Objective:To investigate the efficacy of pelvic floor neuromuscular stimulation combined with progesterone in the treatment of pelvic floor function recovery after hysterectomy.Methods:This study used a randomized controlled design, involving 108 patients with pelvic floor dysfunction who underwent hysterectomy at Shaanxi Provincial People's Hospital between January 2021 and December 2023. These patients were randomly assigned to either a control group or an observation group, with 54 patients in each group, using a random number table for allocation. Both groups received basic pelvic floor muscle training. The control group was treated solely with progesterone vaginal soft capsules, while the observation group also received neuromuscular stimulation through pelvic rehabilitation equipment. Before and after treatment, changes in muscle strength (measured by electromyography values of type I and type II muscle fibers), quality of life (assessed using the Pelvic Floor Dysfunction Index Questionnaire-7 and the Pelvic Floor Distress Inventory-Short Form 20), pelvic relaxation indicators (levels of laminin, relaxin, and transforming growth factor beta-3), and Pelvic Organ Prolapse Quantification staging were compared between the two groups. Additionally, stress urinary incontinence, lumbosacral pain, sexual satisfaction, vaginal prolapse conditions, and overall efficacy post-treatment were compared between the two groups.Results:After treatment, electromyography values for type I and type II muscle fibers in the observation group were (4.71 ± 0.61) μA and (5.63 ± 0.79) μA, respectively, which were significantly higher than those in the control group [(3.51 ± 0.53) μA, (4.53 ± 0.50) μA, t = -10.91, -8.65, both P < 0.001]. The scores for the Pelvic Floor Dysfunction Index Questionnaire-7 and Pelvic Floor Distress Inventory-Short Form 20 in the observation group were (4.56 ± 0.64) and (4.56 ± 0.64), respectively, both of which were significantly lower than those in the control group [(5.36 ± 0.70), (5.36 ± 0.70), t = 6.20, 26.74, both P < 0.001]. The levels of laminin, relaxin, and transforming growth factor beta-3 in the observation group were (27.28 ± 3.00) μg/L, (53.32 ± 6.40) μg/L, and (28.25 ± 3.67) mg/L, respectively, all of which were significantly lower than those in the control group [(32.14 ± 3.54) μg/L, (59.22 ± 6.51) μg/L, (36.25 ± 3.99) mg/L, t = 7.70, 4.75, 10.84, all P < 0.001]. The proportion of patients in the observation group with a POP-Q stage of 0 was 90.74% (49/54), which was significantly higher than that in the control group [68.52% (37/54), χ2=8.22, P < 0.05]. The proportion in the observation group with a stage of 1 was 7.41% (4/54), which was significantly lower than that in the control group [25.93% (14/54), χ2 = 6.67, P < 0.05]. The incidence rates of stress urinary incontinence, lumbosacral pain, sexual dissatisfaction, and vaginal prolapse in the observation group were all significantly lower than those in the control group ( χ2 = 4.41, 4.36, 4.70, 4.41, all P < 0.05). The overall effective rate in the observation group was 92.59% (50/54), which was significantly higher than that in the control group [74.07% (40/54), χ2 = 6.67, P < 0.05]. Conclusions:Pelvic floor neuromuscular stimulation combined with progesterone vaginal soft capsules can improve muscle strength in patients with pelvic floor dysfunction after hysterectomy, enhance life satisfaction, relieve pelvic relaxation, and promote comprehensive recovery of pelvic function.

Objective To explore the erectile function preservational mechanism of Non-transecting urethroplasty(NTU) for posterior urethral stricture.Methods From May 2012 to September 2016,62 patients with posterior urethral stricture,who were treated with NTU,were enrolled in this study.The mean age was 37.5 years old,ranging 18-48 years old.The causes were pelvic fracture urethral injury in 53 cases and iatrogenic injury in 9 cases.Preoperative urethrography and urethroscopy revealed the strictures located in posterior urethra,which was at the distal of verumontanum.The mean length of stricture was 2.1 cm,ranging 0.5-2.5 cm.The average period between trauma and surgery was 6.4 months,ranging 3 months-2 years.All patients had no previous history of urethroplasty.Their sexual hormones were in normal level.Among those patients,the IIEF-5 scores were more than 12 and number of events during NPT test were more than twice.Finally,43 cases were underwent NTU and 19 cases accepted inferior pubectomy (IP)+ NTU.All patients had a general anesthesia.The bulbar urethra was mobilized dorsally from the tunica albuginea of the corpora cavernosa and then extended proximally up toward the perineal membrane.Scar tissue surrounding the urethra was excised and inferior pubectomy (IP) was performed as a supplemental technique to keep the suturing position without tension.The ventral hemi-circumference was then sutured with interrupted 4-0 polyglycolic sutures with tension-free anastomosis.The 18-Fr indwelling catheter was inserted.Result Average follow-up was 20.2 months,ranged from 12 to 36 months.In NTU group,NPT test revealed no significant difference in number of events (2.7 ± 0.7 vs.3.0 ± 1.0,P ＞ 0.05),duration of best episode [(16.4 ± 3.5) min vs.(16.4 ± 3.8) min,P ＞ 0.05)] or tip rigidity [(31.2 ± 4.7) ％ vs.(30.8 ± 3.5) ％,P ＞ 0.05)] between pre-and post-operation,respectively.The IIEF-5 score (19.7 ± 1.9 vs.20.4±2.1,P＜0.05)and Qmax[(8.7 ±4.0)ml/s vs.(25.5 ±4.7)ml/s,P＜0.05)] increased significant pre-and post-operation,respectively.In IP + NTU group,Qmax [(8.4 ± 4.4) ml/s vs.(23.1 ± 3.5)ml/s,P ＜ 0.05)] increased significant pre and post operation.The NPT test revealed slight decrease in number of events(2.3 ± 0.6 vs.1.6 ± 1.0,P ＜ 0.05),duration of best episode [(15.6 ± 2.4) min vs.(14.5±2.4)min,P＜0.05)] or tip rigidity [(29.8±3.0)％ vs.(25.6 ±7.1)％,P＜0.05)] between pre-and post-operation,respectively.However,the IIEF-5 scores (17.3 ± 1.6 vs.16.5 ± 2.1,P ＜ 0.05) didn't show significant difference pre-and post-operation.Stricture recurrence occurred in 3 patients,the success rate was 95.2％ (59/62) during 12 months following.Conclusion NTU is not only a safe and promising procedure for posterior urethral stricture less than 2.5cm,but also a new minimally invasive approach to preserve erectile function.

Objective To study the diagnostic value of 3-dimensional CT reconstruction in posterior urethral strictures or ankylurethria.Methods Thirty patients with strictures or ankylurethria of posterior urethra caused by pelvic fracture underwent helical CT scan and 3-dimensional reconstruction of the urethral canal as well as radiographic urethrography before and post open urethral reconstruction to observe the urethral anatomy,the length and position of the urethral strictures,the depth of periurethral scar.Results The mean stricture or ankylurethria length measured by radiographic urethrography was 4.0 cm (range from 1.0 cm to 7.0 cm),and the correlation coefficient of stricture or ankylurethria length was 0.92,21 (70%) patients were diagnosed accurately by radiographic urethrography.The mean stricture or ankylurethria length measured by 3-dimensional CT reconstruction was 4.3 cm (range from 1.2 cm to 7.6 cm),and the correlation coefficient of stricture or ankylurethria length was 0.96,there were 28(93%) patients diagnosed accurately by 3-dimensional CT reconstruction.The mean stricture or ankylurethria length measured by open urethral reconstruction was 4.2 cm (range from 1.5 cm to 7.5 cm).Five patients with urethrorectal fistula were also diagnosed accurately by 3-dimensional CT reconstruction rather than by radiographic urethrography.Conclusions 3-dimensional CT reconstruction of the urethral canal can accurately evaluate the urethral anatomy,the length and position of the urethral strictures,as well as the depth of periurethral scar after crush injury and provide useful information for operation that may not be provided by radiographic urethrography.3-dimensional CT reconstruction may become the most valuable means for detecting posterior urethra strictures or ankylurethria with urethrorectal fistula.
