The aim of this study was to investigate the trend in testicular volume changes after orchiopexy in children with cryptorchidism. The clinical data of 854 children with cryptorchidism who underwent orchiopexy between January 2013 and December 2016 in Shenzhen Children's Hospital (Shenzhen, China) were retrospectively analyzed. The mean (standard deviation) age of the patients was 2.8 (2.5) years, and the duration of follow-up ranged from 1 year to 5 years. Ultrasonography was conducted preoperatively and postoperatively. The variables analyzed included age at the time of surgery, type of surgical procedure, laterality, preoperative testicular position, preoperative and postoperative testicular volumes, and the testicular volume ratio of them. The average testicular volumes preoperatively and at 1 year, 2 years, 3 years, and 5 years postoperatively were 0.27 ml, 0.38 ml, 0.53 ml, 0.87 ml, and 1.00 ml, respectively ( P < 0.001). The corresponding testicular volume ratios were 0.67, 0.76, 0.80, 0.83, and 0.84 ( P < 0.001). The mean volume of the undescended testes was significantly smaller than the mean normative value ( P < 0.001, lower than the 10 th percentile). The postoperative testicular volumes in children with cryptorchidism were generally lower than those in healthy boys but were still greater than the 10 th percentile and exhibited an increasing trend. The older the child is at the time of surgery, the larger the gap in volume between the affected and normal testes. Although testicular volume tends to gradually increase after orchiopexy for cryptorchidism, it could not normalizes. Earlier surgery results in affected testicular volumes closer to those of healthy boys.

This study assessed the feasibility of testis tissue cryopreservation (TTC) for fertility preservation in prepubescent boys with cryptorchidism. From January 2014 to December 2022, the University Hospital of Copenhagen (Rigshospitalet, Copenhagen, Denmark) implemented TTC for 56 boys with cryptorchidism to preserve their reproductive potential. Testis tissue samples were collected during orchiopexy (32 cases) or at subsequent follow-up procedures (24 cases), necessitated by an increased risk of infertility as indicated by hormonal assessments and/or findings from initial surgical biopsies. Testis samples were procured for TTC and pathological analysis. The cohort had an average age of 1.3 (range: 0.3-3.8) years at the time of orchiopexy, with 91.1% presenting bilateral cryptorchidism. The study revealed a median germ cell count of 0.39 (range: 0-2.88) per seminiferous tubule, with germ cells detected in 98.0% of the bilateral biopsies and 100% of the unilateral, indicating a substantial potential for fertility in these immature tissues. A dark spermatogonia (Ad) was detected in 37 out of 56 patients evaluated, with a median Ad spermatogonia count of 0.027 (range: 0.002-0.158) per seminiferous tubule. A total of 30.2% of the samples lacked Ad spermatogonia, indicative of potential gonadotrophin insufficiency. The median hormone levels measured were as follows: follicle-stimulating hormone (FSH) at 0.69 (range: 0.16-2.5) U l -1 , luteinizing hormone (LH) at 0.21 (range: 0.05-3.86) U l -1 , and inhibin B at 126 (range: 17-300) pg ml -1 . Despite early orchiopexy, 20%-25% of boys with cryptorchidism remain at risk for future infertility, substantiating the necessity of TTC as a precaution. The study highlights the need for refined predictive techniques to identify boys at higher risk of future infertility.

To compare the impact of the scrotal vs inguinal orchidopexy approach on the testicular function of infants with cryptorchidism, a randomized controlled trial was conducted involving boys who were 6-12 months old at surgery and were diagnosed with clinically palpable, inguinal undescended testis. Between June 2021 and December 2021, these boys at Fujian Maternity and Child Health Hospital (Fuzhou, China) and Fujian Children's Hospital (Fuzhou, China) were enrolled. Block randomization with a 1:1 allocation ratio was employed. The primary outcome was testicular function assessed by testicular volume, serum testosterone, anti-Müllerian hormone (AMH), and inhibin B (InhB) levels. Secondary outcomes included operative time, amount of intraoperative bleeding, and postoperative complications. Among 577 screened patients, 100 (17.3%) were considered eligible and enrolled in the study. Of the 100 children who completed the 1-year follow-up, 50 underwent scrotal orchidopexy and 50 underwent inguinal orchidopexy. The testicular volume, serum testosterone, AMH, and InhB levels in both groups increased markedly after surgery (all P < 0.05), but there were no apparent differences between groups at 6 months and 12 months after operation (all P > 0.05). No differences between the scrotal and inguinal groups were noted regarding the operative time ( P = 0.987) and amount of intraoperative bleeding ( P = 0.746). The overall complication rate (2.0%) of the scrotal group was slightly lower than that of the inguinal group (8.0%), although this difference was not statistically significant ( P > 0.05). Both scrotal and inguinal orchiopexy exerted protective effects on testicular function in children with cryptorchidism, with similar operative status and postoperative complications. Scrotal orchiopexy is an effective alternative to inguinal orchiopexy in children with cryptorchidism.

A retrospective cohort study was conducted at the Children's Hospital of Chongqing Medical University from November 2004 to December 2020 to investigate the long-term follow-up results after testicular torsion (TT) in children. Boys with TT were divided into the salvage orchiopexy group and the orchiectomy group, and the baseline characteristics, ultrasonographic indications, intraoperative findings, testicular volumes, and adverse events during follow-up were compared. A total of 145 cases were included in this study. Approximately 56.6% of patients who underwent salvage orchiopexy had testicular atrophy (TA), and the median testicular volume loss of the testes was 57.4%. Age less than 6 years, delayed surgery, and intraoperative poor blood supply were associated with TA in pediatric TT after orchiopexy. Most atrophied testes appeared within 3-6 months after surgery. Compared with the corresponding age-matched healthy controls, the contralateral testicular volumes were larger in the orchiopexy (P = 0.001 without TA, and P = 0.042 with TA) and orchiectomy groups (P = 0.033). The adverse events were comparable in patients with orchiectomy or orchiopexy. In summary, follow-up before 3 months after surgery may not offer sufficient clinical value, while that 3 months after surgery should be regarded as the first follow-up time for testicular monitoring. The contralateral testes of patients with TT showed compensatory hypertrophy. We suggest performing orchiectomy when torsed testes are surgically assessed as Arda grade III or inviable.

Non-obstructive azoospermia (NOA), which is defined as the absence of spermatozoa in the ejaculate secondary to impaired spermatogenesis within the testis, may be caused by a variety of etiologies, including varicocele-induced testicular damage, cryptorchidism, prior testicular torsion, post-pubertal mumps orchitis, gonadotoxic effects from medications, genetic abnormalities, chemotherapy/radiation, and other unknown causes currently classified as idiopathic (Cocuzza et al., 2013). The microdissection testicular sperm extraction (micro-TESE) technique involves a meticulous microsurgical exploration of the testicular parenchyma to identify and selectively extract larger seminiferous tubules that carry a higher probability of complete spermatogenesis (Schlegel, 1999). The Cornell group evaluated the efficacy of micro-TESE in 152 NOA patients with an associated history of cryptorchidism. In their series, spermatozoa were successfully retrieved in 116/181 attempts (64%), and the resulting pregnancy rate was 50% with a delivery rate of 38% (Dabaja and Schlegel, 2013). Franco et al. (2016) described a stepwise micro-TESE approach in NOA patients, which was considered to reduce the cost, time, and effort associated with the surgery. Alrabeeah et al. (2016) further reported that a mini-incision micro-TESE, carried through a 1-cm equatorial testicular incision, can be useful for micro-TESE candidates, particularly in patients with cryptozoospermia. We conducted a retrospective study of 20 consecutive NOA patients with a history of orchidopexy from May 2015 to March 2017.

We investigated the associations of clinical and socioeconomic factors with delayed orchidopexy for cryptorchidism in China. A retrospective study was conducted on cryptorchid boys who underwent orchidopexy at Children's Hospital at Chongqing Medical University in China from January 2012 to December 2017. Of 2423 patients, 410 (16.9%) received timely repair by 18 months of age, beyond which surgery was considered delayed. Univariate analysis suggested that the laterality of cryptorchidism (P = 0.001), comorbidities including inguinal hernia/scrotal hydrocele (P < 0.001) or urinary tract disease (P = 0.016), and whether patients lived in a poverty county (P < 0.001) could influence whether orchidopexy was timely or delayed. Logistic regression analysis suggested that the following factors were associated with delayed repair: unilateral rather than bilateral cryptorchidism (odds ratio [OR] = 1.752, P < 0.001), absence of inguinal hernia or hydrocele (OR = 2.027, P = 0.019), absence of urinary tract disease (OR = 3.712, P < 0.001), and living in a poverty county (OR = 2.005, P < 0.001). The duration of postoperative hospital stay and hospital costs increased with the patient's age at the time of surgery.

PURPOSE: Though prompt diagnosis to minimize symptom duration (SD) is highly associated with organ salvage in cases of testicular torsion (TT), SD is subjective and hard to determine. We thus investigated the clinical implications of systemic inflammatory responses (SIRs) as potential surrogates of SD to improve testis survival. MATERIALS AND METHODS: Sixty men with TT that underwent immediate operation among orchiectomy and orchiopexy following a visit to a single emergency department were retrospectively enrolled. Mandatory laboratory tests conducted included neutrophil, lymphocyte, and platelet counts. RESULTS: Mean age and SD was 15.7±3.7 years and 8.27±4.98 hours, respectively. Thirty-eight (63.3%) underwent orchiectomy and the remaining 22 underwent orchiopexy. Leukocytosis (p=0.001) and neutrophil-lymphocyte ratio (NLR, p < 0.001) were significantly lower in the orchiopexy group as was SD (3.27±1.88 vs. 11.16±3.80, p < 0.001). Although multivariate model showed that the only single variable associated with receipt of orchiopexy was SD (odds ratio [OR]=0.259, p < 0.001), it also revealed NLR as a sole SIR associated with SD (B=0.894, p < 0.001). While 93.3% with a SD of within 3 hours underwent orchiopexy, only 26.6% of affected testes were preserved between 3 to 12 hours (n=30). When multivariable analysis was applied to those with window period, NLR alone predicted orchiopexy rather than orchiectomy (p=0.034, OR=0.635, p=0.013). The area under curve between SD (0.882) and NLR (0.756) was similar (p=0.14). CONCLUSIONS: This study showed NLR independently predicted testis survival by proper surgical correction particularly for patients with marginally delayed diagnosis, which suggest the clinical usefulness for identifying candidates for orchiopexy in emergency setting.

PURPOSE: Preoperative ultrasonography (USG) in pediatric inguinal hernia has controversy. In this study, we analyzed the cases of pediatric inguinal hernia with/without preoperative USG and discussed whether USG is necessary. METHODS: We reviewed medical records of 1,441 patients who underwent inguinal hernia repair in Seoul National University Children's Hospital between January 2011 and August 2016 retrospectively. RESULTS: Male were 69.3% and age at operation was 37.8±36.5 months old. There were 150 patients (10.4%) performed USG preoperatively. The department ordered to perform USG included department of surgery (n=71), emergency medicine (n=42), pediatrics (n=26), urology (n=10) and outside hospital (n=1). The reasons of performing USG included evaluation for hernia laterality (n=82), incarceration (n=28), testis (n=15), request of parents (n=14), scrotal mass (n=6) and incidentally found during evaluation for another disease (n=5). Excepting 5 cases of incidental finding, of 145 cases with USG, 12 (8.3%) cases changed the surgical plan; change to bilateral repair from unilateral repair (n=5), emergency operation due to incarceration (n=4) which include 1 salpingo-oophorectomy, 1 open abdomen surgery and 2 hernia repair after reduction of ovary, change to co-operation of orchiopexy (n=2) and change to laparoscopic surgery from open surgery due to herniation of both ovaries into one inguinal canal (n=1). In group without USG (n=1,291), 5 patients (0.4%) had unexpected problems during operation; 2 co-operation of orchiopexy because of transverse testicular ectopia (n=1) and right undescended testis (n=1), 2 hypertrophy of major labia and 1 retroperitoneal lymphangioma at inguinal area misdiagnosed as inguinal hernia. CONCLUSION: It was difficult to interpret the meaning of preoperative USG because not all patients had performed it. In this study, 10.4% of patients performed USG and 8.3% of them changed surgical plan. About 0.4% of patients without preoperative USG would have benefited from it for surgery if they had performed it. Since the percentage is too low, it is unreasonable to conclude that USG has diagnostic utility in inguinal hernia in this study.

Objective: To investigate the effect of modified Bianchi (single incision in the midline of the scrotum) orchiopexy (MBO) versus that of traditional surgery in the treatment of median or low cryptorchidism. METHODS: Eighty-two children with median or low cryptorchidism were treated from February 2013 to February 2014, 46 (53 testes) by MBO and the other 36 by the traditional method of inguinal incision (control, 40 testes). Comparisons were made in the operation time and postoperative complications between the two surgical strategies. RESULTS: The mean operation time was significantly shorter in the MBO group than in the control (［25±6］ vs ［35±4］ min, P<0.05). No testicular atrophy, hernias or hydrocele was found in either group during the 1－2 years of follow-up. Testis retraction was observed in 3 cases in the MBO group as compared with 2 in the control (P>0.05). The incision scar was obvious in all the controls, with 1 case of postoperative inguinal hematoma, but almost invisible in all the MBO cases. CONCLUSIONS Modified Bianchi orchiopexy is superior to traditional surgery in the treatment of median or low cryptorchidism for its advantages of short operation time, few complications, and satisfactory appearance of the healed incision.
