RESUMEN
OBJECTIVE: To investigate the clinical effect of pulsed thulium laser (PTL) combined with triamcinolone acetonide injection in the treatment of failed posterior urethral anastomosis (FPUA). METHODS: This retrospective study included 35 male patients treated in Gongli Hospital for failed posterior urethral anastomosis from January 2018 to December 2023. All the patients underwent direct-vision internal urethrotomy (DVIU) with transurethral PTL (the PTL group, n = 15) or transurethral plasma (the TUP group, n = 20), and all received intralesional injection of triamcinolone acetonide. We followed up the patients for a median of 21 months, recorded the age, length of urethral stricture, operation time, pre- and post-operative maximum urinary flow rate (Qmax), postoperative complications and recurrence of urethral stricture, and compared the data obtained between the two groups. RESULTS: All the patients smoothly completed the treatment procedures. No statistically significant differences were observed in the age, length of urethral stricture, operation time and postoperative complications between the two groups (P > 0.05). The median follow-up time for the thulium laser group and plasma group was 21.0 months (IQR 16.0ï¼24.0) and 21.0 months (IQR 17.0ï¼25.0), respectively, with a statistically significant difference observed in the maximum urine flow rate before and after surgery at the 12-month mark (P < 0.01). No significant disparity was found in terms of relapse-free survival between the two groups (P = 0.398) Conclusion: Pulsed thulium laser combined with triamcinolone acetonide injection can effectively maintain a short-term cicatricial stability of the urethral stricture and satisfactory urethral patency, obviously superior to plasmotomy as a remedial treatment of urethral stricture after failed posterior urethral anastomosis.

OBJECTIVE: To investigate the clinical efficacy of electrophysiological appropriateness technique (EAT) therapy based on the traditional Chinese medicine (TCM) meridian theory in managing postoperative pain after urethral reconstruction surgery. METHODS: Using the real-world study approach, we enrolled 61 male patients undergoing urethral reconstruction and divided them into a control group (n = 30) and an observation group (n = 31), the former receiving patient-controlled intravenous analgesia (PCIA), while the latter PCIA plus EAT at 4 pairs of acupoints (Hegu, Neiguan, Zusanli and Sanyinjiao bilaterally) and the Ashi point, with 100 mg tramadol hydrochloride given orally as remedial analgesia in both groups in case of postoperative Visual Analogue Scale (VAS) score ≥4. We compared the VAS scores at 4, 12, 24 and 48 hours postoperatively, the dose of cumulative fentanyl used at 48 hours, the number of cases needing remedial analgesia, the time to first flatus and the incidence of adverse reactions between the two groups of patients. RESULTS: The VAS scores were markedly lower in the observation than in the control group at 4, 12, 24 and 48 hours after surgery (P < 0.05), with statistically significant differences in time-dependent effect and interactive effect (P < 0.05). Significant reduction was observed in the doses of cumulative fentanyl (P < 0.05) and remedial tramadol analgesia (P < 0.05), time to first flatus (P < 0.05), and incidence of adverse reactions (P < 0.05) in the observation group in comparison with the controls. CONCLUSION: Electrophysiological therapy based on the TCM meridian theory can safely and effectively alleviate postoperative pain after urethral reconstruction, reduce opioid consumption, and decrease adverse events.

Long-segment lichen sclerosus (LS) urethral stricture is a challenge for urologists. Limited data are available for surgeons to make a surgical decision between Kulkarni and Asopa urethroplasty. In this retrospective study, we investigated the outcomes of these two procedures in patients with LS urethral stricture. Between January 2015 and December 2020, 77 patients with LS urethral stricture underwent Kulkarni and Asopa procedures for urethroplasty in the Department of Urology, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine (Shanghai, China). Of the 77 patients, 42 (54.5%) underwent the Asopa procedure and 35 (45.5%) underwent the Kulkarni procedure. The overall complication rate was 34.2% in the Kulkarni group and 19.0% in the Asopa group, and no difference was observed ( P = 0.105). Among the complications, no statistical difference was observed in the incidence of urethral stricture recurrence ( P = 0.724) or glans dehiscence ( P = 0.246) except for postoperative meatus stenosis ( P = 0.020). However, the recurrence-free survival rate between the two procedures was significantly different ( P = 0.016). Cox survival analysis showed that antiplatelet/anticoagulant therapy use ( P = 0.020), diabetes ( P = 0.003), current/former smoking ( P = 0.019), coronary heart disease ( P < 0.001), and stricture length ( P = 0.028) may lead to a higher hazard ratio of complications. Even so, these two techniques can still provide acceptable results with their own advantages in the surgical treatment of LS urethral strictures. The surgical alternative should be considered comprehensively according to the patient characteristics and surgeon preferences. Moreover, our results showed that antiplatelet/anticoagulant therapy use, diabetes, coronary heart disease, current/former smoking, and stricture length may be contributing factors of complications. Therefore, patients with LS are advised to undergo early interventions for better therapeutic effects.

OBJECTIVE: The aim of this study was to describe the clinical and procedural risk factors associated with the unplanned neurosurgical intensive care unit (NICU) readmission of patients after elective supratentorial brain tumor resection and serves as an exploratory analysis toward the development of a risk stratification tool that may be prospectively applied to this patient population. METHODS: This was a retrospective observational cohort study. The electronic medical records of patients admitted to an institutional NICU between September 2018 and November 2021 after elective supratentorial brain tumor resection were reviewed. Demographic and perioperative clinical factors were recorded. A prognostic model was derived from the data of 4892 patients recruited between September 2018 and May 2021 (development cohort). A nomogram was created to display these predictor variables and their corresponding points and risks of readmission. External validation was evaluated using a series of 1118 patients recruited between June 2021 and November 2021 (validation cohort). Finally, a decision curve analysis was performed to determine the clinical usefulness of the prognostic model. RESULTS: Of the 4892 patients in the development cohort, 220 (4.5%) had an unplanned NICU readmission. Older age, lesion type, Karnofsky Performance Status (KPS) < 70 at admission, longer duration of surgery, retention of endotracheal intubation on NICU entry, and longer NICU length of stay (LOS) after surgery were independently associated with an unplanned NICU readmission. A total of 1118 patients recruited between June 2021 and November 2021 were included for external validation, and the model's discrimination remained acceptable (C-statistic = 0.744, 95% CI 0.675-0.814). The decision curve analysis for the prognostic model in the development and validation cohorts showed that at a threshold probability between 0.05 and 0.8, the prognostic model showed a positive net benefit. CONCLUSIONS: A predictive model that included age, lesion type, KPS < 70 at admission, duration of surgery, retention of endotracheal intubation on NICU entry, and NICU LOS after surgery had an acceptable ability to identify elective supratentorial brain tumor resection patients at high risk for an unplanned NICU readmission. These risk factors and this prediction model may facilitate better resource allocation in the NICU and improve patient outcomes.
RESUMEN
BACKGROUND: Decompressive craniectomy (DC) and intracranial pressure (ICP) monitoring are common approaches to reduce the death rate of Traumatic brain injury (TBI) patients, but the outcomes of these patients are unfavorable, particularly those who receive bilateral DC. The authors discuss their experience using ICP and other potential methods to improve the outcomes of TBI patients who receive bilateral DC. METHODS: Data from TBI patients receiving bilateral DC from Jan. 2008 to Jan. 2022 were collected via a retrospective chart review. Included patients who received unplanned contralateral DC after initial surgery were identified as unplanned secondary surgery (USS) patients. Patients' demographics and baseline medical status; pre-, intra-, and postoperative events; and follow-up visit outcome data were analyzed. RESULTS: A total of 151 TBI patients were included. Patients who underwent USS experienced more severe outcomes as assessed using the 3-month modified Rankin Scale score (P = 0.024). In bilateral DC TBI patients, USS were associated with worsen outcomes, moreover, ICP monitoring was able to lower their death rate and was associated with a lower USS incidence. In USS patients, ICP monitoring was not associated with improved outcomes but was able to lower their mortality rate (2/19, 10.5%, vs. 10/25, 40.0%; P = 0.042). CONCLUSION: The avoidance of USS may be associated with improved outcomes of TBI patients who underwent bilateral DC. ICP monitoring was a potential approach to lower USS rate in TBI patients, but its specific benefits were uncertain.

Artificial urethral sphincter (AUS) implantation is the definitive management of male stress urinary incontinence (SUI). Under the long-term pressure of the cuff, recurrence of incontinence caused by urethral atrophy can always be observed in patients. In this situation, distal cuff locations are needed, and new cuff sites should be sought in patients who need to undergo AUS reimplantations. Meanwhile, the circumference of the more distal urethra is often too small to fit with a 4.0 cm cuff. This means that the bulk of the urethra should be added not only for a sufficient urethral circumference but also for better protection. Here, we report a case that required AUS reimplantation because of urethral atrophy. This 73-year-old man had undergone AUS implantation 7 years ago and developed incontinence in the past 3 months. Physical examination and ultrasonography determined that the device still worked, and no obstruction or injury was observed through cystoscopy. Surgery for revision of the AUS was needed. In this operation, a new cuff was implanted transcorporally, which was 2 to 3 cm distal to the original cuff site. During a 6 month short-term follow-up, no stress incontinence, urethral injury, or dysuria was observed. The transcorporal technique offers significant advantages in patients with urethral atrophy: corporal tunica albuginea is added to the urethra, allowing a suitable cuff size and lower risk of erosion. It is worth recommending in the reoperation of AUS implantation.

Background: This study describes and compares three surgical procedures for the construction of urethral stricture (US) models in rabbits. Methods: Forty adult male rabbits were allocated to four groups: 36 rabbits were randomly assigned to three experimental groups, while the remaining 4 were assigned to a sham group. The penis was separated from the rectum. Then along the ventral midline, a longitudinal penile skin incision was made while ensuring that the urethral mucosa was intact and the muscular layer was not completely incised. In group 1 (n=12), ventral semi-circumferential mucosa electrocoagulation of a 1-cm length of the anterior urethra was performed until ulceration occurred. In group 2 (n=12), the ventral urethral mucosa was incised, and electrocoagulation of the dorsal semi-circumferential mucosa was performed. In group 3 (n=12), whole-circumferential mucosa electrocoagulation was performed. In group 4 (n=4), no special treatment was performed. Four weeks later, urethrography, urethroscopy, and histological evaluation were carried out. Results: The weights of the rabbits in the four groups were comparable. There was no significant difference between groups 2 and 3 with regard to operative time, but the operative time in these groups was significantly longer than that in group 1 (group 2 vs. group 1: P<0.05, group 3 vs. group 1: P<0.001). After the surgery, urinary fistula with infection occurred in one rabbit in group 1, and one rabbit died due to urethral atresia in group 3. According to the urethrography and urethroscopy findings, 9 out of 12 rabbits in group 1, 5 out of 12 rabbits in group 2, and 11 out of 11 rabbits in group 3 developed US, while no rabbits in the sham group developed US. Histopathological examination revealed injury to the urothelium, inflammatory infiltration, a decrease in the amount of blood vessels and smooth muscle fibers, and a decrease in the amount of collagen fibers. Conclusions: Compared with the semi-circumferential procedures, the whole-circumferential procedure had a higher success rate. Therefore, this procedure seems to have potential for the construction of long-segment rabbit US models.
RESUMEN
BACKGROUND: Our aim of this study was to identify risk factors and develop a prediction model for unplanned neurological intensive care unit (NICU) events after elective infratentorial brain tumor resection in order to propose an individualized admission to the NICU tailored to patient needs. METHODS: Patients admitted to our NICU between September 2018 and May 2021 after elective infratentorial brain tumor resection were reviewed. Prolonged NICU stays and unplanned NICU admissions were defined as unplanned NICU events. The prognostic model of unplanned NICU events was developed using a forward stepwise logistic regression analysis, and external validation was evaluated. The C-statistic was used to assess discrimination, and a smooth, nonparametric calibration line was used to assess calibration graphically in the model. RESULTS: Of the 1,710 patients in the development cohort, unplanned NICU events occurred in 162 (9.5%). Based on the lesion type, a Karnofsky Performance Status score <70 at admission, longer duration of surgery, bleeding in the operative area evident on postoperative computed tomography, higher fibrinogen and blood glucose levels at admission, and more intraoperative blood loss were independently associated with unplanned NICU events. The external validation test showed good discrimination (C-statistic = 0.811) and calibration (Hosmer-Lemeshow P = 0.141) for unplanned NICU events. CONCLUSIONS: Several patient and operative characteristics are associated with a greater likelihood of the occurrence of unplanned NICU events. In the future, we may be able to provide better help for the resource allocation of NICUs according to these risk factors and prediction models.

BACKGROUND: Extramammary Paget's disease (EMPD) is a rare malignant intraepidermal adenocarcinoma that is poorly understood. Regulatory long noncoding RNAs (lncRNAs) are characterized in many species and shown to be involved in processes such as development and pathologies, revealing a new layer of regulation in different diseases, especially in cancer studies. In the present study, we used high-throughput sequencing to reveal the lncRNA-mRNA interaction network in extramammary Paget's disease. METHODS: High-throughput sequencing was used to identify differentially expressed lncRNA and mRNA profiles between EMPD patients and healthy controls. Then, a series of bioinformatics analyses were conducted to construct the lncRNA-mRNA interaction network, which was finally confirmed in vitro. RESULTS: Six pairs of EMPD tumor and normal skin samples were collected and sequenced to identify the differentially expressed lncRNA and mRNA profiles between EMPD and healthy controls. A total of 997 differentially expressed mRNAs and 785 differentially expressed lncRNAs were identified. The GO and KEGG analyses show that epidermal development and cell adhesion play important roles in EMPD. The results of the lncRNA-mRNA interaction network analysis suggested that NEAT1, PGAP1, FKBP5 and CDON were the pivotal nodes of the network and that lncRNA NEAT1 might regulate mRNA PGAP1, FKBP5 and CDON. The results of the quantitative real-time RT-PCR performed in ten other patients for NEAT1, PGAP1, FKBP5 and CDON were consistent with those of the sequencing analysis. Moreover, an in vitro experiment confirmed the interactions between NEAT1 and PGAP1, FKBP5 and CDON in human immortalized keratinocytes. CONCLUSION: These findings suggest that the lncRNA-mRNA interaction network based on four pivotal nodes, NEAT1, PGAP1 FKBP5 and CDON, may play an important role in EMPD, which will contribute to a deeper understanding of the pathogenesis of EMPD.

RATIONALE: Tissue engineering is a promising alternative for urethral reconstruction, and adipose-derived stem cells (ADSCs) are widely used as seeding cells. Hypoxia preconditioning can significantly enhance the therapeutic effects of ADSCs. The low oxygen tension of postoperative wound healing is inevitable and may facilitate the nutritional function of ADSCs. This study aimed to investigate if hypoxia-preconditioned ADSCs, compared to normoxia-preconditioned ADSCs, combined with scaffold could better promote urethral reconstruction and exploring the underlying mechanism. METHODS: In vitro, paracrine cytokines and secretomes that were secreted by hypoxia- or normoxia-preconditioned ADSCs were added to cultures of human umbilical vein endothelial cells (HUVECs) to measure their functions. In vivo, hypoxia- or normoxia-preconditioned ADSCs were seeded on a porous nanofibrous scaffold for urethral repair on a defect model in rabbits. RESULTS: The in vitro results showed that hypoxia could enhance the secretion of VEGFA by ADSCs, and hypoxia-preconditioned ADSCs could enhance the viability, proliferation, migration, angiogenesis, and glycolysis of HUVECs (p < 0.05). After silencing VEGFA, angiogenesis and glycolysis were significantly inhibited (p < 0.05). The in vivo results showed that compared to normoxia-preconditioned ADSCs, hypoxia-preconditioned ADSCs combined with scaffolds led to a larger urethral lumen diameter, preserved urethral morphology, and enhanced angiogenesis (p < 0.05). CONCLUSIONS: Hypoxia preconditioning of ADSCs combined with scaffold could better promote urethral reconstruction by upregulating angiogenesis and glycolysis. Hypoxia-preconditioned ADSCs combined with novel scaffold may provide a promising alternative treatment for urethral reconstruction.

BACKGROUND: Male genital skin loss is a common disease in urology. However, male genital skin loss accompanying a penile urethra defect is rarely reported. Herein, we describe a novel surgical technique using a composite local flap and oral mucosal graft to reconstruct the penis, which may provide a new solution for patients with similar conditions. CASE PRESENTATION: A 36-year-old male with a penile urethra defect and a large area of genital skin loss required urethral reconstruction. The meatus had descended to the penoscrotal junction. This procedure was divided into three stages. The first stage of the surgery involved burying the nude penile shaft beneath the skin of the left anteromedial thigh for coverage of the skin defect. The second stage consisted of releasing the penis and expanding the size of the urethral plate for further urethroplasty. The third stage consisted of reconstruction of the anterior urethra 6 months later. Postoperatively, the patient reported satisfactory voiding. The maximal flow rate (MFR) was 22.2 ml/s with no postvoiding residual urine at the 24-month follow-up visit. No edema, infection, hemorrhage, or cicatricial retraction were observed. The patient's erectile function was satisfactory, and his international index of erectile function-5 score (IIEF-5 score) was 23 at the 24-month follow-up visit. Additionally, the presence of nocturnal penile tumescence demonstrated that he had normal erectile function. CONCLUSIONS: This procedure is an effective surgical option for men with complete foreskin and penile urethra defects. It could also be extended as a treatment strategy when composite local or pedicle transposition flaps and free grafts are needed for specific patients.

In this study, we investigated the genetics, clinical features, and therapeutic approach of 14 patients with 5α-reductase deficiency in China. Genotyping analysis was performed by direct sequencing of PCR products of the steroid 5α-reductase type 2 gene (SRD5A2). The 5α-reductase activities of three novel mutations were investigated by mutagenesis and an in vitro transfection assay. Most patients presented with a microphallus, variable degrees of hypospadias, and cryptorchidism. Eight of 14 patients (57.1%) were initially reared as females and changed their social gender from female to male after puberty. Nine mutations were identified in the 14 patients. p.G203S, p.Q6X, and p.R227Q were the most prevalent mutations. Three mutations (p.K35N, p.H162P, and p.Y136X) have not been reported previously. The nonsense mutation p.Y136X abolished enzymatic activity, whereas p.K35N and p.H162P retained partial enzymatic activity. Topical administration of dihydrotestosterone during infancy or early childhood combined with hypospadia repair surgery had good therapeutic results. In conclusion, we expand the mutation profile of SRD5A2 in the Chinese population. A rational clinical approach to this disorder requires early and accurate diagnosis, especially genetic diagnosis.

INTRODUCTION: To present 12 cases of arterial priapism treated by superselective embolization and propose our management algorithm for this condition. METHODS: Between February 2013 and May 2018, 12 cases of arterial priapism caused by blunt trauma were treated by superselective embolization. The mean age of patients was 36 years (25-47 years). All of the patients had normal sexual capability before priapism (IIEF-5 scores 24-25). All patients were treated with superselective embolization after more than 3 weeks of simple conservative treatment had failed. All cases but one used a gelatin sponge as embolic agent. A microcoil was added in one case in which the gelatin sponge failed to occlude the pseudoaneurysm. After superselective embolization, ice pack and "observation" treatments continued. The sexual capability of the patients was evaluated by IIEF-5 scores at 6 months and 12 months postoperatively. RESULTS: The mean follow-up period was 27.2 months (13-48 months). Three patients achieved complete detumescence immediately. Nine cases needed 2-17 days to return to a flaccid nonpainful state. No patient underwent a second embolization. The time needed to improve erectile function was from 7 days to 4 months. There has been no recurrence. Eleven patients treated with gelatin sponge have normal erectile function, while one patient treated with additional microcoil embolization had mild erectile dysfunction. CONCLUSION: Superselective embolization of the fistula is an effective option for arterial priapism. Absorbable agents should be used. Superselective arterial embolization should be considered after 3 weeks of conservative treatment. Patients should undergo another 3 weeks of "observation" treatment before repeated intervention.

OBJECTIVE: To investigate the clinical features, pathogenesis, diagnosis and scrotal reconstruction in the treatment of idiopathic scrotal calcinosis (ISC). METHODS: From March 2007 to October 2018, 10 ISC patients, aged 28ï¼79 (mean 45) years and with a disease course of 6ï¼497 (mean 128.4) months, were treated in our hospital. We retrospectively analyzed their clinical data and reviewed related literature. RESULTS: All the patients underwent physical examination and biochemical and parathyroid function tests. None of them had a history of endocrine or metabolic disease, or trauma, or a family member with similar diseases, and none had subjective symptoms except local pruritus in 1 case. All were treated surgically and post-operative follow-up revealed no recurrence. Histopathological examination of the excised lesion confirmed it to be ISC. CONCLUSIONS: ISC is a rare localized benign disease, of which surgery seems an effective option for the definite diagnosis and treatment. Occasionally scrotal reconstruction may be required in case of extensive involvement of the scrotal skin.

OBJECTIVE: To investigate the diagnosis and management of penile fracture. METHODS: From June 1993 to May 2017, 46 cases of penile fracture were treated in our hospital, averaging 33.5 (25ï¼42) years of age and 3.45 (1ï¼10) hours in duration, of which 41 occurred during sexual intercourse, 4 during masturbation and 1 during prone sleeping, 4 with hematuria, but none with dysuria or urethral bleeding. Hematoma was confined to the penis. Emergency surgical repair was performed for all the patients, 45 under spinal anesthesia and 1 under local anesthesia, 16 by coronal proximal circular incision and the other 30 by local longitudinal incision according to the rupture location on ultrasonogram. The tunica albuginea ruptures averaged 1.31 (0.5ï¼2.5) cm in length, which were sutured in the "8" pattern for 6 cases and with the 3ï¼0 absorbable thread for 18 cases. The skin graft or negative pressure drainage tube was routinely placed, catheters indwelt, and gauze used for early pressure dressing. In the recent few years, elastic bandages were employed for 3ï¼5 days of pressure dressing and antibiotics administered to prevent infection. The stitches and catheter were removed at 7 days after surgery. RESULTS: Short-term postoperative foreskin edema occurred in 14 of the 16 cases of circular degloving incision, but no postoperative complications were observed in any of the cases of local incision. Twenty-eight of the patients completed a long-term follow-up of 49.4 (10ï¼125) months, which revealed good erectile function, painless erection, and satisfactory sexual intercourse. CONCLUSIONS: For most penile fractures, local longitudinal incision is sufficient for successful repair of the tunica albuginea, with mild injury, no influence on the blood supply or lymph reflux, and a low rate complications. It therefore is obviously advantageous over circular degloving incision except when the cavernous body of urethra is to be explored, which necessitates circular degloving incision below the coronal groove.

OBJECTIVE: To introduce our experience in the treatment of arterial priapism by superselective embolization. METHODS: This study included 5 cases of perineal trauma-induced arterial erectile dysfunction treated in our departmentbetween February 2011 and May 2015, all failingpreviously to respond to 3 weeks of conservative treatment. The patients were aged 25ï¼47 (mean 35) years, with the onset of arterial priapism at 2ï¼5 days after trauma, and all subjected to physical examination, blood gas analysis, color Doppler ultrasonography of the corpora cavernosum, and IIEF-5 scoring. All the patients underwent superselective embolization, followed by local pressing and cold compression, and IIEF-5 scores were obtained again at 6 and 12 months postoperatively. RESULTS: All the patients had normal erectile functionbefore trauma, with a mean IIEF-5 scoreof 24.60 ± 0.55. Complete detumescenceor painless flaccidity of the penis was achieved in 1 case immediately after surgery and in the other 4 after 3ï¼17 days of postoperative conservative treatment. None of the patients needed a second embolization and no relapse was found during a mean follow-upof 27.2 (13ï¼48)months. The IIEF-5 scores obtained at 6 (24.00 ± 1.02) and 12 months (24.20 ± 0.82) were normal, with no statistically significant differencesfrom that before trauma. CONCLUSIONS: Selective embolization is a safe and effective option for the treatment of arterial priapism. In case of no immediate painless flaccidity of the penis after surgery, conservative treatment can be extended rather than a second operation.

INTRODUCTION: Till date, there have been few reports of comparative studies on the outcomes of these different treatment modalities. In this study, we have aimed to comparatively evaluate the quality-of-life parameters, including sexual function, urinary function, and health-related quality of life (HRQOL), in patients with early stage penile cancers who underwent two different organ-sparing surgeries. MATERIAL AND METHODS: From March 2012 to March 2015, we enrolled 15 patients with early stage penile cancers who underwent either wide local excision or partial penectomy as organ-sparing surgical treatments. We assessed their sexual and urinary functions and their HRQOL, using the International Index of Erectile Function (IIEF-15), Self-Esteem and Relationship (SEAR), and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaires and urodynamic determinations, and comparatively analyzed the outcomes of these patients who underwent either type of surgery. RESULTS: All patients who underwent these two types of surgeries experienced satisfactory outcomes. The patients who underwent wide local excision performed relatively better, in terms of their sexual functions, urinary functions, and HRQOL, but no statistically significant differences were observed in the data collected via the IIEF-15, SEAR, EDITS, and EORTC-QLQ-C30 questionnaires and urodynamic determinations (p > 0.05), except in the data corresponding to the orgasmic function (p = 0.033). CONCLUSION: Both types of organ-sparing surgeries assessed in this study achieved good outcomes, in terms of the aesthetics, sexual functions, urinary functions, and HRQOL in patients, without compromising the therapeutic effects of these surgeries. However, the observed decreases in orgasmic function will need to be addressed further.

OBJECTIVE: To evaluate the clinical effect of modified transobturator bulbourethral sling suspension (TBSS) in the treatment of stress urinary incontinence following radical prostatectomy. METHODS: Seven male patients with stress urinary incontinence after radical prostatectomy were treated by modified TBSS in our hospital from June 2015 to June 2017 and the clinical data were analyzed retrospectively. RESULTS: The mean operation time of the 7 cases was 60ï¼80 minutes and the mean intra-operative blood loss was 20ï¼40 m1. The catheter was removed on the first day after surgery, and all the incisions were healed in stage â . During a follow-up of 6ï¼18 months, all the 7 cases were found cured, with transient acute urinary retention in 1 case and short-term perineal pain in another as post-operative complications. At 6 months after surgery, urodynamic examinations showed no statistically significant differences from the baseline in the maximum urinary flow rate (ï¼»15.0 ± 1.6ï¼½ vs ï¼»13.7 ± 2.1ï¼½ ml/s, P > 0.05), urine output volume (ï¼»318.6 ± 52.1ï¼½ vs ï¼»298.6 ± 36.3ï¼½ ml, P > 0.05), and postvoid residual urine volume (ï¼»11.4 ± 9.4ï¼½ vs ï¼»7.1 ± 5.7ï¼½ ml, P > 0.05). CONCLUSIONS: Modified TBSS, with the advantages of less invasiveness, few complications, and low cost, is an effective option for the treatment of stress urinary incontinence after radical prostatectomy.

PURPOSE: To evaluate the therapeutic effect of surgery in patients with advanced penile cancer, who have a dismal prognosis. PATIENTS AND METHODS: Between September 2007 and July 2015, we treated 12 patients with surgical therapy. RESULTS: The median follow-up period for all the patients was 16 months (range 4-60 months). The outcome and concomitant symptoms were analyzed, and the survival rates were calculated. Three of the patients are currently alive. The median overall survival of the patients was 9 months (range 4-13 months). CONCLUSION: The present results suggest that surgery is a valuable treatment option for patients with advanced penile cancer. The prognosis of advanced penile cancer is closely related to lymph node and distant metastases. Flap repair can solve the problem of large area skin defect. Advanced penile cancer is difficult to treat regardless of chemotherapy or radiotherapy, and surgery cannot prolong the lives of patients. However, the dissection of lesions and repair of large area skin defects can dramatically improve the quality of life of patients, especially those with locally advanced disease without distant metastasis.
