / Transurethral instrumentation in patients with artificial urinary sphincter. Presentation and discussion of three clinical cases

El tratamiento para la incontinencia urinaria masculina de esfuerzo severa es la colocación de un esfínter urinario artificial (EUA). La etiología de la incontinencia con frecuencia es la cirugía prostática previa. Los resultados funcionales son buenos con una tasa aceptable de complicaciones. Las complicaciones son más frecuentes si existe radioterapia previa o se realizan procedimientos transuretrales sin tener en cuenta la presencia del manguito del EUA. Cuando es necesaria la cirugía transuretral, por ejemplo por tumor vesical, es necesario realizar el desabrochado del manguito esfinteriano. Los sondajes uretrales precisan también desactivar el manguito y manipular la uretra con sumo cuidado, evitando su manipulación siempre que sea posible. Se presentan tres casos muy complejos de pacientes portadores de EUA que han precisado diversas soluciones ante manipulación uretral y presencia de complicaciones como estenosis de uretra (AU)

Artificial urinary sphincter (AS) is the gold standard treatment for severe male urinary stress incontinence. The etiology of incontinence is often previous prostate surgery as a radical prostatectomy. Functional results are good with an acceptable rate of complications. If there is prior radiotherapy complications are more frequent. When transurethral surgery, for example for bladder tumor is needed, it is necessary unbuttoned the sleeve. Urethral soundings need also turn off the sleeve and manipulate the urethra carefully, avoiding handling whenever possible. We present three very complex cases of patients with US showing several solutions to urethral manipulation and to resolve complications such as urethral perforation and stricture (AU)

[Treatment of the urethral sphincter insufficiency]. / Prise en charge de l'insuffisance sphinctérienne urétrale.

The intrinsic sphincter insufficiency is a cause of stress urinary incontinence. Its definition is clinical and based on urodynamics. It is mostly met with women, in context of the post-obstetrical period or older women in a multifactorial context. For men, it occurs mainly as complication of the surgery of the cancer of prostate or bladder. An initial, clinical and paraclinical assessment allows to confirm the diagnosis of intrinsic sphincter insufficiency, to estimate its severity, and to identify associated mechanisms of incontinence (urethral hypermobility, bladder overactivity) to choose the most adapted treatment. The perineal reeducation is the treatment of first intention in both sexes. At the menopausal woman, the local hormonotherapy is a useful additive. In case of failure or of incomplete efficiency, the treatment of the intrinsic sphincter insufficiency is surgical. Bulking agents, urethral slings, peri-urethral balloons and artificial sphincter are 4 therapeutic options to discuss according to history, the severity of the incontinence, the expectations of the patient.

Midterm results from an international multicentre randomised controlled trial comparing bipolar with monopolar transurethral resection of the prostate.

BACKGROUND: Pooled data from randomised controlled trials (RCTs) with short-term follow-up have shown a safety advantage for bipolar transurethral resection of the prostate (B-TURP) compared with monopolar TURP (M-TURP). However, RCTs with follow-up >12 mo are scarce. OBJECTIVE: To compare the midterm safety/efficacy of B-TURP versus M-TURP. DESIGN, SETTING, AND PARTICIPANTS: From July 2006 to June 2009, TURP candidates with benign prostatic obstruction were consecutively recruited in four centres, randomised 1:1 into the M-TURP or the B-TURP arm and regularly followed up to 36 mo postoperatively. A total of 295 patients were enrolled. INTERVENTION: M-TURP or B-TURP using the AUTOCON II 400 electrosurgical unit. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Safety was estimated by complication rates with a special emphasis on urethral strictures (US) and bladder neck contractures (BNCs) recorded during the short-term (up to 12 mo) and midterm (up to 36 mo) follow-up. Efficacy quantified by changes in maximum urine flow rate, postvoid residual urine volume, and International Prostate Symptom Score was compared with baseline, and reintervention rates in each arm were also evaluated. RESULTS AND LIMITATIONS: A total of 279 patients received treatment after allocation. Mean follow-up was 28.8 mo. A total of 186 of 279 patients (66.7%) completed the 36-mo follow-up. Posttreatment withdrawal rates did not differ significantly between arms. Safety was assessed in 230 patients (82.4%) at a mean follow-up of 33.4 mo. Ten US cases were seen in each arm (M-TURP vs B-TURP: 9.3% vs 8.2%; p=0.959); two versus eight BNC cases (M-TURP vs B-TURP: 1.9% vs 6.6%; p=0.108) were collectively detected at the midterm follow-up. Resection type was not a significant predictor of the risk of US/BNC formation. Efficacy was similar between arms and durable. A total of 10 of 230 patients (4.3%) experienced failure to cure and needed reintervention without significant differences between arms. High overall reintervention rates, withdrawal rates, and sample size determination not based on US/BNC rates represent potential limitations. CONCLUSIONS: The midterm safety and efficacy of B-TURP and M-TURP are comparable. TRIAL REGISTRATION: Netherlands Trial Register, NTR703 (http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=703).

[Simultaneous treatment for benign prostate hyperplasia and its concomitant diseases].

OBJECTIVE: To investigate the surgical treatment of benign prostate hyperplasia (BPH) and its concomitant diseases at the same time. METHODS: One hundred and fourteen operations were performed for BPH patients, including transurethral resection/vapor of the prostate (TURP/TUVP), inguinal herniorrhaphy, internal urethrotomy, transurethral resection of bladder tumor (TURBt) or vesical litholapaxy, and the data were reviewed. RESULTS: The procedures were successful in all cases. A follow-up of 3 to 60 months found a good outcome of TURP. There was no recurrence in 30 cases of inguinal hernia and 39 cases of vesical calculus. Of the 25 cases of urethral stricture, 1 had an obvious hypotension during the operation and 4 needed urethral dilatation after operation. Six of the 20 cases of bladder tumor underwent a second TURBt due to the recurring tumor which was far from prostatic urethra. CONCLUSION: Inguinal hernia, urethral stricture, bladder tumor or vesical calculus can be treated simultaneously during TURP.

Prolapso de uretra / Urethral prolapse

El prolapso uretral en la mujer es infrecuente. Se define como la completa eversión de la mucosa uretral a través del meato. Ocurre frecuentemente en mujeres negras prepúperes y en mujeres blancas posmenopáusicas. El tratamiento recomendado incluye desde la terapia conservadora hasta múltiples intervenciones quirúrgicas (AU)

Prolapse of the urethra in female patients is a rare events. It is defined as the complete eversion of the urethral mucosa through the external meatus. It occurs most often in pre-puberal black girls and in postmenopausal white women. Recommended treatment ranges from conservative therapy to a diversity of operative techniques (AU)

[A case report: an urethral tumor with cavernous structure developed after optical urethrotomy].

A 70-year-old man underwent transurethral resection of the prostate (TURP) in February 1999 and he received optical urethrotomy because of urethral stricture in May. In May 2000, a distal urethral tumor was found by urethroscopy. Endoscopic resection of the urethral tumor was performed. The tumor consisted of normal urethral epithelial tissue and had a cavernous structure. We conclude that the tumor was vegetation of the corpus spongiosum penis.

[Endoscopic treatment of complete obliteration of posterior urethra]. / Endoskopsko lechenie na p'lnata obliteratsiia na zadnata uretra.

The authors shared their experience in regard of treatment of complete urethral obliteration. In a 14-year they diagnosed and treated 37 patients (aged 22-74 years) with obstruction of the lower urinary tract as a result of complete urethral obliteration. The etiology include 14 patients after perineal urethral trauma, in 10 patients the main cause was urethral inflammation of posterior urethra, in 8--as a consequence of transurethal surgery and in 5--after suprapubic prostatectomy. Main diagnostic methods they used were retrograde urethrography and urethroscopy with 0. fiberoptic. In all patients an endoscopic incision of fibrotic tissue was carried out thus the entering the bladder cavity was successful. In some patients operative technique with a Benique through cystostomy cannel and bladder neck just opposite to the urethrotome knife was used. In three patients (8.2%) the procedure failed due to the massive urethral hemorrhage. They report recurrent urethral strictures in 24 patients (64.8%), treated with visual urethrotomy. The continence was compromised in 6 patients (16.2%).

[The blood antioxidant system under the influence of biocontrolled laser and antioxidant therapy in patients with urethral strictures]. / Antioksidantnaia sistema krovi pod vliianiem bioupravliaemoi lazernoi i antioksidantnoi terapii u bol'nykh so strikturami uretry.

Superoxide dismutase activity in blood red cells of patients with urethral strictures reflects the disease severity and the response to relevant treatment. Antioxidant therapy with dibunol on the first postoperative days, administration of vitamin E before and after the operation and laser biocontrolled chronotherapy for 2 weeks before and after the operation with repetition in 1-2 months are recommended in addition to conventional treatment to reduce probability of complications and recurrences after surgical treatment of urethral strictures.

[Gangrene of the external genital organs. Apropos of 55 cases]. / La gangrène des organes génitaux externes. A propos de 55 cas.

Gangrène of the male external genitalia (GMEG) is characterized by necrotizing cell evolving toward necrotizing of the soft tissues of the male genitalia and possibly death. The cause may be primary infection called Fournier's gangrene (5%) or secondary infection (95%) due to general or local factors. GMEG is a real urinary emergency because of its local and general complications which lead to death in 20% of cases. Precocious and massive antibiotherapy, a surgery to unbridle and possibly reanimation, oxygenotherapy, urinary diversion or colostomy, are required. We have treated 55 men with this affection from january 1988 to may 1996. Mean age was 58 years (range 20 to 85). The prodromial period was about 12 days. Toxi-infectious shock was noted in 8 patients (14%). Six patients (10%) developed renal acute insufficiency. Lesions were localized to the male external genitalia in 24 cases and stretched to the inguinalis, to the abdomen or to the thorax in 34 patients. The cause was a stricture of urethra in 23 cases (41%) diabetes in 18 cases (32%), anal abscess in 7 cases (13%). No etiology was found in 6 cases (10%). Emergency treatment involved three antibiotics, surgery to unbridle necrotizing tissue in all patients, reanimation in 20 patients (35%), oxygenotherapy in 4 patients (7%), colostomy in 2 cases and urinary drainage in 23 patients (42%). Free skins grafts were necessary in 6 patients (10%), 5 patients (9%) died due to septic shock. On the basis of these observations and a review of the literature, we analyzed the ethiopathogenic, bacteriological and therapeutic aspects of this affection marked by high mortality in spite of therapeutic progress.

Urethral narrowing and its treatment: a possible solution for the problems of recurrent urinary infection and the "irritable bladder".

A surgical treatment for longstanding urinary and pelvic complaints of women is described and evaluated. The procedure includes urethral dilatation to 40 F and "snowplowing" (dull curettage) of urethral, bladder neck, and trigonal mucosa with the heel of the cystoscope, removing granulated tissue, polyps, and villous fronds, and unroofing infected periurethral glands. Vigorous urethral massage is performed, and the patient is hospitalized overnight with large-catheter drainage to continue dilatation. Follow-up dilatations in the office are essential. The procedure was evaluated by comparing presenting and post-treatment symptoms for each patient and by asking each patient to rate the effectiveness of the treatment. Results suggest that treatment is very effective, with 80 per cent of respondents rating it either excellent or good.

The prophylaxis of nonindustrial urothelial tumours.

Present knowledge concerning carcinogenesis and the natural history of urothelial tumours precludes firm conclusions relative to nonindustrial prophylaxis. However, a number of measures are consistent with current data and may be instituted for those patients with a demonstrated propensity to urothelial tumours. Their acceptability is based on the lack of associated toxicity for the patient. These measures include the elimination of significant infection, cigarettes, artificial sweeteners, analgesic abuse and coffee, the administration of vitamins C and B(6), and in selected cases, the use of thiotepa. It is emphasized that the merit of these steps in altering the natural history of urothelial tumours is uncertain.
