Comparison of Single-Incision Scrotal Orchiopexy and Traditional Two-Incision Inguinal Orchiopexy for Primary Palpable Undescended Testis in Children: A Systematic Review and Meta-Analysis

Comparison of scrotal and inguinal orchiopexy for palpable undescended testis: a meta-analysis of randomized controlled trials

INTRODUCTION

Scrotal and inguinal orchiopexy are two commonly used surgical approaches for palpable undescended testis (UDT), each with distinct advantages. However, the optimal approach remains a matter of debate, warranting a comprehensive meta-analysis of randomized controlled trials (RCTs) to guide clinical decision-making.

MATERIALS AND METHODS

A comprehensive literature search was conducted, adhering to PRISMA guidelines, to select RCTs comparing scrotal and inguinal orchiopexy for palpable UDT. Eight RCTs were selected for meta-analysis. Outcome measures included operative time, hospitalization duration, total complications, wound infection or dehiscence, testicular atrophy or hypotrophy, and testicular re-ascent rate. The evaluation of the study's quality was conducted by utilizing the revised Cochrane risk-of-bias tool.

RESULTS

Scrotal orchiopexy showed significantly shorter operative time compared to the inguinal approach (WMD: - 15.06 min; 95% CI: - 21.04 to - 9.08). However, there was no significant difference in hospitalization duration (WMD: - 0.72 days; 95% CI: - 1.89-0.45), total complications (OR: 1.08; 95% CI: 0.70-1.66), wound infection or dehiscence (OR: 0.73; 95% CI: 0.27-1.99), testicular atrophy or hypotrophy (OR: 1.03; 95% CI: 0.38-2.78), and testicular re-ascent (OR: 1.43; 95% CI: 0.67-3.06) between the two approaches. A small proportion of cases (7.3%) required conversion from scrotal to inguinal orchiopexy due to specific anatomical challenges.

CONCLUSION

Both scrotal and inguinal orchiopexy are safe and effective for palpable UDT, with comparable outcomes in terms of hospitalization and complications. Scrotal orchiopexy offers the advantage of shorter operative time. Clinicians can use this evidence to make informed decisions on the surgical approach for palpable UDT.

Surgical treatment of cryptorchidism: current insights and future directions

Cryptorchidism presents with an incidence of 1-5% with potential long-term implications on future fertility and overall health. This review focuses on surgical treatment modalities, their impact on testicular development, and function while addressing the Nordic consensus statement as well as current European Association of Urology (EAU) and American Urological Association (AUA) guidelines. Congenital and acquired cryptorchidism present distinctive challenges in surgical management, with different implications for fertility. While congenital cryptorchidism entails a risk to fertility and warrants early intervention, both retractile testes and acquired cryptorchidism also pose risks to fertility potential, underscoring the importance of evaluating treatment options. Testicular location and the child's age form the basis of a practical classification system for undescended testicles. Early diagnosis by clinical examination enables timely treatment. Imaging is reserved for selected cases only. Following guidelines, orchidopexy is recommended between 6-12 months of age for congenital cryptorchidism. Evidence increasingly suggests the benefits of early surgery for promoting testicular health and fertility potential. Current surgical options range from open to laparoscopic techniques, with the choice largely determined by the location and accessibility of the undescended testicle. The advancement in laparoscopic approaches for non-palpable testes underscores the evolving landscape of surgical treatment. Sequential surgeries may be required depending on the mobility of the undescended testes. More research is needed to explore both the potential and limitations of hormonal therapy, which is secondary to surgical treatment and can selectively have a role as adjunct to surgery. Long-term follow-up is imperative to evaluate fertility outcomes, risk of testicular malignancy, and psychological impact. By integrating current guidelines with the latest evidence, this review intends to facilitate a comprehensive understanding of cryptorchidism, thereby optimizing patient management and outcomes.

Undescended testis: A roundtable discussion based on clinical scenarios - Part 1

Undescended testis (UDT, cryptorchidism) is the most common congenital anomaly of the genital tract. Despite its high incidence, the management of UDT varies between specialties (urology, pediatric surgery, pediatric urology, pediatric endocrinology). Therefore, as the European Association of Urology - Young Academic Urologists Pediatric Urology Working Group, we requested experts around the world to express their own personal approaches against various case scenarios of UDT in order to explore their individual reasoning. We intended to broaden the perspectives of our colleagues who deal with the treatment of this frequent genital malformation.

Diagnosis, Classification, and Contemporary Management of Undescended Testicles

This article provides a comprehensive review regarding undescended testicles and other related conditions. We have included background information summarizing variable clinical presentations, epidemiology, and the implications of undescended testis (UDT) on fertility and malignancy risk. This article has an emphasis on the approach to diagnosis and surgical management for the UDT. The purpose of this review is to provide readers with useful clinical tools for assessing and treating patients with cryptorchidism.

Laparoscopic assisted trans-scrotal orchiopexy versus traditional orchiopexy for inguinal cryptorchidism: a retrospective study based on 154 patients

BACKGROUND

The purpose of this study was to investigate the clinical effect of laparoscopic assisted trans-scrotal orchiopexy versus traditional orchiopexy for inguinal cryptorchidism.

METHODS

A retrospective analysis of cryptorchidism patients who were admitted to our hospital from July 2018 to July 2021. The patients were divided into the laparoscopic assisted trans-scrotal surgery group (n = 76) and the traditional surgery group (n = 78) according to the surgical method.

RESULTS

All patients were successfully operated. There was no significant difference in operation time between the laparoscopic assisted trans-scrotal group and the traditional group (P>0.05). Although there was no significant difference in the postoperative hospital stay between the two groups, the time of postoperative hospital stay of the laparoscopic assisted trans-scrotal surgery group was lower than that in the traditional surgery group (P = 0.062). Additionally, there was no significant difference in discharge rate on the first day after surgery between the two groups, but the discharge rate on the first day after surgery was more than 90% in both groups. In terms of postoperative complications, there were no cases of testicular retraction, testicular atrophy, inguinal hernia, or hydrocele that occurred in both groups. There was no significant difference in the incidence of scrotal hematoma between the two groups(P>0.05). Although there was no significant difference in the incidence of poor wound healing between the two groups(P>0.05), the incidence in the laparoscopic assisted trans-scrotal surgery group was lower than that in the traditional surgery group (2.6% vs. 6.4%).

CONCLUSION

Laparoscopic assisted trans-scrotal surgery is as safe and effective method as traditional surgery for patients with inguinal cryptorchidism, and could also provide a good appearance.

Open controversies on the treatment of undescended testis: An update

Cryptorchidism is a common congenital malformation in pediatric urology. Although there have been many studies on the etiology of the disease, it has not been fully clarified, and while its diagnostic and treatment models have gradually approached standardization and systematization, some controversies regarding treatment remain. Additionally, although ultrasound is a non-invasive examination without ionizing radiation, its role in the evaluation of cryptorchidism remains controversial. The main basis for treating cryptorchidism is orchidopexy, and the main view on treatment age is that treatment should be performed between 6 and 12 months after birth, but no more than 18 months after birth. The view on hormone therapy is still controversial because most scholars believe that early surgery is the key to treatment. There are many surgical treatment methods for cryptorchidism, including traditional open surgery and laparoscopic surgery, which provide satisfactory results. In conclusion, the treatment of undescended testis (UDT) had been largely standardized, apart from the treatment of high intra-abdominal testis (IAT), which remains a matter of debate.
