Introduction: Internal urethrotomy is recommended for the treatment of urethral strictures shorter than 1.5 cm but has been associated with high recurrence rates. The aim of this study was to evaluate the efficacy of use of triamcinolone ointment for clean intermittent self catheterization in the prevention of urethral stricture recurrence after internal urethrotomy. Methods: Total of 60 male patients undergoing internal urethrotomy were assigned into two groups and clean intermittent self catheterization was performed using either triamcinolone ointment or a water-based gel for lubrication of the catheter in this randomized clinical trial. Clean intermittent self catheterization regimen was continued for 6 months and patients were followed for 12 months. Urethrocystoscopic evaluation was done 6 and 12 months postoperatively. Results: The recurrence rates were compared between the two groups. There were no significant differences in patient characteristics and etiology of the stricture between the two groups. There was a 6 (22.22%) recurrence rate in the patients of the triamcinolone group against 13 (46.42%) in those of the control group after the first internal urethrotomy (P=0.04). After second internal urethrotomy, the urethra was stabilized in 5 (83.3%) of the patients in the triamcinolone group and 8 (61.5%) those in the control group (P=0.05). We also found a significant correlation between recurrence and stricture length (P=0.02) but the time to recurrence was not statistically significant (P=0.16). Conclusions: The use of triamcinolone ointment in patients on CISC regimen after internal urethrotomy significantly decreased the stricture recurrence rate.

Aim To analyze clinical data from male patients treated with urethrotomy and to develop a clinical decision algorithm. Materials and methods Two large cohorts of male patients with urethral strictures were included in this retrospective study, historical (1985-1995, n=491) and modern cohorts (1996-2006, n=470). All patients were treated with repeated internal urethrotomies (up to 9 sessions). Clinical outcomes were analyzed and systemized as a clinical decision algorithm. Results The overall recurrence rates after the first urethrotomy were 32.4% and 23% in the historical and modern cohorts, respectively. In many patients, the second procedure was also effective with the third procedure also feasible in selected patients. The strictures with a length ≤ 2 cm should be treated according to the initial length. In patients with strictures ≤ 1 cm, the second session could be recommended in all patients, but not with penile strictures, strictures related to transurethral operations or for patients who were 31-50 years of age. The third session could be effective in selected cases of idiopathic bulbar strictures. For strictures with a length of 1-2 cm, a second operation is possible for the solitary low-grade bulbar strictures, given that the age is > 50 years and the etiology is not post-transurethral resection of the prostate. For penile strictures that are 1-2 cm, urethrotomy could be attempted in solitary but not in high-grade strictures. Conclusions We present data on the treatment of urethral strictures with urethrotomy from a single center. Based on the analysis, a clinical decision algorithm was suggested, which could be a reliable basis for everyday clinical practice.

Abstract Background Many urologists prefer Visual internal urethrotomy (VIU)because of its ease to perform, short hospital stay, low cost, and perceived low complication rate. They may repeat VIU several times to avoid complex urethral reconstruction, because it requires significant surgical experience. Because of its effectiveness and simplicity, VIU is the primary treatment option for urethral stricture disease. However, the recurrence rate is high and the success rate is low. Aim of the Work To evaluate the effect of hyaluronic acid (HA) instillation during visual internal urethrotomy (VIU) for decreasing the incidence of recurrent urethral stricture. Patients and Methods A total of 50 patients who were treated by Visualized internal uretherotomy for urethral stricture between February 2017 and January 2019 were invited to participate in the present study. This study is a multicenter,prospective, randomized controlled, single-blinded study. Results In this study the experimental group had a better voiding symptoms than the control group six months after the surgery,The present study showed that the instillation of hyaluronic acid into the urethra during visualized internal urethrotomy didn’t significantly reduced the recurrence of urethral stricture after the operation although the number of patients who had recurrence after hyaluronic acid instillation were less than recurrence rate in the control group. The hyaluronic acid had no observed side effects and helped to improve the pain and quality of life after the surgery. Conclusion The instillation of hyaluronic into the urethra during VIU reduced postoperative pain and improved voiding symptoms in the study group , but it didn’t significantly reduce the recurrence of urethral stricture after the operation. we suggest that a large-scale, randomized controlled trial be conducted in a larger number of patients with long-term follow-up .

Urethral strictures can significantly impact the quality of life for patients because it can be associated with significant complications such as fistulas, bladder calculi, infections and sepsis. Additionally, it might even lead to renal failure. The worldwide prevalence of urethral strictures is high, with an estimated rate of 229-627 patients per 100,000 population. In this literature review, the aim was to discuss the types and etiology of urethral strictures and the recurrence rates following the different management modalities. Studies that were included in this review were published between January 2005 until May 2021. The results support the current evidence that the idiopathic and iatrogenic bulbar strictures are the most common types while penile strictures, the iatrogenic and inflammatory are the most common causes. Recurrence rates are reported after management with almost all of the current management modalities, indicating the need for better interventions to enhance the outcomes and alleviate the quality of care. The recurrence rate of strictures after treatment with internal urethrotomy and direct vision internal urethrotomy by three years is 65%. Other studies reported that the rate of recurrence was estimated to be around 14 after 6 months from internal urethrotomy and up to 27% after 12 months. The rate of complications and recurrence following treatment with anastomotic urethroplasty was estimated to be less than 5%. Detailed information and discussion were provided in the study manuscript.

Purpose: we aimed to compare the longterm outcome of surgical treatment of urethral stricture with the internal urethrotomy and plasmakinetic energy. Material and Methods: 60 patients, who have been operated due to urethral stricture were enrolled in our clinic. None of the patients had a medical history of urethral stricture. The urethral strictures were diagnosed by clinical history, uroflowmetry, ultrasonography and urethrography. The patients were divided two groups. Group 1 consisted of 30 patients treated with plasmakinetic urethrotomy and group 2 comprised 30 men treated with cold knife urethrotomy. Results: There were no statistically significant differences between two groups in terms of patient age, maximum flow rate (Qmax) and quality of life score (Qol) value. A statistical difference between the two groups was observed when we compared the 3rd-month uroflowmetry results. Group 1 patients had a mean postoperative Qmax value of 16,1 ± 2,3 ml/s, whereas group 2 had a mean postoperative Qmax value of 15,1 ± 2,2 ml/s (p < 0.05). In the cold knife group, 3 of 11 (27,7%) recurrences appeared within the first 3 months, whereas in the plasmakinetic group zero recurrences appeared within the first 3 months in our study. The urethral stricture recurrence rate up to the 12 month period was statistically significant for group 1 (n = 7, 23%) compared with group 2 (n = 11, 37%) (p < 0.05). Conclusion: We believe that plasmakinetic surgery is better method than the cold knife technique for the treatment of urethral stricture.

Introduction: Many valid option modalities are available for the management of urethral stricture disease (USD), such as internal urethrotomy which has the success rates of 33%–60%. The aim of this study was to assess the outcome of holmium: YAG (Ho: YAG) laser urethrotomy (HLU). Methods: One hundred thirty-eight patients with urethral stricture with the mean age of 48±3.03 years old treated by HLU from March 2011 to August 2017. The main purpose of this investigation was to evaluate mean operation time, stricture recurrence rate and post-operation Qmax and complications of transurethral HLU. Results: The most common cause of USD was trauma in 82 (59.4%) patients. Mean laser operation time, mean hospital stay and mean postoperative duration of catheterization were 23.08 ± 9.1 minutes, 19.02 ± 10.7 hours and 10.3 ± 1.05 days respectively. The mean Qmax was 8.3 ± 2.07 mL/s before surgery and 16 ±3.1 mL/s afterward. At the end of 12 months follow-up, a total of 37 (26.8%) patients developed recurrence of the stricture. Patients with posterior, longer urethral strictures and previous history of interventions have more recurrence rate of the stricture. Conclusion: HLU is minimally invasive and seems to be an effective and safe management option for primary, short, urethral strictures. The hospital stay is remarkably short and complications are negligible.

Background: Urethroplasty is often successful for the treatment of male urethral stricture disease, but limited data exists on recurrence management. Our goal was to evaluate direct visual internal urethrotomy (DVIU) as a treatment option for isolated, recurrent strictures after urethroplasty. Methods: We retrospectively identified male patients who underwent urethroplasty from 1999 to 2013 and developed an isolated, recurrent stricture at the urethroplasty site treated with DVIU. Success was defined as lack of symptomatology and no subsequent intervention. Comparative analysis identified characteristics and stricture properties associated with success. Results: A total of 436 urethroplasties were performed in 401 patients at our institution between 1999 and 2013. Stricture recurrence was noted in 64 (16%) patients. Of these, 47 (73%) underwent a DVIU. A total of 37 patients met inclusion criteria and underwent 50 DVIU procedures at the urethroplasty site. A single DVIU was successful in 13 of 37 patients (35%). A total of 4 of 6 patients required a second DVIU (67%). Overall, 17 of 43 (40%) of the total DVIUs were successful after urethroplasty. Success did not differ by age, stricture length or location, surgical technique, radiation history, prior urethroplasty or DVIU, time to failure, or etiology. Conclusions: Post-urethroplasty DVIU for isolated, recurrent strictures may be offered as a minimally invasive treatment option. Approximately 40% of patients were spared further intervention.

For strictures with a length of 1-2 cm, a second operation is possible for the solitary low-grade bulbar strictures, given that the age is > 50 years and the etiology is not post-transurethral resection of the prostate. For penile strictures that are 1-2 cm, urethrotomy could be attempted in solitary but not in high-grade strictures. Conclusions: We present data on the treatment of urethral strictures with urethrotomy from a single center. Based on the analysis, a clinical decision algorithm was suggested, which could be a reliable basis for everyday clinical practice.

Purpose E75 is an immunogenic peptide from the HER2/neu protein that is highly expressed in breast cancer. We are conducting a clinical trial of an E75 + granulocyte-macrophage colony-stimulating factor vaccine to assess safety, immunologic response, and the prevention of clinical recurrences in patients with disease-free, node-positive breast cancer (NPBC). Patients and Methods Fifty-three patients with NPBC were enrolled and HLA typed. HLA-A2+ patients (n = 24) were vaccinated, and HLA-A2− patients (n = 29) are observed prospectively as clinical controls. Local/systemic toxicities, immunologic responses, and time to recurrence are being measured. Results Only minor toxicities have occurred (one grade 3 [4%]). All patients have demonstrated clonal expansion of E75-specific CD8+T cells that lysed HER2/neu-expressing tumor cells. An optimal dosage and schedule have been established. Patients have developed delayed-type hypersensitivity reactions to E75 postvaccination compared with controls (33 v 7 mm; P < .01). HLA-A2+ patients have been found to have larger, more poorly differentiated, and more hormonally insensitive tumors compared to HLA-A2− patients. Despite this, the only two deaths have occurred in the control group. The disease-free survival in the vaccinated group is 85.7% compared to 59.8% in the controls at 22 months' median follow-up with a recurrence rate of 8% compared to 21%, respectively (P < .19). Median time to recurrence in the vaccinated patients was prolonged (11 v 8 months), and recurrence correlated with a weak delayed-type hypersensitivity response. Conclusion This HER2/neu (E75) vaccine is safe and effective in eliciting a peptide-specific immune response in vivo. Induced HER2/neu immunity seems to reduce the recurrence rate in patients with NPBC.
