[Application analysis of laparoscopic assisted microsurgical vasovasostomy in the treatment of vas deferens obstruction caused by inguinal herniorrhaphy].

OBJECTIVE: To investigate the effiicacy of laparoscopic assisted microsurgical vasovasostomy in the treatment of vas deferens obstruction caused by inguinal herniorrhaphy. METHODS: Clinical data of patients undergoing surgical treatment for deferential obstruction after inguinal hernia repair in the andrology department of the First Affiliated Hospital of Zhengzhou University from 2018 to 2022 were retrospectively analyzed, and they were divided into two groups according to different surgical methods: double mirror combined group and microscope group. The basic clinical data, intraoperative conditions, postoperative effects and complications of the two groups were compared. RESULTS: There were 14 cases in the double mirror group and 34 cases in the microscope group. There was no significant difference in age and history of groin operation between the two groups (P>0.05). The average length of hospital stay in the two-lens group was less than that in the microscope group (5.07±0.26 days vs 7.09±1.86 days, P< 0.01), and the average operation time in the two-lens group was more than that in the microscope group (211.93±58.55min vs 162.26±40.70min, P<0.01). The postoperative recurrence rate (85.7% vs 73.5%, P > 0.05) was similar between the two groups. There was no significant difference in early postoperative complications (0% vs 2.9%, P > 0.05). Only 1 patient in the microscope group experienced fat liquefaction and recovered after intensive dressing change. CONCLUSION: Laparoscope-assisted microscopy provides natural fertility opportunities for patients with vas deferens obstruction after inguinal hernia repair, reduces the difficulty of surgery and the length of hospital stay, and is a safe and effective surgical method comparable to traditional surgical methods.

Efficacy analysis of 26 cases of ejaculatory duct obstruction treated by prostatic utricle neck endoscopy.

Objective: To evaluate the safety and efficacy of transvesical incision in the treatment of ejaculatory duct obstruction. Methods: The clinical data of 26 male infertile patients with ejaculatory duct obstruction were retrospectively analysed at the First Affiliated Hospital of Zhengzhou University from June 2020 to August 2021. All patients were treated with seminal vesicle neck incision for ejaculatory duct obstruction. The general clinical characteristics, intraoperative conditions and postoperative effects on the patients were recorded, and the therapeutic effect was evaluated. Results: The ejaculatory duct was found through fenestration, and the seminal vesicle gland was smoothly entered in 25 patients (96.2%). Among them, 22 cases underwent bilateral endoscopy and three underwent unilateral endoscopy. Sperm appeared in 23 cases (88.5%) 3 months after surgery. The sperm concentration and motility postoperatively at 6 months were higher than that at 3 months postoperatively. No postoperative complications, such as epididymitis or retrograde ejaculation, occurred. Conclusion: Searching for the ejaculatory duct via the neck of the prostatic utricle, assisted by a low-energy holmium laser, is a new method for the treatment of ejaculatory duct obstruction. Microscopic vision is clear using this approach and the postoperative complications are few, which has high value for clinical application.

Analyzing the Clinical Efficacy of a Type 5 Phosphodiesterase Inhibitor Combined With Ziyin Baihuo Granules in the Treatment of Erectile Dysfunction.

The study explored the clinical efficacy of a type 5 phosphodiesterase inhibitor (PDE5i) combined with Ziyin Baihuo granules in the treatment of patients suffering from erectile dysfunction (ED) with yin deficiency and fire-hyperactivity syndrome. A total of 163 patients with erectile dysfunction were divided into observation and control groups. The observation group took tadalafil (Cialis) and Ziyin Baihuo granules orally, and the control group took only tadalafil orally, for 12 weeks. An additional 40 healthy people were selected as a normal group for comparison of the sex hormone levels before and after treatment of the participants in the erectile dysfunction group. After treatment, the symptoms of dry throat and tongue, tidal fever and night sweats, liking cold and avoiding heat, and waist pain showed significant improvement in the observation group (p < .05). Compared with before treatment, the clinical indexes of erectile function in the control group and the observation group were improved after treatment (p < .05). After treatment, Ziyin Baihuo granules combined with tadalafil restored the abnormal indexes of blood (p < .05) in the observation group. Our research shows that PDE5i combined with Ziyin Baihuo granules could effectively improve erectile function.

A Comparative Study on the Success Rates of Two Approaches for Seminal Vesiculoscopy.

This study aimed to compare the success rates of two approaches for seminal vesiculoscopy: through the interior of the prostatic utricle and through the neck of the prostatic utricle. The patients were divided into two groups based on the seminal vesiculoscopy used. Group A was an interior of the prostatic utricle group (152 cases), and group B was a neck of the prostatic utricle group (146 cases). The general clinical data, intraoperative conditions and surgical results of the two groups were compared. Compared with group A, group B had a higher surgical success rate (94.5% vs. 62.5%, p < .001), a shorter operation time (33 min vs. 45 min, p < .001), less blood loss (0.5 ml vs. 2 ml, p < .001), a higher pain relief rate (86.6% vs. 52.3%, p < .001), a higher remission rate of haemospermia (82.2% vs. 58.5%, p = .011), a lower recurrence rate of pain (10.4% vs. 35.4%, p < .001), a lower recurrence rate of haemospermia (15.6% vs. 37.7%, p = .014), a higher symptom remission rate of the lower urinary tract (90.9% vs. 50.0%, p = .030), a higher remission rate of scrotal moisture (84.6% vs. 45.5%, p = .042) and a higher remission rate of frequent spermatorrhea (80.0% vs. 55.6%, p = .033). Seminal vesiculoscopy undertaken through the neck of the prostatic utricle has the characteristics of high success rate, short operation time and good surgical effect and is worthy of promotion and application.

[Blood biochemical indexes in ED patients with kidney deficiency or non-kidney deficiency: A comparative analysis of 156 cases].

OBJECTIVE: To analyze the blood biochemical characteristics of the ED patients with different types of kidney deficiency or non-kidney deficiency. METHODS: We reviewed the clinical data on 156 ED patients treated in our Department of Andrology from May to July 2018 and, according to the traditional Chinese medicine (TCM) syndromes, divided them into four groups: kidney-yang deficiency (n = 48), kidney-yin deficiency (n = 34), kidney-yin+yang deficiency (n = 36) and non-kidney deficiency control (n = 38). We obtained and compared their blood biochemical indexes, including the levels of testosterone (T), estradiol (E2), cortisol (CORT), thyroid stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), nitric oxide (NO), total nitric oxide synthase (tNOS), and inducible nitric oxide synthase (iNOS). RESULTS: There were no statistically significant differences in the mean age, course of disease, IIEF-5 score and erection hardness score (EHS) among the four groups of patients. Pairwise comparison showed that, compared with the non-kidney deficiency controls, the patients in the kidney-yin deficiency group exhibited a dramatically higher level of CORT (ï¼»87.97 ± 45.59ï¼½ vs ï¼»121.78 ± 41.87ï¼½ µg/L, P = 0.002) and those in the kidney-yang deficiency group a remarkably lower level of FT3 (ï¼»5.44 ± 0.38ï¼½ vs ï¼»5.11 ± 0.54ï¼½ pmol/L, P = 0.008). The iNOS level was significantly higher in the kidney-yin deficiency group (14.42 ± 2.49 U/ml) than in either the control (12.71 ± 2.58 U/ml) (P = 0.039) or the kidney-yang deficiency group (13.05 ± 2.17 U/ml) (P =0.049). CONCLUSIONS: ED patients with different types of kidney deficiency syndromes have different blood biochemical indexes, which may help clarify the biological basis of the TCM syndromes of kidney deficiency in ED patients.

MiR-4295 promotes cell growth in bladder cancer by targeting BTG1.

microRNAs (miRNAs) have been demonstrated to contribute to tumor progression and metastasis, and have been proposed to be key regulators of diverse biological processes. In this study, we report that miR-4295 is deregulated in bladder cancer tissues and cell lines. To characterize the role of miR-4295 in bladder cancer cells, we performed functional assays. The overexpression of miR-4295 significantly promoted bladder cancer cell proliferation, colony formation, and migration. Moreover, its downregulation induced cell cycle arrest and apoptosis of bladder cancer cells. Furthermore, a luciferase reporter assay and rescue experiment indicated that miR-4295 directly targets BTG1 by binding its 3'UTR. In conclusion, these results demonstrate that miR-4295 acts as an oncogene and may be a potential biomarker for bladder cancer diagnosis and treatment.

[Bilateral ureteral polyps in children: a case report].

Fibroepithelial polyp of the ureter is a benign tumor of mesodermal origin that rarely occurs in children. The most common presenting symptoms are hematuria and flank pain by obstruction of the urinary tract. The etiology of this tumor is still not clear. It occurs more frequently in boys and often arises in the proximal ureter and the ureteropelvic junction. The preoperative diagnosis is difficult. We present here the case of a 11-year-old boy who had fibroepithelial polyps as the cause of the left flank ureteropelvic junction obstruction at pyeloplasty, and had the same condition on the right flank 5 years ago. We used polypectomy and pyeloureterostomy to treat the boy. No major intraoperative or preoperative complications developed.
