Assessment of diagnostic accuracy for cryptorchidism and risk factors for delayed orchidopexy.

OBJECTIVES: Cryptorchidism (CO) diagnosis by palpation is challenging. Patients with suspected CO are primarily referred to pediatric urologists by general pediatricians and urologists. Currently, surgical treatment for CO is recommended earlier than in previous guidelines. In this study, we evaluated factors that lead to diagnosis discordance and delayed orchidopexy in patients referred with suspected CO in addition to timing of initial screening. METHODS: In total, 731 patients (1052 testes) with suspected CO were included. Risk factors for diagnostic discrepancy in CO diagnosis by pediatric urologists and risk of delayed orchiopexy were evaluated. RESULTS: Herein, 659 (90%) patients were diagnosed during routine public health checkups for infants and young children, and 419 (57%) patients were referred by pediatric practitioners. Of 1052 testes, 374 (36%) were diagnosed with CO by pediatric urologists. In multivariate analysis, risk factors of diagnostic discrepancy for CO diagnosis by pediatric urologists were bilateral testis (odds ratio [OR] = 9.17, p < 0.0001), >6 months old at initial diagnosis (OR = 1.036, p < 0.0001), and pediatric referral (OR = 4.60, p < 0.0001). In total, 296 patients underwent orchiopexy for CO. In multivariate analysis, risk factors for delayed orchiopexy were presence of comorbidities (OR = 3.43, p = 0.003) and >10 months old at referral (OR = 12.62, p < 0.0001). CONCLUSIONS: Pediatric referral is a risk factor for discordant CO diagnostics, and late age at referral brings a risk of delayed orchiopexy. It is necessary to enlighten pediatricians, who are mainly responsible for routine health checkups, in teaching CO diagnostic techniques to ensure early referral.

Orchidopexy for congenital cryptorchidism in childhood and adolescence and testicular cancer in adults: an updated systematic review and meta-analysis of observational studies.

Congenital cryptorchidism is a well-established risk factor of testicular malignancies. However, there is still remarkable variability in the measures of associations between of these two clinical entities. The current meta-analysis investigates the up-to-date risk of testicular cancer in adults with a history of surgically corrected congenital cryptorchidism until adolescence. The meta-analysis was conducted with strict criteria for the identification of the congenital cryptorchidism cases that underwent surgery before adulthood. The study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search of the PubMed and the Scopus databases was conducted, using a defined strategy, from inception to February 2023. Two independent authors screened the literature and extracted the data, using inclusion and exclusion criteria. Of the 2176 articles identified, 93 articles were fully retrieved, and 6 articles met all the inclusion criteria. The Newcastle-Ottawa scale was applied for the studies' quality assessment. The random-effects model in RevMan 5.4 program was used for the meta-analysis. Three case-control studies and three cohort studies were selected. They included 371,681 patients and 1786 incidents of testicular cancer. The pooled odds ratio (OR) was 3.99 (95% confidence intervals (CI): 2.80-5.71). The heterogeneity was moderate and estimated at 51% with the I-squared statistic. A forest plot and a funnel plot were produced to evaluate the ORs and the probable publication bias, respectively. The mean Newcastle-Ottawa score was 8/9 for all the included reports.  Conclusion: This systematic review and meta-analysis verifies, with an updated estimate, the increased risk of testicular cancer in adults with an orchidopexy history. New evidence on the maldescent laterality supports that the cancer risk remains increased and for the contralateral, unaffected testicle, although to a lesser extent. The orchidopexy in the first year of life prevents the testicular damage and decreases the overall cancer risk. What is Known: • Congenital cryptorchidism is the commonest genitourinary abnormality and a risk factor for testicular cancer. • The most recent meta-analysis reporting this association was in 2013. What is New: • After reviewing literature until February 2023, the association of congenital cryptorchidism with testicular cancer risk in adulthood was verified: odds ratio=3.99 [2.80-5.71], 95% CI. • The meta-analysis highlights the protective role of early orchidopexy and the controversial data about maldescent and testicular cancer laterality.

Transverse testicular ectopia with persistent Mullerian duct syndrome: Report and review of two cases.

Transverse testicular ectopia is a rare anomaly characterized by both testes descending through a single inguinal canal. The objective of this study was to investigate the pathogenesis, diagnosis, and treatment of transverse testicular ectopia (TTE) with persistent Mullerian duct syndrome (PMDS), and to deepen the understanding of the disease in clinical. A retrospective analysis of the clinical manifestation, diagnosis, and treatment of two children suffering from TTE with PMDS was conducted. Previous studies on the characteristics, diagnosis, and treatment of this disease were reviewed. The two patients were treated with laparoscopy-assisted transseptal orchidopexy-inguinal evaluation. After the surgery, the two patients recovered well. The follow-up visits were done 3 months after the operation. An ultrasound examination confirmed that the two patients had testes in the orthotopic position and normal size. TTE with PMDS is an exceedingly rare disease. The patients manifested cryptorchidism on one side; contralateral inguinal hernia was suspected. Detailed physical and ultrasound examinations before the operation are the key to the early diagnosis of TTE. Laparoscopic evaluation is helpful for the diagnosis and finding of other abnormalities. Surgical treatment is the only method to cure the disease; long-term follow-up is needed after TTE operation.

Incidence of testicular microlithiasis after orchidopexy for cryptorchidism and its risk factors: A retrospective cohort study.

INTRODUCTION: Testicular microlithiasis (TML) is detected using scrotal ultrasound (US) and is characterized by hyperechoic non-shadowing foci 1-3 mm in diameter within the testicular parenchyma. Although a history of orchidopexy is a known risk factor for TML, and TML is a relatively common condition in postoperative cryptorchidism patients, no previous report has focused on risk factors for TML after orchidopexy. OBJECTIVE: The aims of this study were to evaluate the time-dependent incidence of TML after orchidopexy for cryptorchidism and to identify risk factors for TML. STUDY DESIGN: This study included patients who underwent primary orchidopexy for cryptorchidism between 2004 and 2018 and could be evaluated using scrotal US before and after the procedure. Patients with chromosomal abnormalities and those with preoperative TML were excluded. The Kaplan-Meier method was used to assess postoperative TML appearance. The Cox proportional hazard model was used to evaluate three potential risk factors for postoperative TML: higher testicular position (proximal to the external inguinal ring), delayed orchidopexy (after 18 months of corrected age), and bilateral cryptorchidism. RESULTS: A total of 214 testes from 163 patients were eligible for inclusion (operative age and follow-up time: 2.2 years ± 18 months and 6.3 years ± 46 months, respectively). TML was found in 14/163 patients (8.6%) and 17/214 testes (8.1%). No testicular tumors were discovered during follow-up. The time-dependent TML incidence was 6.0% at 5 years and 11.2% at 10 years after surgery (Summary figure). A higher testicular location proximal to the external inguinal ring was found to be an independent risk factor in the Cox proportional hazard model (hazard ratio 6.18, 95% confidence interval 1.37-27.9, Summary figure). DISCUSSION: Our findings show that the incidence of postoperative TML increases for approximately 10 years following orchidopexy and is associated with a higher testicular location proximal to the external inguinal ring at surgery. In the adult population, TML with a history of cryptorchidism is a known risk factor of testicular malignancy. Given that more than 20% of boys with a higher testicular position developed TML, US evaluation to detect TML during pubety is feasible for the patients with a history of orchidopexy. CONCLUSION: The incidence of postoperative TML in boys with cryptorchidism rises until puberty and is strongly associated with a higher testicular position at orchidopexy.

Recurrent testicular torsion post orchidopexy - an occult emergency: a systematic review.

BACKGROUND: Recurrent Testicular Torsion (RTT) is a rarely reported event after previous testicular torsion (TT) repair. Both conditions have similar signs and symptoms. Various techniques have been attempted to reduce the incidence of retorsion. This review assesses the presentation, diagnosis, risk factors, management and outcomes associated with RTT. METHODS: After PROSPERO Registration (CRD42021258997), a systematic search of PubMed, Google Scholar, Embase, Scopus, Web of Science, Cochrane Database of Systematic Reviews, Global Index Medicus and Cumulative Index to Nursing and Allied Health Literature (CIANHL) was performed using specific search terms. Study metadata including patient demographics, orchidopexy techniques, RTT rates and RTT timing were extracted. RESULTS: Twenty-six articles, comprising 12 case series and 14 case reports, with a total of 46 patients were included. Overall, the median (IQR) age of the pooled cohort was 18 (15-26) years, the median (IQR) time to presentation was 6 (3-36) hours from the onset of testicular pain. The most common presenting features were testicular pain (100%), testicular swelling (60.9%) and a high riding testicle (34.8%). The left testicle was most commonly affected (63.0%), RTT was on the ipsilateral side in relation to the primary episode of TT in 52.2% of cases, the median (IQR) interval between torsion and retorsion events was 4 (1.3-10.0) years, non-absorbable sutures were the most common suture material used during orchidopexy after RTT (88.9%). CONCLUSION: RTT is a rare presentation to the Emergency Department. Even with a prior history of TT, RTT should be considered in patients presenting with classic symptoms.

Prevalence, management, and outcome of cryptorchidism associated with gastroschisis: A systematic review and meta-analysis.

PURPOSE: Cryptorchidism associated with gastroschisis has been poorly investigated. We aimed to assess the prevalence of this association, and to address the management and outcome of cryptorchidism in this context. MATERIALS AND METHODS: In this systematic review, we searched electronic databases (PubMed, Web of Science, and Google Scholar), without language restrictions from inception to March 31, 2021, for studies on cryptorchidism and gastroschisis co-occurrence. Random effects meta-analysis was used to calculate pooled prevalence estimates of cryptorchidism in gastroschisis and spontaneous testicular descent in this population. RESULTS: Twenty-five studies were included for the systematic review. All were retrospective case reports or series for a total of 175 patients. Pooled prevalence estimate for cryptorchidism in gastroschisis was 19% (95% CI 13-26). Complete data sets for management and outcome analysis were available in 94 patients, involving 120 undescended testes [63 (52.5%) nonpalpable, 34 (28.3%) prolapsed outside the abdominal wall defect, and 23 (19.2%) palpable]. Fifty-five descended spontaneously, with a pooled prevalence estimate of 50% (95% CI 31-69). Twelve testes/remnants were primarily removed or absent, while 49 testes underwent orchiopexy (success rate, 63%). Excluding 4 testes still awaiting orchiopexy, 30 of the remaining 116 (25.8%) testes had a dismal outcome, including testicular loss (19), hypoplasia (8) or recurrent cryptorchidism (3). CONCLUSION: Cryptorchidism in gastroschisis appears to occur more frequently than in the normal population. The overall mediocre testicular outcome seems to reflect the most unfavorable presentation of cryptorchidism in gastroschisis, which is represented by originally intrabdominal or prolapsed testis in the majority of cases. LEVEL OF EVIDENCE: IV.

Timing of orchidopexy and its relationship to postoperative testicular atrophy: results from the ORCHESTRA study.

BACKGROUND: In 2011 a consensus statement from the British Association of Paediatric Urologists recommended lowering the age at orchidopexy to under 1 year. There are concerns that a younger age at operation may increase postoperative testicular atrophy. The ORCHESTRA study aimed to establish the current age at orchidopexy in a multicentre, international audit and to see whether testicular atrophy was affected by age at operation. METHODS: The study was undertaken over a 3-month period in 28 centres in boys undergoing orchidopexy for unilateral, palpable undescended testes. Data collection was done using a standardized, predetermined protocol. The primary outcome was postoperative testicular atrophy. Secondary outcomes were wound infections, reoperations, and unplanned hospital stays related to anaesthetic events. RESULTS: A total of 417 patients were included, of whom only 48 (11.5 per cent) underwent orchidopexy before 1 year of age. There was no difference in anaesthetic complications in boys aged less than 1 year versus older patients: 0 of 48 (0 per cent) versus 6 of 369 (1.6 per cent) (P = 0.999). Complete follow-up was available for 331 patients (79.4 per cent). There was no difference in atrophy rate between those aged less than 1 year and older boys: 1 of 37 (3 per cent) versus 9 of 294 (3.1 per cent) (P = 0.999). Reoperation rates were 0 of 37 (0 per cent) and 7 of 294 (2.4 per cent) respectively (P = 1.000). There were more wound infections in boys under 1 year of age: 4 of 37 (11 per cent) versus 7 of 294 (2.4 per cent) (P = 0.025). CONCLUSION: Only 11.5 per cent of boys underwent surgery before the age of 1 year. There was no increased risk of postoperative testicular atrophy with early surgery, although there was a higher rate of wound infection. Further study is required to demonstrate that early orchidopexy is not inferior to orchidopexy undertaken in boys aged over 1 year.

Laparoscopy-Assisted Transscrotal Orchidopexy for Palpable Undescended Testis: Initial Results.

Background: Undescended testis (UDT) is one of the most common congenital genital malformations in boys. However, orchidopexy carries a risk of injuring the testicular vessels and vas deferens. We therefore developed a novel approach to manage palpable UDT. Materials and Methods: We analyzed the medical records of patients who underwent orchidopexy at our institute between January 2017 and April 2020. This study was approved by the Institutional Review Board of our hospital. The age, body weight, laterality, testicular position, length of operation, and complications were investigated. The patients were classified into two groups depending on the surgery received: laparoscopy-assisted transscrotal orchidopexy (LATO) or conventional inguinal orchidopexy (CO). In brief, LATO involves preceding laparoscopic closure of the patent processus vaginalis (PPV) followed by transscrotal orchidopexy. Dissection of the PPV from the testicular vessels and vas deferens was minimized through this procedure. The chi-squared test and t-test were used to analyze the significance of the data. Results: Among a total of 49 patients, 24 (33 testes) underwent LATO, and 25 (30 testes) underwent CO. There was no significant difference in patients' age, body weight, or laterality. The length of operation was similar between the groups in both unilateral and bilateral cases. The contralateral PPV was confirmed in 80% of unilateral cases of LATO (12/15). No complications, including testicular atrophy and postoperative ascent, were noted in either group. Conclusions: There were no significant differences between the groups in the surgical results. However, the confirmation and ligation of the PPV were easier in LATO, and peeling of the testicular vessels and vas deferens was minimized. LATO may be safe and effective for managing palpable UDT.

A novel method of bilateral patent processus vaginalis ligation in transumbilical single-site multiport laparoscopic orchiopexy.

Objective: To evaluate safety and efficacy of a novel method of bilateral patent processus vaginalis ligation in transumbilical single-site multiport laparoscopic orchiopexy for children. Methods: A retrospective study was carried out comparing the novel ligation and conventional ligation performed by a single surgeon between July, 2017-July, 2018. The patients were divided into the novel group (42 cases) and the conventional group (59 cases). In the novel group, transumbilical single-site multiport laparoscopic orchiopexy was performed and the bilateral internal rings was stitched with "8" pattern suture. In the conventional group, the conventional TriPort laparoscopic orchiopexy was performed and purse string suture was used to fix the internal rings. The parameters of operative duration time, postoperative hospital stay; postoperative complications were compared between 2 groups. Results: All operations were successful. No Perioperative period complications were found and all patients were discharged within 4-6 days after operation. There is no statistic difference in the surgery time and hospitalization day. However, there is significant difference in the Pain face scale scores after day 2(1.60±0.73 VS 2.02±0.86). And there is no scar and the satisfactory cosmetic could be seen in scrotum and inguinal area in the novel group. Conclusion: The novel ligation was safety and efficacy. It is relatively easy to perform with smaller scar and less pain. We propose the novel ligation as a more viable treatment option for pediatric cryptorchidism with bilateral patent processus vaginalis.

Pre-operative skin antisepsis with chlorhexidine gluconate baths and wipes does not prevent postoperative surgical site infection in outpatient pediatric urologic inguinal and scrotal surgery.

INTRODUCTION: To reduce surgical site infections (SSI), many institutions utilize pre-operative antisepsis with chlorhexidine gluconate (CHG) baths and/or wipes. CHG reduces bacterial colonization of the skin, but it is unclear whether this reduces SSI, and current guidelines from the American College of Surgeons, the Centers for Disease Control, and the World Health Organization do not support this practice. There are several factors that increase the risk of SSI in adults, but there is limited understanding of these factors in pediatric patients. OBJECTIVES: The primary objectives were to describe the proportion of pediatric patients undergoing hernia/hydrocele repair and/or orchiopexy who develop a postoperative (postop) SSI and to determine whether pre-operative CHG baths/wipes were associated with SSI. The secondary objectives were to identify other factors associated with SSI and to estimate the cost of CHG baths/wipes in this population. STUDY DESIGN: Pre-operative antisepsis with CHG baths/wipes was implemented at the authors institution in 2006. The authors performed a retrospective cohort study of patients aged 0-18 years undergoing hernia/hydrocele repair and/or orchiopexy by a pediatric urologist at their institution before (2004) and after (2008) the introduction of CHG. The authors compared the proportion of patients with SSI in the no CHG and CHG groups and evaluated for factors associated with SSI. Statistical analysis included Wilcoxon rank-sum test, Chi-squared test, and Fisher's exact test. The cost of CHG baths and wipes was estimated using institutional fees in 2018 US dollars. RESULTS: A total of 543 patients met inclusion criteria, 203 in the no CHG group and 340 in the CHG group. The overall rate of SSI was 0.92%. There was no association between use of CHG and SSI. No patient or peri-operative factors were associated with development of SSI. There were no CHG-associated adverse events. The cost of materials was estimated at $3.29/patient ($1118.60 for 340 cases in 2008) in 2018 US dollars. DISCUSSION: SSI is not common in pediatric patients undergoing hernia/hydrocele repair or orchiopexy. In the present study, pre-operative antisepsis with CHG baths/wipes is not associated with a reduction in SSI and carries additional cost. CONCLUSIONS: To the authors knowledge, this is the first study to evaluate the use of pre-operative antisepsis with CHG baths/wipes in an exclusively pediatric population. In the study, CHG baths/wipes add cost with no clear benefit for reducing SSI in pediatric patients undergoing hernia/hydrocele repair and/or orchiopexy.

Postoperative pain in small-for-gestational age infants after hernia repair, orchidopexy and urethral reconstruction surgery: A pilot study.

BACKGROUND: Small-for-gestational-age (SGA) birth bears an enhanced risk of developing hypertension, obesity, insulin resistance and mental health disorders in later life as a consequence of adaptive processes in utero. Only a small number of studies on pain perception in SGA infants exist. These are indicative of a blunted stress response to pain in SGA newborns. AIM: We initiated a pilot study investigating differences in postoperative pain perception between SGA and appropriate-for-gestational-age (AGA) infants. METHODS: Pain and alertness levels of 10 formerly SGA and 14 AGA infants at the age 0.5-2 years were evaluated by the FLACC scale, Steward and Aldrete Scores following hernia repair, reconstructive surgery of hypospadia and orchidopexy. In addition, the postoperative consumption of non-steroidal anti-inflammatory drugs was compared between SGA and AGA. RESULTS: Postoperative pain and alertness levels were not significantly different in SGA and AGA children. We did not observe significant group differences regarding the consumption of non-steroidal anti-inflammatory drugs. CONCLUSION: While previous studies were suggestive of a suppressed stress response to pain in SGA newborns, these findings did not fully translate into an altered response to pain beyond the newborn age. Further studies in a larger cohort seem necessary to verify this finding.

Inconsistency in Opioid Prescribing Practices After Pediatric Ambulatory Hernia Surgery.

INTRODUCTION: Nonmedical opioid use is a major public health problem. There is little standardization in opioid-prescribing practices for pediatric ambulatory surgery, which can result in patients being prescribed large quantities of opioids. We have evaluated the variability in postoperative pain medication given to pediatric patients following routine ambulatory pediatric surgical procedures. METHODS: Following IRB approval, pediatric patients undergoing umbilical hernia repair, inguinal hernia repair, hydrocelectomy, and orchiopexy from 2/1/2017 to 2/1/2018 at our tertiary care children's hospital were retrospectively reviewed. Data collected include operation, surgeon, resident or fellow involvement, utilization of preoperative analgesia, opioid prescription on discharge, and patient follow-up. RESULTS: Of 329 patients identified, opioids were prescribed on discharge to 37.4% of patients (66.3% of umbilical hernia repairs, 20.6% of laparoscopic inguinal hernia repairs, and 33.3% of open inguinal hernia repairs [including hydrocelectomies and orchiopexies]). For each procedure, there was large intrasurgeon and intersurgeon variability in the number of opioid doses prescribed. Opioid prescription ranged from 0 to 33 doses for umbilical hernia repairs, 0 to 24 doses for laparoscopic inguinal repairs, and 0 to 20 doses prescribed for open inguinal repairs, hydrocelectomies, and orchiopexies. Pediatric surgical fellows were less likely to discharge a patient with an opioid prescription than surgical resident prescribers (P < 0.01). In addition, surgical residents were more likely to prescribe more than twelve doses of opioids than pediatric surgical fellows (P < 0.01). Increasing patient age was associated with an increased likelihood of opioid prescription (P < 0.01). There were two phone calls and two clinic visits for pain control issues with equal numbers for those with and without opioid prescriptions. CONCLUSIONS: There is significant variation in opioid-prescribing practices after pediatric surgical procedures; increased awareness may help minimize this variability and reduce overprescribing. Training level has an impact on the frequency and quantity of opioids prescribed.

Surgery for no palpable testis before the age of one year: a risk for the testis?

INTRODUCTION: Surgery for undescended testis is now commonly recommended before the age of one year. However, the risk of testicular atrophy or miss location after surgery at a young age has not been clearly evaluated. OBJECTIVE: The objective of this study is to evaluate the rate of testicular atrophy after surgery for non-palpable testis before the age of one year. MATERIALS: Fifty-five patients operated between 2005 and 2014 for non-palpable testes were reviewed for clinical and ultrasound (US) evaluation. Median follow-up after surgery was of 68.5 months (range 26-130 months). The median age at surgery was of months (5-12 months). Eight patients (14.5%) had bilateral non-palpable testis; thus, 63 testes were evaluated. At surgery, 38 (60%) testes were located in the high inguinal canal; 25 (40%), in the abdominal cavity. Orchiopexy was performed with preservation of the testicular vessels for 58 testes. Fowler-Stephens (FS) procedure was performed for 5 testes. Testicular location was clinically evaluated, and testicular volume was measured using a standard sonogram technique in our pediatric radiology department. Ratio comparing the volume of the descended testis to the spontaneously scrotal located testis was calculated in unilateral forms. RESULTS: After surgery, testes had scrotal location in 62 cases and inguinal location in one case. Seven cases of atrophy were confirmed after US control (11%), more frequently (odds ratio, OR 11.68 [1.9-72.5]) in abdominal testis (24%) than in inguinal testis (2.6%). Atrophy testicular was more frequent with FS technique (OR 7.1 [1.3-40.1]), but the population was weak (N = 5). Median volume ratio for unilateral form was 0.88 [0-1.8]; 14 patients presented a ratio greater than 1. DISCUSSION: The influence of the young age at surgery and the risk of post operative testicular atrophy had not been clearly evaluated. The term of 'no palpable testis' supports an heterogeneous group mixing abdominal and extra-abdominal testis sharing a uniform clinical presentation. Our rate of atrophy in the group of abdominal testes (24%) and inguinal testes (2.6%) is similar to the literature, which concerns older patients. The long-term sonogram assessment demonstrated a good development of the testis after surgery, especially in inguinal cases. CONCLUSION: Surgery for no palpable testis before the age of one year does not lead to a superior risk of testicular atrophy compared with surgery at an older age and allows a good development of the testis.

Testicular Volume Changes in Laparoscopic Staged Fowler-Stephens Orchiopexy: Studying the Impact of Testicular Vessel Division.

OBJECTIVE: To study the effect of testicular vessel division on testicular volume during laparoscopic staged Fowler Stephens orchiopexy (LSFSO). METHODS: Testicular dimensions were prospectively measured intraoperatively at both first (S1) and second stages (S2) of LSFSO, and with scrotal ultrasound 3-12 months postoperatively. Testicular volumes were compared to reference ranges. Volume changes were tracked with a change of >20% considered clinically significant. RESULTS: A total of 52 nonpalpable testes treated with LSFSO between 2008 and 2018 were included in the study. After a median follow-up of 6.8 (3-91.3) months, 46 (88.5%) testes were palpable in a scrotal location without adjunctive procedures and 39 (75%) maintained vascular flow on duplex ultrasound. One testis retracted to an inguinal position and was successfully treated with inguinal orchiopexy for an overall success of 90.4% (47/52). Of 36 testes with intra- and postoperative testicular volume documentation, only 2 (5.6%) had significant volume loss after S1. Both testes had catch-up growth after S2. Eight (22.2%) testes had significant volume loss after S2. At follow-up, 24 (66.7%) testes were smaller than the mean for age, of which 20 (83.3%) were small at baseline. Only 41.7% of testes larger than mean for age at follow-up, were small at baseline (P = .02). CONCLUSION: Significant testicular volume loss does not occur after testicular vessel division at S1, but expected in approximately 1 quarter of testes after S2. We propose that testicular atrophy after LSFSO is primarily due to defective testicular development and rarely due to vascular compromise during S2.

Sperm agglutination: Prevalence and contributory factors.

Agglutination is a finding noted in semen analyses (SAs) that often causes confusion as to its significance. While some have attributed agglutination to antisperm antibodies (ASAs), there are other causes as well, such as genital tract infection and ascorbic acid deficiency. Additionally, it is known that patients with ASAs often have risk factors such as a history of scrotal trauma or surgery. Therefore, we sought to determine the prevalence of agglutination in our patient population and correlate it with these risk factors, regardless of the presence/absence of ASAs. A retrospective study was conducted on the SAs of men seen at a single academic Reproductive Center. Of the 1,095 SAs identified, 133 (12.1%) patients experienced agglutination (61.7% scant, 21.8% moderate and 16.5% excessive). Of patients who underwent multiple SAs, 24 (12.2%) showed variability. Furthermore, patients who underwent scrotal surgery carried 3.4 times the risk of agglutination (X2 p < 0.01) and 5.5 times the risk of variability (X2 p < 0.01) as compared to those patients without a history significant for scrotal surgery. Agglutination is a relatively common finding in men presenting to a reproductive clinic with little intrapatient variability. Scrotal surgery confers a higher risk of agglutination and variability.

Fertility in males after childhood, adolescent, and adult inguinal operations.

BACKGROUND/PURPOSE: Inguinal hernia repair and orchidopexy are among the most common operations in boys. The impact on future fertility has not been conclusively defined. This study evaluates sperm quality after previous inguinal surgery. METHODS: Spermiograms of men with a desire to conceive children were analyzed. History of previous inguinal surgery (hernia repair, orchidopexy, varicocele ligation) was correlated with sperm quality. Other influential factors (age, BMI, chronic medication, tobacco use) were also tested. RESULTS: A total of 333 patients were included. Overall, 12.6% of the subjects had undergone previous inguinal surgery. Of these, 17 (43%) were inguinal hernia repairs, 8 (20%) orchidopexies, and 6 (15%) varicocele ligations, while 9 (22%) could not give an exact history. Abnormal spermiograms were found in 60% (n = 24) of those with previous inguinal surgery versus 48% in controls (p = 0.16). On multivariate analysis, pathologic spermiogram parameters were associated with previous inguinal surgery, orchidopexy, use of chronic medication, and smoking, but NOT with inguinal hernia or varicocele repair alone. CONCLUSIONS: Previous inguinal hernia or varicocele repair does not seem to impact negatively on quality of sperm later in life. Orchidopexy, smoking, and use of chronic medication, however, were all associated with pathologic sperm quality parameters. TYPE OF STUDY: Prospective comparative study. LEVEL OF EVIDENCE: Level II.

Bilateral orchidopexies: synchronous or metachronous? Survey of BAPS and BAPU members and single-centre comparison.

BACKGROUND/AIM: Approximately 20% of undescended testes (UDT) are bilateral. It is unclear whether bilateral orchidopexy (BO) should be undertaken synchronously (SBO) or metachronously (MBO). Our aim was to investigate current UK practice and the complications of SBO vs MBO. MATERIALS & METHODS: Following approval of BAPS and BAPU ethics committee, a survey was circulated to UK consultant pediatric surgeons and urologists regarding practice. A departmental retrospective review was additionally carried out for patients undergoing BO between 2005 and 2017. RESULTS: Forty-three consultant surgeons from 20 centres completed the survey. Overall, SBO was preferred by 70% for bilateral palpable UDT versus 30% for bilateral impalpable UDT. When one side was palpable and the other impalpable, 70% preferred SBO. Pediatric urologists were significantly more likely to undertake SBO than pediatric general surgeons. One hundred eighty-eight patients (376 testicular units) were identified who had undergone BO with a median follow up of 9 months. 144/188 (76.6%) underwent SBO, while 44 had MBO. There was no statistical difference in the complication rate between the two groups (7.6% in SBO vs 9.1% in MBO; p = 0.66). CONCLUSIONS: The majority of the responding UK consultants, in particular pediatric urologists, favor SBO. This potentially offers a reduction in cost, more rapid completion of treatment, and is not associated with additional complications by comparison to MBO. We recommend SBO to be standard practice for bilateral UDT whenever possible. LEVEL OF EVIDENCE: Level III, Retrospective Comparative Study.

Evaluation of Fowler-Stephens orchiopexy for high-level intra-abdominal cryptorchidism: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: There has been no consensus regarding the best surgical strategy for patients with cryptorchidism involving high-level intra-abdominal testes. This systematic review and meta-analysis compared the outcomes of Fowler-Stephens orchiopexy (FSO) conducted as 1-stage or 2-stage, open or laparoscopic. METHODS: The databases PubMed, Cochrane Library, Web of Science Database, Russian Science Citation Index, SciELO Citation Index, China National Knowledge Infrastructure, WanFang Data, and China Biology Medical disc were systematically searched for relevant articles. RESULTS: Sixty studies involving 1991 operated testes were included in the final analysis. The overall success rates for 1- and 2-stage FSOs were 85% and 87%, respectively; overall atrophy rates for both were 10%. The success rates of 1-stage FSOs, open and laparoscopic, were 83% and 87%; with atrophy rates of 12% and 8%. The corresponding success rates of 2-stage FSOs were 81% and 89%; with atrophy rates of 17% and 8%. The odds ratios indicated that 2-stage FSO was significantly superior to 1-stage, and laparoscopic superior to open. Evaluating laparoscopic FSO over time, the success rates prior to year 2000, 2000 through 2010, and after 2010 were 85%, 89%, and 88%, and atrophy rates were 15%, 9%, and 6%, with no heterogeneity in the reports, and the funnel plot showed no publication bias. CONCLUSION: Each surgical technique for correcting high-level intra-abdominal testes (IATs) had an acceptable success rate, from 81% to 89%. However, in terms of highest success rate and lowest atrophy rate, 2-stage laparoscopic FSO is the first choice for treating high intra-abdominal cryptorchidism.

Prospective Evaluation of Predictors of Testis Atrophy After Surgery for Testis Torsion in Children.

OBJECTIVE: To prospectively correlate pain duration, red scrotal skin, ultrasound appearance of testis, and intraoperative testis color to future testis atrophy after acute testicular torsion. METHODS: Patients 2 months-18 years old with unilateral acute scrotum were consecutively enrolled in a National Institutes of Health transcutaneous near-infrared spectroscopy study, with a subgroup analysis of the true torsion group. Presence or absence of red scrotal skin, pain duration, testicular heterogeneity on preoperative ultrasound, and intraoperative testis color based on a novel visual chart 5 minutes after detorsion were recorded. All testes underwent orchiopexy regardless of appearance. Percent volume difference between normal and torsed testicles on follow-up ultrasound was compared between patients with and without risk factors. RESULTS: Thirty of 56 patients who had surgical detorsion underwent scrotal ultrasound at a mean of 117 days after surgery. A color of black or hemorrhagic 5 minutes after detorsion, pain duration >12 hours, and heterogeneous parenchyma on preoperative ultrasound were associated with significant testis volume loss in follow-up compared with normal testis. All patients with a black or hemorrhagic testis had >80% volume loss. Erythematous scrotal skin was not significantly associated with smaller affected testis volume in follow-up. CONCLUSION: Based on the high atrophy rate, orchiectomy can be considered for testes that are black or hemorrhagic 5 minutes after detorsion. Pain duration >12 hours and parenchymal heterogeneity on preoperative ultrasound were also associated with testis atrophy. Red scrotal skin was not a reliable predictor of atrophy and should not delay exploration.
