Abstract
Background This study performed a systematic review and meta-analysis to compare the outcomes of the staged laparoscopic Fowler-Stephens Laparoscopic Orchiopexy (FSLO) and Staged Laparoscopic Traction Orchiopexy (SLTO) in patients with intra-abdominal testes (IAT). Methods This study reviewed literature published from 2016 to 2024. A systematic literature search was conducted on three databases: PubMed, ScienceDirect, and Google Scholar, using keywords (High intra abdominal testis) AND (("Fowler Stephens laparoscopic orchiopexy" OR (FSLO)) OR (Staged Laparoscopic traction orchiopexy OR (SLTO)). Non-randomized trials and observational studies comparing staged laparoscopic FSLO and SLTO, without any time range restriction are included. Studies without FLSO orchidopexy as a control, case reports, case studies, duplicate publication, no full text and non-English studies are excluded. This study used the PRISMA protocol, the Jadad Scale, and the Newcastle Ottawa Scale (NOS) to evaluate the included studies. To analyze statistical data, the Review Manager (RevMan) software was used. The Chi-squared test was used to calculate statistical heterogeneity in the meta-analysis. Results There were 240 patients from 5 studies (109 in the SLTO group and 131 FSLO in group). The primary outcome of this study is testicular descent and atrophy. There were no significant differences in testicular descent (RR:1.08[0.96 - 1.23],p<0.20,I 2:0%) and atrophy rate (RR:0.45[0.19 - 1.09],p<0.08,I 2:0%). Secondary outcomes are the duration of operation in both the first and second stages. Statistical analysis reveals a significantly lower first-stage operation time in the FSLO group (MD:9.31[7.08,11.55], p<0.05;I 2:94%). At the same time, lower second-stage operation times are significantly reported in the SLTO group (MD:-4.05[-7.99,-0.12],p<0.05; I 2:60%). Conclusions In terms of testicular descent and testicular atrophy the SLTO technique yields similar results to the FSLO technique. Both techniques have advantages and disadvantages, and we recommend SLTO as the first choice in children with a high IAT of <4 cm. PROSPERO registration CRD42023412407.

J Pediatr Surg 2023; 58:2020-2026. [PMID: 37202294 DOI: 10.1016/j.jpedsurg.2023.04.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 04/02/2023] [Accepted: 04/19/2023] [Indexed: 05/20/2023]
Abstract
BACKGROUND Staged laparoscopic traction orchiopexy (SLTO) is a novel technique for the intra-abdominal testis (IAT) based on elongation of the testicular vessels without separating them. This multicenter study evaluated the medium-term results of this technique. METHODS Data of SLTO performed in three pediatric surgical centers between 2013 and 2020 were analyzed retrospectively. In 2021, physical and Doppler ultrasound examinations were performed to determine the position and viability of testes. Success was defined as an intra-scrotal testicle without atrophy. RESULTS SLTO was performed on 48 cases (55 testes, 7 bilateral). Mean age at first stage was 2.9 (0.8-12.6) years. High intra-abdominal testes were found in 16.4% and in 60% morphological abnormalities were observed. To fix the testes to the abdominal wall monofilament suture was used in 67.3%, braided in 29.1%. Mean time between the two stages was 16.4 weeks; three testes required redo traction. Perioperative complications occurred in 21 patients (38.2%) including insufficient fixation (11), testicular atrophy (4), wound complications (4), adhesion of the spermatic cords (1) and hydrocele (1). In case of insufficient fixation monofilament sutures were used in 90.9%. In 2021 38 patients (43 testes) had physical and 36 patients (41 testes) had ultrasound examinations. Mean follow-up was 2.7 (0.34-7.9) years. Altogether five atrophies were identified, and three testicular ascents (7.0%) occurred. The overall success rate was 82.2%. CONCLUSIONS SLTO may be a feasible alternative to conventional treatments of IATs. Additionally, braided suture seems to be a better option to fix the testicle to the abdominal wall.

Front Pediatr 2022; 10:928069.

Abstract
BACKGROUND AND OBJECTIVE The optimal treatment protocol of intraabdominal testis is still a matter of debate and until now there are a lot of areas of controversy as regards this challenging subtype. The aim of this report is to document current practice patterns among surgeons from different continents through an online Redcap survey supervised the World Federation of the Association of Pediatric Surgeons (WOFAPS). METHODS A 16-question-survey related to the management of intraabdominal testis was created and administered via RedCap. The WOFAPS headquarters sent an email to all members inviting voluntary survey participation. Data were entered using Microsoft EXCEL spreadsheet and analyzed. Descriptive statistics were performed for each survey item. RESULTS There were 436 WOFAPS members who participated in this study with a response rate of 29%, and the vast majority were pediatric surgeons. Only 13% tried to use hormone therapy aiming to induce testicular descent or to improve future fertility. The choices of various surgical techniques were noted. During laparoscopy, if vessels and cord structure were seen entering the ipsilateral internal inguinal ring, most respondents chose to explore the groin. On the other hand, should there was an absent or atrophic testis, the respondents were split on whether to perform a contralateral orchiopexy. CONCLUSION This survey describes the current practices of a sample of pediatric surgeons and urologists in the management of intraabdominal testis. The use of hormonal treatment, timing of fixation and management in case of passing through vas and vessels through DIR were undisputable. However, management of low-lying and peeing testis together with the management of contralateral testis were still debatable.

Abstract
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.

Abstract
BACKGROUND/PURPOSE Pediatric surgical specialists are often confronted with the difficult task of identifying, diagnosing and managing intra-abdominal gonads in children. Ranging from the intra-abdominal cryptorchid testis to normal or pathologic ovaries and gonads in disorders of sexual development, all intra-abdominal gonads in the pediatric population pose different diagnosis and management challenges. Understanding the hormonal and fertility potential of the gonad and knowing its potential cancer risk is essential when deciding how to manage these patients. In addition, the ideal surgical management for each one of these patients is often debated. METHODS Descriptive literature review. RESULTS/CONCLUSION Herein, we reviewed gonadal formation, common etiologies, diagnosis and management of intra-abdominal testes, pathologic ovaries and gonads in disorders of sexual development. Fertility potential and cancer risk for each were also reviewed and how both affect surgical management of the gonad. TYPE OF STUDY/LEVEL OF EVIDENCE Review Article, Level V.

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.

Abstract
Around 1.4-3.8% of boys in the Western world are operated because of cryptorchidism. This means that orchidopexy remains one of the most common surgical procedures performed in boys. As a consequence, several consensus reports, guidelines, and reviews dealing with the management of cryptorchidism have been published recently. Based on our research and 30 years' experience with the management of cryptorchidism, the intention of the present publication is to advise on the surgical management and comment on the expected outcome, especially with focus on the controversies related to guidelines and reviews. Except for late referral and waiting lists, which may be practical problems, there is no reason to postpone orchidopexy for nonsyndromic congenital cryptorchid testes beyond 6 months. There is good evidence that such strategy improves the fertility potential and decreases the risk of testicular cancer. In cases with genuine gonadotropin insufficiency, early surgical correction is not enough and adjuvant LH-RH treatment should be implemented to improve the fertility potential. Cryopreservation may be an option in case of treatment failure of adjuvant LH-RH. A prerequisite for such management includes serum hormone assessment and evaluation of testicular biopsies at orchidopexy. Ascended testes contribute to 20-60% of operative cases and should be treated when diagnosed.

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
The intra-abdominal testis (IAT) has been always an enigma for both diagnosis and treatment. Imaging techniques are known for low sensitivity for localizing the IAT. It has been universally accepted that the gold standard for localizing the IAT is diagnostic laparoscopy. Orchiopexy techniques for IAT are complicated and attended with a higher rate of failure and complication than those for the palpable testis. For the low-lying abdominal testis, a one-stage procedure without interruption of the vessels has a high success rate. The Prentiss maneuver bridges the borders of normal pathway to gain a straighter course to the scrotum. The interruption of the main vascular supply of the testis, depending on collateral circulation, has been used for many years but with questionable effects on the microscopic delicate structure of the testis. Microvascular autotransplantation was intended to avoid this effect, but it is technically demanding and requires special expertise. The principle of traction has been used in the past but was abandoned due to high rate of atrophy. Recently, traction has been revisited with a new approach with very encouraging results. The key to success in any technique for orchiopexy is the complete absence of tension.

Abstract
PURPOSE There are no formal guidelines for the management of boys with nonpalpable testis. In this article, we report our experience in treating all nonpalpable intraabdominal testis (NPIT) with standard inguinal orchidopexy without dividing the spermatic vessels stating that the Fowler-Stephens technique is no longer indicated for the treatment of the intraabdominal testis. METHODS Between June 2003 and April 2008, we treated 23 boys with NPIT confirmed by ultrasound or laparoscopy. All cases were treated through an inguinal orchidopexy without division of the spermatic vessels by fixing the testis to the scrotum by 2 absorbable stitches even if there was an upward retraction of the scrotal skin. Location and size of testis were reported at 1 week, 1 month, 3 months, and 6 months through physical examination. RESULTS Average age at presentation was 24 months. Ten patients (43%) had the NPIT on the right side, 8 (35%) on the left side, and 5 (22%) were bilateral. We had no intraoperative complications. All patients were discharged on the same day. In all cases, the testis was normal in size and found in the scrotum after 6 months of follow-up. CONCLUSION On the basis of our experience, we believe that the Fowler-Stephens procedure is not indicated anymore in the management of NPIT. Orchidopexy without division of the spermatic vessels should be the treatment of choice even for the cases of very high intraabdominal testis because it does not affect normal testicular vascularization and is minimally invasive.

Abstract
BACKGROUND Laparoscopy is used for the diagnosis and treatment of impalpable testes. We reviewed practice and outcomes in our unit over the last 10 years. METHODS Retrospective case-note review of patients undergoing laparoscopy with or without orchidopexy for impalpable testes. RESULTS Eighty-three patients underwent laparoscopy. Twelve patients had bilateral impalpable testes; 25.3% of testes were identified intra-abdominally, 21% in the internal ring, and 29.5% of cases had vas and vessels entering the deep ring. A 76.5% success rate was achieved following diagnostic laparoscopy and standard open orchidopexy for testes in the region of the internal ring, compared to a 40.0% success rate following one-stage laparoscopic orchidopexy for 'low' intra-abdominal testes. CONCLUSION Laparoscopy is useful in managing patients with an impalpable testis from both a diagnostic and therapeutic standpoint. The success rate following laparoscopic orchidopexy in our non-paediatric specialist centre is lower than in most reports from paediatric specialist centres. This suggests the importance of centralization of such complicated, less frequently performed surgical procedures to a specialist centre.

Abstract
Cryptorchidism is one of the most common genitourinary disorders in young boys. Although the management of boys with palpable testis is standardized, there are no formal guidelines for the management of boys with nonpalpable testis. In this Review we look at the current trends in the diagnosis and treatment of this disorder, as well as the indications for therapy and surgical procedures. On the basis of current evidence, we find that there is no optimum orchidopexy technique for the treatment of intra-abdominal testis, although it is preferable to adopt techniques that preserve the spermatic vessels. We also briefly examine the follow-up of patients with this disorder and its common complications. As yet, there are no data that assess the potential of laparoscopic orchidopexy being a risk factor for impaired fertility later in life.

Abstract
The undescended testis is one of the most common congenital abnormalities of the genitourinary system. Outcomes of orchiopexy include (1) having a viable, palpable testis in the scrotum, (2) fertility, as measured by paternity rates or semen analysis in adulthood and (3) risk of testicular cancer. Multiple operative techniques have been described and are associated with various success rates. In the past decade, success of orchiopexy for inguinal testes has been >95%. For abdominal testes, success for orchiopexy has been >85-90% in most series with single stage orchiopexy or two stage Fowler-Stephens orchiopexy, both with open surgical or laparoscopic technique. However, having a palpable testis in the scrotum does not assure fertility, as there are iatrogenic factors that may adversely affect the outcome. In adult men with a history of unilateral orchiopexy, fertility is nearly normal, but is significantly reduced following bilateral orchiopexy. The risk of testicular carcinoma is increased by a factor of 3.7 to 7.5 times. Tumor type is most commonly seminoma if the testis is undescended, whereas tumors that occur following orchiopexy are much more likely to be nonseminomatous.

Abstract
PURPOSE Previous reports of orchiopexies have shown an 85.9% success rate for staged Fowler-Stephens orchiopexy (FSO). We review our experience with nonpalpable testes (NPTs). MATERIALS AND METHODS A total of 119 patients with 128 NPTs were treated at our institution between 1994 and 2001. Atrophic testes or "nubbins" were removed. Once an intra-abdominal testis was identified the peritoneum was opened and firm traction was placed on the gonad. If feasible, primary orchiopexy was completed. Otherwise, staged Fowler-Stephens orchiopexy was performed. RESULTS Primary orchiopexy was performed in 28 testes in 27 patients without division of the spermatic vessels. An atrophic nubbin was removed in 45 patients. All children with bilateral NPTs had at least 1 viable intra-abdominal testis found at surgery. Staged FSO was performed in 55 testes in 47 children. The second stage was performed at a median of 3.5 months after initial ligation of the spermatic vessels. Median followup was 1 year and mean followup was 9 months. Five patients were lost to followup. Successful surgery was defined as a dependent scrotal location and testis size equivalent to the contralateral mate. The overall success rate for the primary orchiopexy group was 100%. In the staged FSO group 1 patient had an atrophic testis at 1-year followup, yielding an overall success rate of 98%. CONCLUSIONS A high degree of success can be obtained for children with intra-abdominal testes. Mobility of the testis on exploration is a good indicator that the testis can be managed with primary orchiopexy without division of the vessels. If primary orchiopexy cannot be performed, excellent results are achieved with a staged FSO.

Abstract
PURPOSE OF REVIEW Laparoscopic surgery in pediatric urology is beginning to accelerate in its application and this has been reflected in increasing series of progressively more complex procedures. To review these, and assess the character of this evolution, articles dealing with diagnostic and operative laparoscopic surgery from mid 2002 to late 2003 have been reviewed. RECENT FINDINGS Several important trends can be seen, including the emergence of increasing numbers of multi-center studies, comparative assessments between properly matched open procedures, as well as comparisons between various laparoscopic techniques. The role of diagnostic laparoscopy in cryptorchidism seems well established, although attempts at being more selective in its application have been published. Operative procedures are being performed to include not only simple removal of tissues, but also reconstructive procedures such as pyeloplasty in more than anecdotal numbers. A strong emphasis has been placed on retroperitoneal access, which is inherently more attractive, but the challenges of this technique are evident. Ultimately it should become more efficient with experience. SUMMARY There has been a steady and progressively more widespread application of laparoscopic techniques in pediatric urology, which has been somewhat slow to develop compared with adult laparoscopy. It seems likely that this progression will continue to accelerate.

Abstract
PURPOSE OF REVIEW Laparoscopic procedures in paediatric urology are gaining popularity, with an increasing number of centres performing advanced surgery. Indications have expanded from diagnostic to ablative surgery and more recently to reconstructive procedures. The current status of the indications and results of different laparoscopic procedures dealing with paediatric urology are reviewed. RECENT FINDINGS Laparoscopic orchiopexy for intra-abdominal testis gives better results than classic open surgery procedures. Palomo modified varicocelectomy with lymphatic preservation is the optimal surgical procedure to treat varicocele in adolescents. The retroperitoneal approach to renal surgery is gaining popularity. Total and partial nephrectomies are feasible in comparable operative times with open surgery and shortened hospital stays. Dismembered pyeloplasty remains a challenging procedure limited to few centres, with excellent midterm results. Laparoscopic adrenal surgery has been extended to neuroblastoma in selected cases. Laparoscopic transvesical ureteric re-implant is now feasible, and opens a new era in bladder surgery. Finally, results of the initial experience with robot-assisted pyeloplasty are now available in children, and showed similar results with regard to the postoperative course, but shorter operative times with experience. SUMMARY The value of laparoscopic orchiopexy for intra-abdominal testis and ablative surgery such as total and partial nephrectomy and adrenalectomy has been confirmed. Robot-assisted laparoscopic surgery will probably popularize challenging procedures such as pyeloplasty and ureterovesical re-implant, which are still limited to a few centres. Despite an increase in the number of publications dealing with the results of laparoscopic procedures, efforts are still needed to validate the benefits of such procedures over open surgery.
