PRAMEF12, a novel cancer/testis gene, regulates proliferation and apoptosis to promote progression of glioma.

Aim: To evaluate whether PRAMEF12 can serve as a diagnostic biomarker for glioma. Methods: We examined PRAMEF12 expression in multiple normal and glioma tissues. The diagnostic value of PRAMEF12 was evaluated using receiver operating characteristic curve analysis. The effect of PRAMEF12 ablation on proliferation, cell cycle and apoptosis was investigated. Database analyses were utilized for functional enrichment analysis. Results: PRAMEF12 expression in normal tissue was restricted to the human testis. PRAMEF12 displayed significant diagnostic value in glioma. PRAMEF12 knockdown inhibited cell proliferation, induced apoptosis and resulted in induction of S-phase cell cycle arrest. Pathway enrichment analysis indicated that PRAMEF12 may participate in cancer. Conclusion: PRAMEF12, a novel cancer/testis gene, may be a potential new diagnostic biomarker for glioma.

The effect of Tai Chi/Qigong on depression and anxiety symptoms in adults with Cancer: A systematic review and meta-regression.

OBJECTIVE: We expand on prior systematic reviews of Tai chi/Qigong (TCQ) practice on depression or anxiety symptoms in adults with cancer to estimate the mean effect of TCQ on depression and anxiety in randomized controlled trials. Additionally, we perform moderator analysis to examine whether effects vary based on patient features, TCQ stimuli properties, or characteristics of research design. METHODS: Guided by PRISMA guidelines, we located articles published before August 31, 2023 using a combination of electronic database search and a complementary manual search through reference lists of articles and published reviews. Two separate multilevel meta-analyses with random-effects model were employed to estimate the overall effect of TCQ on depression and anxiety respectively. Further, multilevel meta-regression analysis was utilized to examine moderating effects based on moderators derived from patient features, TCQ stimuli properties, or characteristics associated with research design. Meta-analyses were performed in R4.0.0 and certainty of evidence with GRADEpro software. RESULTS: The TCQ intervention yielded a standardized mean effect size of 0.29 (95% CI, 0.18 to 0.40) for anxiety, indicating homogeneity among the included studies. Conversely, for depression, the standardized mean effect size was 0.35 (95% CI, 0.14 to 0.55), signifying heterogeneity: reductions were larger when the trial primary outcome, predominantly function-related outcomes, changed significantly between the TCQ and control group. CONCLUSIONS: TCQ practice exhibits small-to-moderate efficacy in alleviating depression and anxiety symptoms among cancer patients and survivors. Moreover, patients with depressive symptoms for whom TCQ intervention coupled with improvements in function-related outcomes manifested greater antidepressant effect.

Cumulative sum learning curve analysis of tubularized incised plate repair for hypospadias: a study of a single surgeon with a single surgical procedure.

Purpose: To ascertain the quantity of instances by which a single surgeon achieves competency and proficiency in using tubularized incised plate (TIP) technique for the repair of distal and mid-shaft hypospadias using the cumulative sum (CUSUM) analysis. Methods: We retrospectively evaluated patients with distal and mid-shaft hypospadias who were treated by a single surgeon between 2015 and 2021, using a single primary TIP technique with a de-epithelialized Byars flap. Data including type of hypospadias, age at surgery, curvature, operation time (OT), length of the reconstructed urethra, and postoperative outcomes were collected and assessed. CUSUM was used to assess the trends in OT and complication rate (CR) in order to generate the learning curve. The evolution of OT and CR can be divided into three phases: learning, competence, and proficiency. Results: CUSUM identified three phases in the learning curves of all TIP repairs. The median OT decreased from 135 min [interquartile range (IQR) = 125-155] to 92 min (IQR = 80-100) (P < 0.001), CR decreased from 28 (28%) to 8 (5.3%) (P < 0.001), and reoperations decreased from 15 (15.2%) to 4 (2.6%) (P < 0.001). According to the CUSUM learning curve, technical competency plateaued after the 99th case, and both OT and CR entered a significantly declining proficiency phase after the 231st case. Further, when the neourethral length exceeded the total average, total complications, urethrocutaneous fistula, and reoperations increased (P = 0.013, P = 0.006, and P = 0.028, respectively). Conclusions: Our study suggests that surgeons performing TIP repair may reach technical competency and achieve proficiency after operating on 99,231 cases, respectively. Moreover, the longer the neourethral length, the higher is the CR.

Metabolic-associated fatty liver disease in relation to site-specific and multiple-site subclinical atherosclerosis.

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) and the newly proposed metabolic-associated fatty liver disease (MAFLD) were each associated with subclinical atherosclerosis. However, there is limited evidence on risk of atherosclerosis in individuals who meet the criteria for one but not the other. We aimed to investigate the associations of MAFLD or NAFLD status with site-specific and multiple-site atherosclerosis. METHODS: This is a prospective cohort study involving 4524 adults within the MJ health check-up cohort. Logistic regression model was used to estimate odds ratios (ORs) and confidence intervals (CIs) for subclinical atherosclerosis (elevated carotid intima-media thickness [CIMT], carotid plaque [CP], coronary artery calcification [CAC] and retinal atherosclerosis [RA]) associated with MAFLD or NAFLD status, MAFLD subtypes and fibrosis status. RESULTS: MAFLD was associated with higher risks of elevated CIMT, CP, CAC and RA (OR: 1.41 [95% CI 1.18-1.68], 1.23 [1.02-1.48], 1.60 [1.24-2.08], and 1.79 [1.28-2.52], respectively), whereas NAFLD per se did not increase risk of atherosclerosis except for elevated CIMT. Individuals who met both definitions or the definition for MAFLD but not NAFLD had higher risk of subclinical atherosclerosis. Among MAFLD subtypes, MAFLD with diabetes had the highest risk of subclinical atherosclerosis, but the associations did not differ by fibrosis status. Stronger positive associations were observed of MAFLD with multiple-site than single-site atherosclerosis. CONCLUSIONS: In Chinese adults, MAFLD was associated with subclinical atherosclerosis, with stronger associations for multiple-site atherosclerosis. More attention should be paid to MAFLD with diabetes, and MAFLD might be a better predictor for atherosclerotic disease than NAFLD.

Effect of Prolonging the Duration of Stenting on Urethral Stricture in Proximal Hypospadias with Severe Curvature Repair: A Prospective Cohort Study.

INTRODUCTION: The aim of this study was to evaluate whether prolonged stenting reduces the risk of urethral stricture after proximal hypospadias (PH) with severe curvature (SC) repair. MATERIALS AND METHODS: We prospectively studied a cohort of patients with PH with SC repair who underwent urethral plate transection and urethroplasty between January 2010 and December 2020. According to the duration of stenting, the patients were divided into 2-, 4-, and 6-week groups. Postoperative complications and time of urethral stricture occurrence were analyzed. RESULTS: In total, 665 patients were included in the analysis. The overall incidence of complications was 26.6% (n = 177), including 42 cases of urethral strictures: 27 (64.3%) cases of urethral stricture occurred between 4 and 6 weeks after urethroplasty, 7 cases occurred between 7 weeks and 6 months after urethroplasty, 7 cases occurred more than 6 months after urethroplasty, and 1 case occurred at 3 weeks after urethroplasty. The incidence of urethral stricture in the 6-week group (1.8%) was significantly lower than that in the 4- (5.8%) and 2-week groups (10.9%) (p < 0.05). CONCLUSION: Prolonged stenting reduces the risk of urethral stricture in PH with SC repair. Four to six weeks after PH with SC repair may be the key period for the formation of early urethral strictures.

Long-term, single-center study comparing open and laparoscopic procedures for congenital midureteral obstruction in children.

PURPOSE: To compare the safety and outcomes of open and laparoscopic procedures in the management of congenital midureteral obstruction in children (CMO). METHODS: Between February 2008 and February 2022, a total of 18 patients underwent open ureteroureterostomy (OU group), and 26 underwent laparoscopic ureteroureterostomy (LU group). The operative time, postoperative hospital stay, hospital costs, postoperative complications, and success rates of the two groups were compared. RESULTS: The median age of the patients was 59 months, with 29 patients presenting with asymptomatic hydronephrosis, 12 with intermittent abdominal pain, and 3 with flank mass. The median follow-up time was 42 months, and all patients were successfully treated surgically. The operative time and postoperative hospital stay in the LU group were shorter than those in the OU group (106.3 ± 21.4 vs. 85.8 ± 16.5 min, 11.6 ± 1.9 vs. 8.3 ± 1.7 days, respectively; p < 0.05). The OU group had two postoperative complications, both of which were classified as Clavien-Dindo grade II based on the Clavien-Dindo classification. One case of postoperative complication occurred in the LU group, which was classified as Clavien-Dindo Grade II. There was no significant statistical difference in complications between the two groups (P > 0.05). CONCLUSIONS: Our data showed that laparoscopic ureteroureterostomy is a safe and effective treatment for congenital midureteral obstruction in children, and provides several advantages, including fewer postoperative complications, shorter postoperative hospital stay, and a shorter operative time. Laparoscopic procedures should be the first choice for treating children with congenital midureteral obstructions.

The comparative effects of Tai chi versus non-mindful exercise on measures of anxiety, depression and general mental health: A systematic review and meta-analysis.

BACKGROUND: Tai chi has been commonly used as an allied health strategy that can support the improvement of mental health for individuals, yet the comparative effects of Tai chi versus non-mindful exercise on measures of anxiety, depression and general mental health are unknown. This study aims to quantitatively estimate the comparative effects between Tai chi and non-mindful exercise on measures of anxiety, depression, and general mental health and examine whether selected moderators of theoretical or practical importance moderate the effects. METHODS: Consistent with PRISMA guidelines for conduct and reporting, we located articles published before 31 Dec 2021 using Google Scholar, Pubmed, Web of Science, EBSCO (PsycArticles, PsycExtra, PsycInfo, Academic Search Premier, ERIC, MEDLINE). To be included in the analysis, studies were required to have (1) a design that randomly assigned participants to Tai chi and non-mindful exercise comparison condition or group. (2) anxiety, depression, or general mental health outcome measured at baseline and during or after Tai chi and exercise intervention. Study quality was judged using the tool for assessing study quality and reporting in exercise (TESTEX) for randomized controlled trials (RCTs). Three separate multilevel meta-analyses with random effects were performed to estimate the comparative effects of Tai chi versus non-mindful exercise on psychometric measures of anxiety, depression, and general mental health respectively. In addition, possible moderators were assessed accordingly for each meta-analysis. RESULTS: Twenty-three studies that included measures of anxiety (10), depression (14), and general mental health (11) involved 4370 participants (anxiety, 950; depression, 1959; general mental health,1461) and yielded 30 effects on anxiety, 48 on depression, and 27 on general mental health outcomes. Tai Chi training consisted of 1-5 sessions per week, 20-83 min per session, and 6-48 weeks. After adjusting for nesting effects, the results showed significant small-to-moderate effects of Tai chi versus non-mindful exercise on the measure of anxiety (d = 0.28, 95 % CI, 0.08 to 0.48), depression (d = 0.20, 95 % CI, 0.04 to 0.36), and general mental health (d = 0.40, 95 % CI, 0.08 to 0.73). Further moderator analyses showed that baseline general mental health T-score and study quality influenced the effects of Tai chi versus non-mindful exercise on measure of general mental health. CONCLUSION: Compared to non-mindful exercise, the small body of studies reviewed here tentatively supports that Tai chi is more effective in reducing anxiety and depression and improving general mental health than non-mindful exercise. Higher-quality trials are needed to standardize Tai chi and non-mindful exercise exposure, quantify mindfulness elements in Tai chi practice, and control expectations on conditions to better determine the psychological effects of both exercise properties.

Association between trajectories of fasting plasma glucose and risk of osteoporosis in non-diabetic and diabetic populations.

Introduction: Previous studies based on a single measure of fasting plasma glucose (FPG) showed an inconsistent conclusion about the association between FPG and osteoporosis risk. Not accounting for time-varying and cumulative average of FPG over time could bias the true relation between FPG and osteoporosis. Our study aims to investigate the association between the trajectories of FPG and osteoporosis risk for non-diabetic and diabetic populations. Methods: A total of 18,313 participants who attended physical examinations during 2008-2018 were included. They were free of osteoporosis at their first physical examination and followed until their last physical examination before December 31, 2018. We recorded their incidence of osteoporosis and at least three FPG values during follow-up. Their longitudinal FPG trajectories were identified by the latent class growth analysis model based on the changes in FPG. Multivariable logistic regression models were used to analyze the association between the trajectories of FPG and osteoporosis diagnosed in the follow-up physical examination in both non-diabetics and diabetics. Results: There were 752 incident osteoporosis among 16,966 non-diabetic participants, and 57 incident osteoporosis among 1,347 diabetic participants. Among non-diabetics, the elevated-increasing FPG trajectory was negatively associated with osteoporosis risk in women (odds ratio (OR), 0.62; 95% confidence interval (CI), 0.43-0.88). Premenopausal women with elevated-increasing FPG trajectory had lower osteoporosis risk than those women with normal-stable FPG trajectory (OR, 0.41; 95% CI, 0.20-0.88), while this association was insignificant in postmenopausal women. Among diabetics, those whose longitudinal FPG is kept at a very high level had the highest risk of osteoporosis (OR, 3.09; 95% CI, 1.16-8.22), whereas those whose FPG starts with the high level and keeps on increasing did not exhibit a significantly increased risk (OR, 1.75; 95% CI, 0.81-3.76) compared with those who keep stable moderate-high level of FPG, except in men (OR, 2.49; 95% CI, 1.02-6.12). Conclusion: Distinct trajectories of FPG are associated with differential risk of osteoporosis in non-diabetic and diabetic populations. Controlling a proper FPG level in different populations is necessary for osteoporosis prevention.

The efficacy of topical 0.1% mometasone furoate for treating symptomatic severe phimosis: A comparison of two treatment regimens.

Background: Twice daily 0.1% mometasone furoate is an effective treatment for phimosis in children. However, mometasone furoate has an important therapeutic advantage because it is effective in once-daily applications. This study was to compare the efficacy of two different topical 0.1% mometasone furoate regimens for the treatment of symptomatic severe phimosis in pediatric patients. Methods: A total of 1,689 patients with symptomatic severe phimosis classified by the Kikiros system were prospectively enrolled in the study from March 2018 to February 2021. A total of 855 patients received 0.1% mometasone furoate twice-daily (BID group) and 834 patients received 0.1% mometasone furoate once-daily (QD group) for 4 weeks. Results: A total of 1,595 boys completed the treatment (798 and 797 in the BID and QD groups, respectively). The success rate of the BID group was higher than that of the QD group at the end of week 2 (44.8% vs. 33.3%, P < 0.05), while there was no difference in the success rate at 4 weeks and 3 months between the two groups (70.7% vs. 69.7%, and 66.8% vs. 64.9%, respectively) (P > 0.05). In both treatment groups, the success rate of grade 5 phimosis was lower than that of grade 4 at 2 weeks, 4 weeks, and 3 months. A total of 83 patients experienced recurrence of phimosis. Only fifteen patients had local mild adverse drug reactions. Conclusion: Topical application of 0.1% mometasone furoate once-daily or twice-daily for 4 weeks had comparable efficacy in children with symptomatic severe phimosis. A once a day regimen may be more suitable for children. Topical steroid application is more effective in children with low-grade phimosis than those with high-grade phimosis.

Diagnostic value of ultrasound in children with transverse testicular ectopia.

Objective: The study aimed to investigate the diagnostic value of ultrasound in children's transverse testicular ectopia (TTE). Materials and methods: We retrospectively studies all TTE cases diagnosed in our hospital from January 2017 to December 2021. All cases were evaluated by ultrasound examination and compared to physical examination and diagnostic laparoscopy results. Results: This study included 14 TTE patients in total, with a median age was 1.08 years. In the 14 TTE, physical examination found 10 TTE cases, of which nine testes were located in the opposite scrotum, one testis was located in the opposite groin, and the other four testes were not observed by physical examination. All cases were diagnosed by preoperative ultrasound, and nine testes were located in the opposite scrotum, two testes were located in the opposite groin, and three testes were located next to the opposite iliac vessel in the abdominal cavity. Preoperative ultrasound showed the ectopic spermatic cord in six cases (6/14, 42.8%) and persistent Müllerian duct syndrome (PMDS) in one case (1/14, 7%). Diagnostic laparoscopy finally confirmed 14 cases of TTE, which was consistent with preoperative ultrasound, and the coincidence rate was 100% (14/14). Among the 14 cases of TTE, diagnostic laparoscopy showed that 12 cases had ectopic spermatic vessels and vas deferens (12/14, 85.7%), and six cases were associated with PMDS (6/14, 42.8%). When TTE was associated with the ectopic spermatic cord and PMDS, the diagnostic performance of diagnostic laparoscopy was better than that of preoperative ultrasound (P < 0.05). The testis volume of the affected side of TTE was less than that of the contralateral testis (P < 0.05). Conclusion: Ultrasonography is very helpful for the preoperative diagnosis of TTE in children, and it is suitable as a non-surgical method for locating ectopictestis. Preoperative assessment of the exact presence of PMDS is difficult and unclear. This may be related to factors such as pelvic developmental stages in infancy, examination techniques, and atypical imaging findings of PMDS.

Association between metabolically healthy obesity and non-alcoholic fatty liver disease.

BACKGROUND: The risks of NAFLD and NAFLD with fibrosis progression among metabolically healthy obesity (MHO) individuals are largely unexplored. This cohort study investigated the association between MHO as well as other metabolic syndrome-obesity combined phenotypes and NAFLD and its fibrosis progression. METHODS: Participants included 31,010 adults from a health check-up cohort free from NAFLD and intermediate or high probability of advanced fibrosis at baseline. Metabolically healthy was defined as not having any component of metabolic syndrome. Obesity was identified by body mass index (BMI) and waist circumference (WC). Participants were cross-classified by metabolic health and obesity at baseline. The outcomes were NAFLD, and NAFLD with fibrosis progression, as assessed by abdominal B-type ultrasound and noninvasive fibrosis score. RESULTS: During a median follow-up of 2.2 (interquartile range, 1.2-4.9) years, 7,393 participants developed NAFLD. MHO individuals (HR 5.51, 95% CI 4.98, 6.09 for BMI criteria; HR 6.76, 95% CI 6.04, 7.57 for WC criteria) had a significantly higher risk of NAFLD than those with metabolically healthy normal weight or low WC. The corresponding HRs (95% CIs) for metabolically healthy overweight (defined by BMI) and medium WC were 2.74 (2.49-3.02) and 2.93 (2.65-3.24), respectively. Furthermore, 557 participants developed NAFLD with fibrosis progression. The association between different obesity phenotypes and NAFLD with fibrosis progression also showed a similar pattern. CONCLUSION: MHO was associated with significantly higher risks of NAFLD and its fibrosis progression, suggesting that regarding NAFLD prevention, MHO individuals might still benefit from lifestyle interventions aimed at body weight and WC maintenance.

A simple technique to repair distal and mid-shaft hypospadias using a de-epithelialized Byars' flap.

OBJECTIVE: To describe standard and modified de-epithelialized Byars' flap techniques in tubularized incised plate urethroplasty and evaluate postoperative outcomes. METHODS: We retrospectively evaluated data for 404 primary hypospadias repair patients who underwent standard (Group A) or modified (Group B) urethroplasty between January 2016 and 2021. Group B's data were analyzed to evaluate whether our modified technique was effective for all hypospadias types. RESULTS: There was no difference in the ratio of different hypospadias types between Groups A (n = 145) and B (n = 259). Median follow-up duration was 35 months. Fistula occurred in 19 patients in Group A and 12 in Group B (statistically significant difference). The total complication rate was statistically significantly different between the groups. In Group B, 3/142 patients with distal hypospadias developed urethrocutaneous fistula vs 4/95 with mid-shaft hypospadias and 5/22 with proximal hypospadias. No difference was noted between the distal and mid-shaft groups. Significant differences were observed when comparing distal and mid-shaft groups with the proximal group; total complication rates were similar. Glans dehiscence and meatal stenosis rates were similar between Groups A and B, and among the hypospadias phenotypes. CONCLUSION: Our modified procedure is simple to perform and yields excellent results in distal and mid-shaft hypospadias repair.

Risk factors for postoperative complications in children with proximal hypospadias with severe chordee who underwent urethral plate transection.

OBJECTIVES: To identify the risk factors associated with developing complications after transection of the urethral plate for proximal hypospadias with severe chordee. METHODS: We used a prospective database to identify patients with proximal hypospadias and severe chordee who underwent transection of the urethral plate and primary hypospadias repair in 2011 and 2021. All patients underwent urethroplasty with a follow-up period of >12 months. The association between variables (age, surgical technique, length of urethral defect, and surgeon volume) and postoperative complications (fistulas, urethral strictures, diverticula and glans dehiscence) was analyzed. RESULTS: Altogether, 493 patients were included, of whom 133 (26.9%) had postoperative complications. Univariate and multivariate analyses revealed that the preoperative proximal meatal position, one-stage repair, longer urethral defect length, and low surgeon volume were significant risk factors for postoperative complications with proximal hypospadias with severe chordee who underwent transection of the urethral plate. A urethral defect length of ≥4.55 cm was considered the best cutoff value for predicting postoperative complications. CONCLUSIONS: Preoperative proximal meatal location, one-stage repair, longer urethral defect length, and low surgeon volume were associated with postoperative complications in patients with proximal hypospadias with severe chordee who underwent transection of the urethral plate. A urethral defect length of ≥4.55 cm was significantly associated with the development of complications.

Association between Dietary Patterns Reflecting C-Reactive Protein and Metabolic Syndrome in the Chinese Population.

It is unclear how the dietary patterns reflecting C-reactive protein (CRP) affect metabolic syndrome (MetS) in the Chinese population. To examine the effect of the dietary pattern reflecting CRP with MetS, a cross-sectional study was based on the health checkup data from the Beijing MJ Health Screening Centers between 2008 and 2018. The CRP-related dietary pattern was derived from 17 food groups using reduced-rank regression. Participants were divided into five groups according to the quintiles of dietary pattern score. Multivariate logistic regression was then applied to estimate the odds ratios (OR) and 95% confidence intervals (CIs) for the quintiles of diet pattern score related to MetS and its four components. Of the 90,130 participants included in this study, 11,209 had MetS. A CRP-related dietary pattern was derived, characterized by a higher consumption of staple food, fresh meat, processed products, and sugar-sweetened beverages but a lower intake of honey and jam, fruits, and dairy products. Compared with participants in the lowest quintile (Q1), participants in the higher quintiles were associated with increased risks of MetS in a dose−response manner after adjustment for potential confounders (p for linear trend < 0.001), the ORs for Q2 to Q5 were 1.10 (95% CI: 1.02−1.19), 1.14 (95% CI: 1.05−1.22), 1.23 (95% CI: 1.15−1.33), and 1.49 (95% CI: 1.38−1.61), respectively. Moreover, the effects were stronger among individuals aged 50 years or older. A CRP-related dietary pattern was associated with the risk of MetS. It provides new insights that dietary intervention to achieve a lower inflammatory level could potentially prevent MetS.

Association of Sleep Duration with Hyperuricemia in Chinese Adults: A Prospective Longitudinal Study.

Little is known about the association of sleep duration with hyperuricemia. Especially lacking is evidence from longitudinal studies. Based on the MJ Health Examination Database in Beijing, China, a prospective study was designed. Participants were classed into short, normal, and long groups by sleep duration. The Cox regression model was used to estimate the hazard risk of hyperuricemia for short or long sleep duration compared with the normal group after adjusting for potential confounders. During a median 3.08 years follow-up, 4868 (14.31%) incident hyperuricemia events were documented among 34,025 participants with a crude incidence rate of 39.49 per 1000 persons. Years after adjusting for potential confounders, a 7% higher risk of hyperuricemia in the short sleep duration group (<7 h, 95% confidence interval: 1.01−1.14) and a 15% lower risk in the long sleep duration group (≥8 h, 95%CI: 0.74−0.97) were found compared with the normal group (7−8 h) (p for trend < 0.001). Nevertheless, the association of the short sleep duration group was marginally significant after further adjustment of the count of white blood cells (hazard ratio: 1.07, 95%CI: 1.00−1.13). Sleep duration was inversely associated with hyperuricemia, which highlights the public health significance of sufficient sleep duration for preventing hyperuricemia.

Anatomical Laparoscopic Orchiopexy and Hybrid Transscrotal Orchiopexy for High Inguinal Undescended Testis: A Novel and Interfascial Technique.

Background: In traditional laparoscopic orchiopexy for inguinal undescended testis (UDT) surgery, the testicles are pulled back into the abdominal cavity by grasping and cephalad retracting the testicle and the cord. If this fails, a subsequent open inguinal incision is made to complete orchiopexy. To improve the orchiolysis and avoid extra open inguinal incision, we describe our early experience with and illustrate the surgical procedure of a novel anatomical laparoscopic orchiopexy (ALO) and hybrid transscrotal orchiopexy as required in high palpable UDT. Methods: From March 2018 to April 2020, ALO was performed in 140 consecutive patients (158 testes) with high inguinal UDT. After blunt and bloodless dissection of the inter-tunica vaginalis-cremasteric fascia plane, tunica vaginalis enveloping the testis was brought into the abdominal cavity as a whole. When the tunica vaginalis was unable to be brought into the abdominal cavity, given that the orchiolysis had already been partially carried out, the testis could be brought out of the external ring and descended when converting to transscrotal surgery. Results: The mean age in this study was 1.88 years (standard deviation ±1.95). The position of the testis assessed at surgery was peeping (58, 36.7%) and canalicular (100, 63.3%). In 128 testes (81.1%), ALO brought the UDT into the abdominal cavity; the remaining 30 testes (18.9%) required a hybrid transscrotal technique. All testes were descended without conversion to open inguinal procedure. The mean operative time was 43.9 ± 9.2 minutes. All patients had follow-up within a median of 17.8 months, with satisfactory results in relation to viability and location of the testis. Conclusions: ALO was shown to be not only safe, feasible, and effective for high inguinal UDT but also facilitated subsequent hybrid transscrotal orchiopexy; when the testis failed to be pulled into the abdominal cavity, the conversion to open inguinal orchiopexy could be obviated.

Open Versus Laparoscopic Gubernaculum-Sparing Second-Stage Fowler-Stephens Orchiopexy for Intra-Abdominal Testis: A Long-Term Study.

Background: The benefits of performing open versus laparoscopic gubernaculum-sparing second-stage Fowler-Stephens orchiopexy (FSO) remain unclear. We compared the two techniques to answer this question. Methods: We retrospectively studied a cohort of patients who underwent laparoscopic first-stage FSO and open versus laparoscopic gubernaculum-sparing second-stage FSO at our institution between September 2004 and June 2020 (all patients underwent surgery by a single surgeon). We evaluated both procedures based on the incidence of testicular atrophy, testicular ascent, and other complications. Results: The age at initial surgery was 45.7 ± 28.2 months (median, 39). One hundred nine cases were treated with open second-stage gubernaculum-sparing FSO (OFSO), and 96 cases were treated with laparoscopic second-stage gubernaculum-sparing FSO (LFSO). The mean follow-up period was 59.8 months (median, 54; standard deviation, +35). The overall testicular atrophy rate was 1.5%. Atrophy was observed in 2 and 1 patient in the OFSO and LFSO groups, respectively (1.8% versus 1.0%, P > .05). There was no significant difference in the incidence of testicular ascent between both groups (2.8% versus 3.1%). Five and four complications were noted in the OFSO and LFSO groups, respectively (P > .05). Conclusions: Second-stage gubernaculum-sparing FSO achieved high testicular survival rates and satisfactory testicular positions. Neither the open nor laparoscopic approach appeared superior, because the overall testicular survival rates and incidence of testicular ascent and other complications were equivalent between both groups.

Hypospadias With Severe Chordee: Effect of Urethral Plate Transection on Penile Length.

OBJECTIVE: To present our experience with urethral plate (UP) transection to treat hypospadias with severe chordee and examined the effects of this procedure on penile length. The technique involved transecting the UP to correct curvature, facilitating elongation of penile length and reconstruction of the urethra. METHODS: We prospectively studied a cohort of patients with hypospadias with severe chordee who underwent UP transection and urethroplasty at our institution between February 2012 and March 2020. The length of the UP defect (length of penile elongation), complications, and patient and urologist satisfaction with penile length were analyzed. RESULTS: A total of 510 children were included in our study: 78 cases of distal hypospadias and 432 cases of proximal hypospadias. The mean age at initial surgery was 34.84 ± 20.10 months. The length of the UP defect after transection was 2.51 ± 0.92 cm (1.6-8.0 cm). The length of the UP defect gradually increased with age (P < .05). Seven patients were "poorly satisfied" with their penile length after urethroplasty. The median follow-up duration was 32 months. Of the 510 patients, 108 (21.1%) had complications after urethroplasty, including urethral fistulas in 86 cases, urethral strictures in 9 cases, urethral diverticulum in 8 cases and glans dehiscence in 5 cases. During the follow-up period, 7 patients had mild chordee. CONCLUSION: Transecting the UP for hypospadias with severe chordee can elongate penile length, reduce the recurrence of curvature, and improve patient satisfaction.

Urethroplasty for chordee with a paper-thin hypoplastic urethra: A long-term study.

OBJECTIVES: To establish a standard surgical procedure for children with chordee with a paper-thin hypoplastic urethra, which was based on the degree of curvature and urethral plate quality. To guidelines for the management of this disorder. METHODS: We reviewed 58 cases of chordee with a paper-thin hypoplastic urethra, managed between March 2006 and September 2020. The age of the patients ranged from 23 to 89 months. Operative details and postoperative complications were analyzed. RESULTS: Mild-moderate chordee with a paper-thin hypoplastic urethra correction was performed using a tubularized incised plate (13 cases) or onlay island flap (five cases) technique after penile degloving. Severe chordee with a paper-thin hypoplastic urethra required transection of the urethra and underwent a Duckett (11 cases) or staged (29 cases) urethroplasty. Complications in the tubularized incised plate and onlay island flap groups were 7.7% and 20%, respectively. The overall complication rate was 10.3% in the staged group and 27.3% in the Duckett group. CONCLUSIONS: Reconstruction of the entire hypoplastic urethra should be recommended in the management of chordee with a paper-thin hypoplastic urethra. We propose an algorithm based on the degree of curvature and urethral plate quality. The tubularized incised plate or onlay island flap technique can be used for mild to moderate chordee with a paper-thin hypoplastic urethra, and the outcome of the tubularized incised plate technique tends to be better than that of the onlay island flap technique. Duckett or staged urethroplasty is suitable for severe chordee with a paper-thin hypoplastic urethra, and the staged technique can improve the overall success rate.

Efficacy of one- and two-stage segment urethroplasty for severe chordee with congenital short urethra.

OBJECTIVES: The aim of this study was to analyze the efficacy of segment urethroplasty to treat severe chordee with congenital short urethra and compared one-stage and two-stage segment urethroplasty. This procedure involved urethral transection to correct the chordee, and urethroplasty was performed to restore natural penile length. METHODS: We retrospectively studied a cohort of patients with severe chordee and congenital short urethra who underwent one- or two-stage segment urethroplasty at our institution between February 2006 and May 2020. We evaluated the efficacy of the procedures based on the incidence of complications. RESULTS: A total of 37 children were included in this study: 25 were treated with two-stage segment urethroplasty and 12 were treated with one-stage segment urethroplasty. The median length of neourethra in the one-stage repair group (3.21 cm) was similar to that in the two-stage repair group (3.23 cm; P > 0.05). Of the 37 patients, 32 (86.5%) were cured after urethroplasty. There were three patients with complications in the one-stage repair group (one urethral fistula and two urethral strictures) and two patients with fistula in the two-stage repair group. Among the five patients with complications, the three fistulas were successfully repaired through reoperation and the two urethral strictures were cured after urethral dilatation. No patient had diverticulum or recurrent chordee. CONCLUSIONS: Segment urethroplasty achieved satisfactory outcomes in the treatment of severe chordee with congenital short urethra. This can restore natural penile length, and the recurrence rate of severe chordee is low. The overall success rate of the two-stage procedure tends to be better than that of the one-stage procedure.
