Management of the undescended testis in children: An American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee Systematic Review. J Pediatr Surg 2022; 57:1293-1308. [PMID: 35151498 DOI: 10.1016/j.jpedsurg.2022.01.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2021] [Revised: 12/31/2021] [Accepted: 01/08/2022] [Indexed: 01/03/2023]
Abstract
PURPOSE Management of undescended testes (UDT) has evolved over the last decade. While urologic societies in the United States and Europe have established some guidelines for care, management by North American pediatric surgeons remains variable. The aim of this systematic review is to evaluate the published evidence regarding the treatment of (UDT) in children. METHODS A comprehensive search strategy and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were utilized to identify, review, and report salient articles. Five principal questions were asked regarding imaging standards, medical treatment, surgical technique, timing of operation, and outcomes. A literature search was performed from 2005 to 2020. RESULTS A total of 825 articles were identified in the initial search, and 260 were included in the final review. CONCLUSIONS Pre-operative imaging and hormonal therapy are generally not recommended except in specific circumstances. Testicular growth and potential for fertility improves when orchiopexy is performed before one year of age. For a palpable testis, a single incision approach is preferred over a two-incision orchiopexy. Laparoscopic orchiopexy is associated with a slightly lower testicular atrophy rate but a higher rate of long-term testicular retraction. One and two-stage Fowler-Stephens orchiopexy have similar rates of testicular atrophy and retraction. There is a higher relative risk of testicular cancer in UDT which may be lessened by pre-pubertal orchiopexy.

Abstract
PURPOSE OF REVIEW The two-stage Fowler-Stephens orchiopexy is a well-described surgical approach for most pediatric urologists tackling the high intra-abdominal testis. Testicular ascent is a well-reported outcome of the surgery and a problem that could be fixed with a repeat procedure. The purpose of this review is to determine the rate of subsequent testicular ascent and repeat surgery after a two-stage Fowler-Stephens using best available evidence. RECENT FINDINGS/RESULT We selected 16 studies that pertained to our topic. 0-13% of testicles were deemed to be in an inappropriate position on follow-up (6-37 months). The definition of appropriate postoperative position varied between studies and rates of repeat procedures were sparsely available. Available data reports a repeat orchiopexy rate of 2.6-7.5% after two-stage Fowler-Stephens. Two-stage Fowler-Stephens orchiopexy is a highly successful surgical technique to manage high intra-abdominal testes. Rates of testicular ascent are difficult to ascertain due to varying definitions and small sample sizes. While repeat procedures are typically indicated, the actual rate of repeat orchiopexy is rarely reported and long-term outcomes following a third procedure is sparse.

J Pediatr Urol 2020; 16:197.e1-197.e7. [PMID: 32085874 DOI: 10.1016/j.jpurol.2020.01.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2019] [Accepted: 01/07/2020] [Indexed: 02/06/2023]
Abstract
OBJECTIVE The aim of the study was to compare the outcome of the prospective cohort who had one-stage laparoscopic Fowler-Stephens orchiopexy (LFSO) with an earlier, similar cohort who had a two-stage LFSO. Both cohorts included only intra-abdominal testes (IATs) with short spermatic vessels. STUDY DESIGN The present study initially included all patients between the age of six months and preschool age, presenting with an IAT to the authors' tertiary clinic from January 2012 to December 2014. Only intra-abdominal testes with short testicular vessels, correlating to type 3A, 3B and 4A as per the updated Ain Shams classification, were included in this study. One-stage LFSO was performed on all patients. Patients with bilateral intra-abdominal testes had the procedure performed on the contralateral side 6-8 weeks later. Follow-up was performed at 6, 12 and 36 months postoperatively by means of Doppler ultrasound in the first two visits. A similar subgroup of the historical cohort from years 2002 to 2010 had a two-stage LFSO, with the second stage being performed 12-16 weeks later. In bilateral cases, a three-interval surgery based on two-stage LFSO was performed, with a follow-up at 6 months postoperatively. RESULTS The recent cohort included 16 IATs (10 unilateral and 3 bilateral). The median age of the patients was 1.41 years. At 6-month follow-up, 4 testes were found atrophic (25%), whereas the remaining 12 testes (75%) were viable. In those viable, only half of them had a low scrotal position. No difference was found at 12- or 36-month follow-up. Doppler ultrasound confirmed adequate intratesticular blood flow at 6 and 12 months postoperatively. In the similar subgroup of the historical cohort, 3 of 25 (12%) testes were found atrophied at six months postoperatively, with only one testis (4%) having a high scrotal position. In a comparison of both cohorts, the two-stage LFSO was found to be associated with a halving of the testicular atrophy rate (p value = 0.401) and a higher incidence of low scrotal position (p value = 0.004). A comparison of both cohorts is shown in the summary table. CONCLUSION Although one-stage LFSO may seem tempting, it still holds a higher rate of testicular atrophy, which is not justified. LEVEL OF EVIDENCE Level III (Case-control study).

Abstract
BACKGROUND The purpose of this study was to estimate the unmet burden of surgically correctable congenital anomalies in African low- and middle-income countries (LMICs). METHODS We conducted a chart review of children operated for cryptorchidism, isolated cleft lip, hypospadias, bladder exstrophy and anorectal malformation at an Ethiopian referral hospital between January 2012 and July 2016 and a scoping review of the literature describing the management of congenital anomalies in African LMICs. Procedure numbers and age at surgery were collected to estimate mean surgical delays by country and extrapolate surgical backlog. The unmet surgical need was derived from incidence-based disease estimates, established disability weights, and actual surgical volumes. RESULTS The chart review yielded 210 procedures in 207 patients from Ethiopia. The scoping review generated 42 data sets, extracted from 36 publications, encompassing: Benin, Egypt, Ghana, Ivory Coast, Kenya, Nigeria, Madagascar, Malawi, Togo, Uganda, Zambia, and Zimbabwe. The largest national surgical backlog was noted in Nigeria for cryptorchidism (209,260 cases) and cleft lip (4154 cases), and Ethiopia for hypospadias (20,188 cases), bladder exstrophy (575 cases) and anorectal malformation (1349 cases). CONCLUSION These data support the need for upscaling pediatric surgical capacity in LMICs to address the significant surgical delay, surgical backlog, and unmet prevalent need.

Abstract
INTRODUCTION The best operative intervention for intrabdominal testis (IAT) has not been standardized as yet. The question of whether to bring down an IAT with a single-staged vessel-intact laparoscopic orchidopexy (VILO) or a two-staged laparoscopic Fowler-Stephens orchidopexy (FSLO) is still undergoing debate, with both the procedures being popular. The present study has been designed to evaluate the factors predicting the success or failure of two-staged FSLO for (IAT). METHODS 43 boys with 49 non-palpable testes underwent diagnostic laparoscopy out of which 35 underwent two-staged FSLO. Size of the testis was measured with a graduated probe in both stages. Independent variables such as age, height, testis-to-internal ring distance (T-IR), neo internal ring-to-midscrotal distance (NIR-MS), and mobility-to-contralateral ring (MCIR) were analysed. Postoperatively 34 IATs were followed up clinically as well as ultrasonologically after 6 months, to see for the size, position, and vascularity. Based on this, the patients were divided into two groups, Group A (successful) and Group B (Failed). RESULTS 24 IATs had a successful outcome (Group A) and 11 were failure (Group B). The overall success rate of the study was 68.6%. The difference in mean age of patients in both groups was insignificant (p = 0.89) (Fig. 1), and similarly, the difference in mean height was insignificant (p = 0.61). The difference in mean T-IR in both the groups was insignificant (1.85 versus 2.77 cm; p = 0.09) and mean NIR-MS was 5.41 cm in Group A and 5.10 cm in Group B, and the difference again was insignificant (p = 0.23). CONCLUSION The success rate of FSLO was 68.6%. None of the above-described independent variables have any effect on the outcome of two-staged FSLO. While VILO remains the treatment of choice for IAT located at or near the ring, but IAT higher than this, two-staged FSLO gives a better chance for achieving intra-scrotal orchidopexy.

Abstract
Cryptorchidism is one of the most common congenital anomalies in males, characterized by inability to palpate the testicle in the expected normal anatomical position (i.e., within its respective hemi-scrotum). It represents an abnormality of testicular descent and development associated with long-term concerns, including infertility, hypogonadism, and development of neoplasms.

Abstract
PURPOSE While the nonpalpable testis represents a small portion of all cryptorchid testes, it remains a clinical challenge for pediatric urologists. Controversy exists surrounding the best evaluation and management of this entity. In this review we update what is known about the nonpalpable testis, including the etiology, preoperative evaluation and best surgical management as well as novel techniques and ongoing controversies. MATERIALS AND METHODS We searched PubMed® and MEDLINE® from January 2000 to January 2017 using relevant key terms. Of 367 articles 115 were considered for inclusion based on a priori design. Using a narrative review format, an update on the evaluation and management of the nonpalpable testis including novel concepts and techniques was synthesized. RESULTS The nonpalpable testis should be evaluated by physical examination only. Imaging is not indicated for routine cases. The optimal surgical approach and technique remain debatable but several novel techniques have been described. Due to the rarity of the nonpalpable testis, randomized controlled trials and other quality comparisons are difficult. Therefore, management remains controversial. CONCLUSIONS Evaluation and management of the nonpalpable testis remain difficult, and some aspects are still debated. Future research should focus on multi-institutional collaborative trials to determine the optimal operative management.

Abstract
PURPOSE The aims of the study were to study the effect of Fowler-Stephens orchiopexy (FSO) on testicular histology and to assess the feasibility of using monopolar diathermy as an alternative to clip ligation during laparoscopic FSO. PATIENTS AND METHODS The study included 20 patients with 20 intraabdominal testes and short vessels managed by laparoscopic-staged FSO. Biopsies were taken from intraabdominal testes during the first and second stages of the procedure for histologic comparison. The patients in the study were divided into 2 groups according to the method of dividing the testicular vessels in stage 1. The first 13 patients (group A) were managed by clip ligation of the vessels, whereas monopolar diathermy was used in the following 7 patients (group B). RESULTS Biopsy findings at stage 2 revealed an overall reduction in both the total number of germ cells per tubule and mean diameter of seminiferous tubules, whereas there was no statistically significant difference between the results in groups A and B. CONCLUSION The seminiferous cells can withstand (survive) dividing the main blood supply of the testis during FSO. The monopolar diathermy can be used as an alternative to clipping during laparoscopic procedures, having the advantages of lower expenses and using smaller instruments.

Abstract
PURPOSE There is a paucity of literature on factors associated with testicular atrophy following second stage laparoscopic Fowler-Stephens orchiopexy. We hypothesized that dissection of a long looping vas during this procedure could compromise testicular blood supply, leading to testicular atrophy. MATERIALS AND METHODS Following an initial laparoscopic testicular vessel ligation, a second stage Fowler-Stephens orchiopexy was performed in 73 testes (laparoscopic in 61, open in 12). The presence of a long looping vas was noted from the first stage operative notes. Doppler ultrasound was performed postoperatively to confirm testicular atrophy. RESULTS Atrophy rate at a mean followup of 13.5 months was 20.5% (15 of 61 in laparoscopic and 0 of 12 in open orchiopexy). None of the 5 long looping vas testes atrophied following open orchiopexy, compared to 5 of 6 (83%) following laparoscopic orchiopexy (p = 0.03). Analyzing the laparoscopic group alone, a long looping vas was significantly associated with risk of atrophy (p <0.01). CONCLUSIONS The presence of a long looping vas was associated with a higher atrophy rate following laparoscopic second stage Fowler-Stephens orchiopexy. Laparoscopic management of the long looping vas may be more challenging and, therefore, in such cases open Fowler-Stephens orchiopexy may result in better success rates by preserving the integrity of the collateral vessels.
