Selective dorsal neurotomy (SDN) is a surgical treatment for primary premature ejaculation (PE), but there is still no standard surgical procedure for selecting the branches of the dorsal penile nerves to be removed. We performed this study to explore the value of intraoperative neurophysiological monitoring (IONM) of the penile sensory-evoked potential (PSEP) for standard surgical procedures in SDN. One hundred and twenty primary PE patients undergoing SDN were selected as the PE group and 120 non-PE patients were selected as the normal group. The PSEP was monitored and compared between the two groups under both natural and general anesthesia (GA) states. In addition, patients in the PE group were randomly divided into the IONM group and the non-IONM group. During SDN surgery, PSEP parameters of the IONM group were recorded and analyzed. The differences in PE-related outcome measurements between the perioperative period and 3 months' postoperation were compared for the PE patients, and the differences in effectiveness and complications between the IONM group and the non-IONM group were compared. The results showed that the average latency of the PSEP in the PE group was shorter than that in the normal group under both natural and GA states (P < 0.001). Three months after surgery, the significant effective rates in the IONM and non-IONM groups were 63.6% and 34.0%, respectively (P < 0.01), and the difference in complications between the two groups was significant (P < 0.05). IONM might be useful in improving the short-term therapeutic effectiveness and reducing the complications of SDN.

For many years, surgical treatment of buried penis in children has been researched by several scholars, and numerous methods exist. This study aimed to explore the clinical effect of a modified fixation technique in treating buried penis in children. Clinical data of 94 patients with buried penis who were treated using the modified penile fixation technique from March 2017 to February 2019 in Fujian Maternity and Child Health Hospital (Fuzhou, China) were retrospectively collected, compared, and analyzed. Clinical data of 107 patients with buried penis who were treated using traditional penile fixation technique from February 2014 to February 2017 were chosen for comparison. The results showed that at 6 months and 12 months after surgery, the penile lengths in the modified penile fixation group were longer than those in the traditional penile fixation group (both P < 0.05). The incidence of postoperative skin contracture and penile retraction in the modified penile fixation group was less than that in the traditional penile fixation group (P = 0.034 and P = 0.012, respectively). When the two groups were compared in terms of parents' satisfaction scores, the scores for penile size, penile morphology, and voiding status in the modified penile fixation group were higher than those in the traditional penile fixation group at 2-week, 6-month, and 12-month follow-ups after surgery (all P < 0.05). We concluded that the modified penile fixation technique could effectively reduce the incidence of skin contracture and penile retraction and improve the penile length and satisfaction of patients' parents.

We aimed to evaluate ten-year outcomes of penile prosthesis (PP) implantation for the treatment of erectile dysfunction and to assess predictors of early prosthetic infection (EPI). We identified 549 men who underwent 576 PP placements between 2008 and 2018. Univariate and multivariate analyses were used to identify potential predictors of EPI. An EPI predictive nomogram was developed. Thirty-five (6.1%) cases of EPI were recorded with an explant rate of 3.1%. In terms of satisfaction, 82.0% of the patients defined themselves as "satisfied," while partner's satisfaction was 88.3%. Diabetes (P = 0.012), longer operative time (P = 0.032), and reinterventions (P = 0.048) were associated with EPI risk, while postoperative ciprofloxacin was inversely associated with EPI (P = 0.014). Rifampin/gentamicin-coated 3-piece inflatable PP (r/g-c 3IPP) showed a higher EPI risk (P = 0.019). Multivariate analyses showed a two-fold higher risk of EPI in diabetic patients, redo surgeries, or when a r/g-c 3IPP was used (all P < 0.03). We showed that diabetes, longer operative time, and secondary surgeries were the risk factors for EPI. Postoperative ciprofloxacin was associated with a reduced risk of EPI, while r/g-c 3IPP had higher EPI rates without an increased risk of PP explant. After further validation, the proposed nomogram could be a useful tool for the preoperative counseling of PP implantation.

The aim of this article is to assess the outcomes of a low-intensity extracorporeal shock wave therapy (LiESWT) protocol for the treatment of Peyronie's disease (PD). Patients treated for PD were prospectively recorded, and data were retrospectively reviewed. Age, characteristics of fibrous plaques, concomitant treatments, International Index of Erectile Function (IIEF-5), Lue score, and pain score on Likert scale were collected. Patients in acute phase of PD and an angulation of <40° were included. The protocol consisted of 6 weekly sessions of 4000 pulses each, applied from different directions, with a maximal power of 20 W and 8 Hz frequency. We included 39 patients (median age: 56.8 years, interquartile range [IQR]: 35.8-62.2 years). The median number of sessions received per patient was 7.2. After treatment, the median Lue score decreased from 6.8 initially to 3.3 (P = 0.003), the median Likert pain score dropped from 1.8 to 0.7 (P = 0.004), the median plaque size was reduced from 2 cm to 1.2 cm (P = 0.08), and the median penile curvature diminished from 31° to 17° (P = 0.07). On univariate and multivariate analysis, the only predictors of success were younger age (odds ratio [OR] = 0.95, P = 0.03 and OR = 0.91, P = 0.04, respectively) and concomitant use of phosphodiesterase-5 inhibitors (PDE5i; OR = 0.92, P = 0.02 and OR = 0.93, P = 0.01, respectively). LiESWT had a favorable impact on Lue score and notably penile pain, curvature, plaque size, and erectile function in patients treated for PD during the early inflammatory phase, with no side effects. Younger age and concomitant use of PDE5i were the only success predictors.

Genital dissatisfaction is well known in female and adults. Less is known about male adolescents and their genital satisfaction. The aim of this study was to investigate and report the role of surgery in male adolescents to improve the evaluation of their genitalia. We considered all patients treated for external genital pathology in the period of adolescence. Inclusion and exclusion criteria were created. Patients underwent an evaluation test before and after surgery. During the study period, 137 patients were treated, and at the end of the study, 98 cases were considered for analysis. The most frequent pathologies were webbed penis and penile curvature. A postoperative score improvement was noted and patients with concealed penis and webbed penis showed a better postoperative outcome. Overweight was considered an important factor associated with a worse preoperative score. Evaluation of the external genitalia is important in adolescents, and it is an understudied problem. Overweight may be associated with a worse evaluation of one's genital and should be clinically considered to avoid related social problems in adulthood. Therefore, cosmetic genital surgery should be considered even in male adolescents.

This study explored the usefulness of two-dimensional shear wave elastography (2D-SWE) in the early assessment of corpora cavernosa fibrosis (CCF). New Zealand male rabbits were randomly assigned to an experimental group or a control group. Recombinant human transforming growth factor beta 1 (TGF-β1) was injected into the dorsal penis tissue of rabbits in the experimental group. Conventional ultrasound and 2D-SWE examinations were performed before and 20 days after injection. Penile histological analysis was performed by hematoxylin-eosin staining, sirius red staining, and immunohistochemistry. Measurement of 2D-SWE examination results was performed using shear wave elastography quantitative measurement (SWQ). Histological analysis outcomes were the proportion of smooth muscle cells (SMCs), collagen fibers (CFs), collagen type I (Col I), and collagen type III (Col III), as well as the SMCs/CFs ratio, measured by sirius red staining. Other histological analysis outcomes were the positive area proportion (PAP) of TGF-β1 (PAPT), fibronectin (PAPF), and Col III (PAPC), measured by immunohistochemistry. After recombinant human TGF-β1 injection, SWQ was higher in the experimental group than that in the control group (P < 0.001); however, there were no differences in conventional ultrasound results. There were significant differences in histological outcomes between the two groups (all P < 0.05). These results indicated that 2D-SWE was superior for identifying early histological changes in CCF.
