Ultimately, the aim is to provide simple and rapid control of the DVC, as well as better tumour control and postoperative urinary control function.…”

Radical prostatectomy has undergone a development from open to laparoscopic surgery to a surgical robotic approach. With improved surgical equipment and the continuous development of surgical techniques, various surgical strategies for controlling the dorsal vascular complex (DVC) during RP have been investigated, which affect intraoperative blood loss, postoperative tumour control and postoperative urinary and sexual function. The present narrative review summarizes the latest anatomical information about the prostatic apex and DVC and then describes the three types of DVC control. More detailed anatomy of the DVC is required and the optimal DVC control under different situations needs further research.

Objective To analyze the effect of transvesical laparoscopic radical prostatectomy (TVLRP) on sexual function and urinary continence. Method The data of 72 patients diagnosed with low-risk and localized prostate cancer, who underwent treatment at our hospital between January 2017 and June 2022, were retrospectively analyzed. All these patients underwent TVLRP under general anesthesia. Their serum prostate-specific antigen (PSA), urinary continence and erectile function were statistically analyzed. Results The operation went well with no intraoperative difficulties. The average surgical duration of 102 ± 22 min, coupled with the minimal intraoperative blood loss of 100 ± 32 mL, underscored the precision and efficacy of the surgical techniques employed. Following surgery, postoperative pathological assessments confirmed staging, revealing pT2a in 18 cases and pT2b in 54 cases, suggestive of localized tumors. Gleason scores ≤ 6 further indicated well-differentiated tumors, while consistently negative surgical margins affirmed the complete resection of tumors, reducing the likelihood of disease recurrence. Subsequent to the surgical intervention, the the average hospital stay was 13.94.1 days. A comprehensive 12-month follow-up revealed exceptionally high urinary continence rates, with 97.8% and 100% of patients achieving continence at 1 and 3 months postoperatively, respectively. Moreover, progressive improvement in erectile function recovery was observed, with recovery rates at 3, 6, and 12 months postoperatively reaching 82.2%, 88.4%, and 93.5%, respectively. There was no biochemical regression. Conclusion Treatment of low-risk and localized prostate cancer by TVLRP has a satisfactory urinary continence and recovery of erectile function after operation, less and complications and definite tumor-control effect.

ObjectiveThis study aimed to design a low-cost, simulation training platform for the ligation of deep dorsal vein (DVC) complex in radical prostatectomy and validate its training effectiveness.MethodsA simplified prostate urethra model was produced by 0-degree silica gel and pulse pressure banding. This model was placed on a slope of about 30 degrees using cardboard to thus creating a narrow environment of the pelvis. The DVC ligation was performed by a 2D laparoscopy simulator. A total of 27 participants completed the study include 13 novices, 10 surgical residents and 4 urology experts. The novices were trained five trails with 24 hours interval, the residents and experts completed the DVC ligation once. The construct validity of this simulation training platform was performed by completing time, the GOALS (Global Operative Assessment of Laparoscopic Skills) and TSA (i.e. Task Specific Assessments) score. The face validity and content validity were performed by a specific closed-ended questionnaire.ResultsThere was no significant difference among three groups in demographic or psychometric variables (p > 0.05). Compared to the novices, the residents spend a shorter time to complete the DVC ligation (p < 0.05) and had higher GOALS scores (p < 0.05), but had no significant difference in TSA scores (p > 0.05). Additionally, the experts groups had a better performance compared to residents group in the completing time (p < 0.05), GOALS score (p < 0.05) and TSA score (p < 0.05). The learning curve of novices significantly promoted along with the increased times of training. Almost 90 percent of subjects considered that this simulator had a good performance in the realism and practicability.ConclusionWe developed a novel low-cost a simulation training platform for the ligation of deep dorsal vein complex in radical prostatectomy, and this simulator had a good performance in the construct validity, face validity and content validity.
