Laparoscopic orchidopexy for the treatment of cryptorchidism in adults: a description of the technique and outcomes.

Background: There are few studies on cryptorchidism in adults, and its treatment is still controversial.

Methods: To summarize the surgical strategy and clinical efficacy of laparoscopic orchidopexy for the treatment of cryptorchidism in adults, 37 adult cryptorchidism patients were retrospectively analyzed between September 2017 and February 2022. All 37 patients underwent laparoscopic orchidopexy, of whom 33 underwent inguinal hernia repair without tension.

Efficacy and safety of aildenafil citrate in Chinese men with erectile dysfunction: a multicenter, randomized, double-blind, placebo-controlled crossover trial.

Background: To evaluate the efficacy and safety of aildenafil citrate in the treatment of erectile dysfunction (ED) in Chinese population.

Methods: A multicenter, randomized, double-blind, placebo-controlled, double-cycle crossover trial was conducted in three medical centers. Male patients with mild to moderate ED were randomized into two groups and received either aildenafil citrate or placebos, followed by a crossover administration after a 7-day washout.

Efficacy and safety of pulsatile gonadotropin-releasing hormone therapy in patients with congenital hypogonadotropic hypogonadism: a multicentre clinical study.

Background: Pulsatile gonadotropin-releasing hormone (GnRH) therapy may restore function of the hypothalamus-pituitary-gonad axis and induce spermatogenesis in male patients with congenital hypogonadotropic hypogonadism (CHH). The study sought to test the reliability of a newly developed Innopump hormone pump, and to confirm the efficacy and safety of pulsatile GnRH therapy (by Innopump hormone pump) in CHH patients.

Methods: From November 2017 to November 2018, 28 male patients with CHH were treated with pulsatile GnRH at Peking Union Medical College Hospital, Beijing Chaoyang Hospital, and Shandong Provincial Hospital.

Restoration of antegrade ejaculation after transurethral bladder neck injection of Deflux for retrograde ejaculation: a case report of natural conception.

Retrograde ejaculation contributes to male infertility. Pharmacotherapy has a limited role in retrograde ejaculation. Deflux, a viscous substance, consists of two components: dextranomer microspheres and stabilized hyaluronic acid for the treatment of children with vesicoureteral reflux.

[Application value of elastic ultrasound and contrast-enhanced ultrasonography in evaluating testicular blood supply after blockage of the vas deferens artery].

Objective: To explore the application value of elastic ultrasound (EUS) and contrast-enhanced ultrasonography (CEUS) in detecting the changes of testicular blood supply after blockage of the vas deferens artery.

Methods: This study included 11 cases of microscopic varicocele ligation. We obtained the EUS and CEUS values of the patients before and after blocking the vas deferens artery and analyzed the data by paired comparison.

[Plasmakinetic enucleation of the prostate versus holmium laser enucleation of the prostate for benign prostatic hyperplasia].

Objective: To evaluate the clinical effects of plasmakinetic enucleation of the prostate (PKERP) and holmium laser enucleation of the prostate (HoLEP) in the treatment of BPH.

Methods: We retrospectively analyzed the clinical data on 78 BPH patients treated by PKERP (n = 38) or HoLEP (n = 40) from January 2016 to October 2017. We recorded the operation time, intraoperative hemoglobin level, catheter-indwelling time, bladder irrigation time, hospital stay, 6-month postoperative IPSS, quality of life (QOL), maximum urinary flow rate (Qmax), postvoid residual urine (PVR), PSA level, International Index of Erectile Function (IIEF) and postoperative complications, and compared the obtained parameters between the two groups and some of them with the baseline.

Clinical features of haematospermia associated with seminal vesicle calculi versus posterior urethral haemangioma.

To compare the clinical features of seminal vesicle calculi(SVC) versus posterior urethral haemangioma(PUH) to assist urologists in differentiating and diagnosing the causes of haematospermia. Patients with SVC or PUH were included. Patient age, disease duration, hospital stay, operation time, symptoms, surgical approach, pathological results and postoperative complications were recorded.

Therapeutic effects of adipose-derived stem cells-based microtissues on erectile dysfunction in streptozotocin-induced diabetic rats.

This study aimed to explore the therapeutic effects of adipose-derived stem cells (ADSCs)-based microtissues (MTs) on erectile dysfunction (ED) in streptozotocin (STZ)-induced diabetic rats. Fifty-six 8-week-old Sprague-Dawley rats received intraperitoneal injection of STZ (60 mg kg-1 ), and 8 weeks later, the determined diabetic rats randomly received intracavernous (IC) injection of phosphate buffer solution (PBS), ADSCs, or MTs. Another eight normal rats equally got IC injection of PBS.

Effects of Icariside II on corpus cavernosum and major pelvic ganglion neuropathy in streptozotocin-induced diabetic rats.

Diabetic erectile dysfunction is associated with penile dorsal nerve bundle neuropathy in the corpus cavernosum and the mechanism is not well understood. We investigated the neuropathy changes in the corpus cavernosum of rats with streptozotocin-induced diabetes and the effects of Icariside II (ICA II) on improving neuropathy. Thirty-six 8-week-old Sprague-Dawley rats were randomly distributed into normal control group, diabetic group and ICA-II treated group.

Conversion of adipose-derived stem cells into natural killer-like cells with anti-tumor activities in nude mice.

Efforts to develop peripheral blood-derived nature killer (NK) cells into therapeutic products have been hampered by these cells' low abundance and histoincompatibility. On the other hand, derivation of NK-like cells from more abundant cell sources such as embryonic stem cells (ESCs) and umbilical cord blood (UCB) requires the selection of rare CD34+ cells. Thus, we sought to convert adipose-derived stem cells (ADSCs), which are abundant and natively CD34+, into NK-like cells.
