Abstract
BACKGROUND Staged laparoscopic management of intra-abdominal testes using pedicular section is recognized as gold standard technique, successful in 85 % of cases for scrotal testicular position with less than 10 % testicular atrophy. Recently, Shehata proposed a new technique without pedicular division for these testes, using spermatic vessels traction, but did not provide a comparative study of the two techniques. OBJECTIVE To evaluate the laparoscopic spermatic pedicular traction (Shehata technique, ST) for the treatment of intra-abdominal testis, as an alternative to gold standard pedicular section (2-stage Fowler-Stephens, FS). STUDY DESIGN Intra-abdominal testes of 129 patients in two tertiary pediatric urology centers were managed laparoscopically (2011-2019) either by 2-stage FS orchidopexy or ST according to the surgeon preference. Testicular position and size were statistically compared. RESULTS A total of 147 testes were pulled down by 80 ST and 67 FS, including 18 bilateral cases. Median (IQR) age at surgery was 24.2 (15.6-46.4) months (ST) and 18.3 (13.1-38.2) months (FS) (p = 0.094). Scrotal pulling-down of the testis was performed after a median (IQR) period of 2.3 (1.6-3.4) months (ST) and 6.1 (4.7-8.3) months (FS), respectively (p < 0.005). Although ST had collapsed in 17 cases (21.3 %), only one (1.3 %) redo procedure was required. After a median (IQR) follow-up of 22 (12-40) and 19 (8.75-37) months (p = 0.59), the testis was in the scrotum in 85 % and 81 % of ST and FS cases, respectively (p = 0.51). Testicular atrophy occurred in 10 % of ST and 13.4 % of FS (p = 0.61). Multivariate analysis using the propensity score analysis did not identify any difference between the two techniques. DISCUSSION Our results seem to confirm that FS and ST achieve the same results regarding final testicular position and testicular atrophy rate, with a long-term follow-up. Our study supports pediatric surgeons to favor laparoscopic spermatic pedicular traction (ST) which preserves the testicular vascularization and may ensure better spermatogenesis after puberty. More details on the size and position of the testicle at the beginning of the first laparoscopy seem however essential to assess more accurately the outcomes of each surgical technique. Our outcomes will also be re-evaluated when our patients have reached puberty, from an exocrine and endocrine points of view. CONCLUSIONS This study showed similar results after laparoscopic traction or section of spermatic vessels for intra-abdominal testis in a long-term follow-up, providing more evidence for the use of ST as a valuable alternative to FS.

Abstract
Introduction Undescended testes are recognised in 1% to 2% of boys during the first year of life, and about 20% of them are impalpable. Ultrasonography (US) may establish the localisation of the testis but the final diagnosis is usually determined laparoscopically. Aim To evaluate long-term results of laparoscopic treatment of boys with impalpable testes and sensitivity of preoperative ultrasound. Material and methods Between 2011 and 2015, we operated on 545 boys with undescended testes. Sixty-two of them with 65 impalpable testes were treated laparoscopically – the study group. Mean age was 3.5 years. The study group was divided into 5 groups according to type of treatment. The volume and position of the operated gonad were assessed manually and by ultrasound. Results In group 1 testicular agenesis was observed in 19 patients. In group 2 revision of the inguinal canal revealed testicular agenesis in 7 and atrophy in 4 patients. In group 3 conversion to classic orchiopexy was performed in 10 patients. In group 4 one-stage orchiopexy was performed in 9 patients on 12 testes. In group 5 a two-stage F-S procedure was performed in 13 patients. Ten testes in group 4 had a volume in the normal range (84%) and also 10 testes in group 5 (77%). Conclusions Laparoscopy in impalpable testes is the procedure of choice and allows definitive management, even when conversion to open procedure is necessary. Sensitivity of preoperative ultrasound is generally about 60% for true intra-abdominal testes, so diagnostic laparoscopy is necessary.

Abstract
OBJECTIVE To compare single-stage laparoscopic orchiopexy (SSLO) and staged Fowler-Stephens (SFS) procedures in the management of intra-abdominal undescended testes, and to analyze postoperative atrophy and malpositioning as end points. MATERIALS AND METHODS A retrospective chart review identified laparoscopic orchiopexy patients with intra-abdominal testes between November 2006 and November 2014. Of 167 patients who had laparoscopic orchiopexy, 73 (85 testes) were identified as having laparoscopic orchiopexy. Baseline characteristics, as well as testicular scrotal position and size at follow-up, were recorded. Regression analysis was performed to compare outcomes between patients who underwent SFS and SSLO. RESULTS Of the 85 laparoscopic orchiopexies, 35 underwent SFS and 50 had SSLO. Patient demographics were comparable in both groups. The median age at surgery was 12 months (5-151 months), and the average follow-up was 17.3 months. On follow-up, there were 0 recorded cases of SFS patients with abnormally positioned testes postoperatively, whereas there were 10 (20.0%) SSLO patients who had abnormally positioned testes (odds ratio: 0.05, 95% confidence interval: 0.01-0.44). Differences in atrophy rates were not significant. CONCLUSION These results suggest that there may be no difference between the 2 approaches in terms of postoperative atrophy. However, the SFS appears to be more successful in securing a favorable scrotal position. Atrophy does not seem to be associated with other patient factors. Prospective, randomized studies are indicated to further explore outcome differences between the 2 approaches.

Abstract
The use of laparoscopic surgery has grown dramatically in recent years in most all types of surgery. Historically, the early use of laparoscopic surgery was for pelvic and groin problems. In this article we review the current technique, indications, benefits and complications of laparoscopy in diagnosis and management of various groin problems in children including undescended testes (non-palpable and palpable) and inguinal hernia.

Abstract
OBJECTIVES To evaluate the significance of a scrotum pulling maneuver during diagnostic laparoscopy for impalpable testis in order to determine whether an initial scrotal or inguinal incision should be carried out. METHODS A total of 75 patients undergoing diagnostic laparoscopy were included in the present study. If the vas deferens and spermatic vessels were noted to enter the internal inguinal ring, the affected scrotum was pulled downwards and the movements of the cord structures were observed. If inferior movement of the cord structures at the internal inguinal ring were noted, a scrotal approach was preferred. In the absence of cord structure movement, an inguinal approach was carried out first. RESULTS In 59 (76.6%) out of 77 impalpable testes, the spermatic vessels and vas deferens were noted to enter the internal inguinal ring. In 41 of the 59 cases (69.5%), the cord structures were observed to move inferiorly when the scrotum was pulled downwards. In these cases, a scrotal incision was carried out first. In 97% (40/41), a nubbin testis was found and was then excised. In 23% (18/59), the cord structures did not move on pulling the scrotum, and an inguinal approach was initially carried out on these cases. A viable testis was found on the inguinal canal in four cases, and a nubbin testis was excised in 14 cases. CONCLUSIONS In patients with impalpable testis undergoing diagnostic laparoscopy, identification of spermatic cord movement along the internal inguinal ring while pulling the scrotum downwards determines the most appropriate surgical approach. This maneuver might also prevent inappropriately placed skin incisions.

Abstract
INTRODUCTION To demonstrate that laparoscopic intervention should be considered as the initial surgical approach in the management of the non-palpable testis (NPT). METHODS From 2007 to 2011, 100 testicular units underwent same surgeon laparoscopic management for NPT. Diagnostic laparoscopy was performed in all NPT and intra-abdominal testes (IAT) were managed by laparoscopic orchiopexy if low, laparoscopic Fowler-Stephens technique if high, and laparoscopic orchiectomy if atrophic. Percutaneous access to the abdomen was performed in most cases and laparoscopic management was performed with three 5 mm ports. We compared patient's age, race, pre/post-operative exam, pre-operative work up, and IAT location upon laparoscopic intervention with surgical outcome. Fisher's exact test for two independent proportions was used for statistical analysis and reported our results. RESULTS One hundred testicular units underwent diagnostic laparoscopy for NPT. All patients were from Puerto Rican descent. 55.0% were found to be intra-abdominal and were subdivided into groups according to surgical intervention. Mean post-operative follow-up was 24 months. Patients 24 months of age or younger undergoing diagnostic laparoscopy for NPT had a statistically significant probability of resulting in successful laparoscopic orchiopexy as opposed to laparoscopic orchiectomy due to an atrophied IAT (n = 55 testicular units, p < 0.05). No laparoscopic related complications were reported. CONCLUSION Our findings support the use of an initial laparoscopic approach in the NPT as the majority of these patients will have IAT, avoiding unnecessary inguinal and scrotal explorations. We also recommend that patients with IAT should undergo laparoscopic orchiopexy prior to 2 years of age to increase probability of successful management. Further studies focusing in patients with NPT are needed in the future to confirm our findings.

Abstract
BACKGROUND Undescended testis (UDT) or cryptorchidism is the most common genital anomaly seen in boys and can be treated surgically by orchidopexy. The age at which orchidopexy should be performed is controversial for both congenital and acquired UDT. METHODS A decision analysis is performed in which all available knowledge is combined to assess the outcomes of orchidopexy at different ages. RESULTS Without surgery, unilateral congenital UDT and bilateral congenital UDT are associated with average losses in quality-adjusted life-years (QALYs) of 1.53 QALYs (3% discounting 0.66 QALYs) and 5.23 QALYs (1.91 QALYs), respectively. Surgery reduces this QALY loss to on average 0.84 QALYs (0.21 QALYs) for unilateral UDT and 1.66 QALYs (0.40 QALYs) for bilateral UDT. Surgery at detection will lead to the lowest QALY loss of 0.91 (0.34) and 1.73 (0.60) QALYs, respectively, for unilateral and bilateral acquired UDT compared with surgery during puberty and no surgery. No sensitivity analysis is able to change the preferences for these strategies. CONCLUSIONS Based on our decision analytic model using societal valuations of health outcomes, surgery for unilateral UDT (both congenital and acquired) yielded the lowest loss in QALYs. Given the modest differences in outcomes, there is room for patient (or parent) preference with respect to the performance and timing of surgery in case of unilateral UDT. For bilateral UDT (both congenital and acquired), orchidopexy at any age provides considerable benefit, in particular through improved fertility. As there is no strong effect of timing, the age at which orchidopexy is performed should be discussed with the parents and the patient. More clinical evidence on issues related to timing may in the future modify these results and hence this advice.

Abstract
Background. Abdominoscrotal sonogram is often used in boys with a nonpalpable testis to determine the presence of the testis. We describe our experience with the use of ultrasonography in boys with a nonpalpable testis. Methods. We retrospectively reviewed the medical records of boys aged less than 14 years, who underwent preoperative ultrasonography for an impalpable undescended testis (IUDT) between 2006 and 2010 in our institution. The results of sonography and laparoscopy were compared. Results. A total of 26 impalpable testes in 22 patients, including 4 with bilateral impalpable testes, were preoperatively assessed by ultrasonography for their localization. Sonography localized only 6 of the 26 (23%) testes, which were laparoscopically explored and followed by orchiopexy. Conclusion. Ultrasound is not reliable in the preoperative assessment of patients with impalpable testes.

Abstract
Background. Undescended testis is one of the most common urological problems in children, affecting about 1% of boys at age of 1 year. Of these, about 20% have a nonpalpable testis with a very high probability that the testis is absent. This may have a significant impact on the possibility of malignancy in these testes, as well as on the later fertility of these subjects. Methods. We retrospectively analyzed the demographic and clinical findings, as well as immediate and 6-month outcomes, in 91 patients diagnosed with impalpable undescended testes between January 2006 and December 2010. Results. Of the 91 patients, 9 had bilateral and 82 had unilateral impalpable testes. All 100 testes were managed laparoscopically. The largest group of intra-abdominal testes in this series, 42 testes, was entering the internal ring; in these, laparoscopic exploration and standard open orchiopexy resulted in a 66% success rate. The total success rate was 63.3%. Conclusion. Laparoscopy is extremely useful in both the diagnosis and treatment of impalpable testes. Objectively measured mobility of the testis towards the contralateral internal inguinal ring is an excellent intraoperative indicator for type of orchiopexy. Standardization of management may increase the success rate of orchiopexy.

Abstract
PURPOSE Controversy exists regarding the best approach to impalpable testes. We determined the usefulness of diagnostic laparoscopy for the management of impalpable testes. MATERIALS AND METHODS Between 2000 and 2008, 86 patients with a mean age of 34 months underwent diagnostic laparoscopy. An inguinal canal exploration was performed in all cases, except in patients in whom the internal spermatic vessels terminated intraperitoneally with a blind end. RESULTS The undescended testis was right-sided in 24 patients (27.9%), left-sided in 47 patients (54.7%), and bilateral in 15 patients (17.4%). Three patients (3.5%) had bilateral impalpable testes. The vas and vessels traversed the internal ring in 51 of 89 impalpable testes (57.3%); 20 (22.5%) were localized intraperitoneally, and 18 (20.2%) were diagnosed as vanishing testes. Open orchiopexies were performed on 24 testes (27.0%) and orchiectomies were performed on 43 nubbin testes (48.3%). After a mean follow-up period of 30 months, 12 of the 14 testes (85.7%) were viable following open conventional orchiopexy, compared with 6 of the 10 testes (60%) following a 1-stage Fowler-Stephens orchiopexy. CONCLUSIONS Diagnostic laparoscopy is a very helpful and minimally invasive technique in the diagnosis of impalpable testes, especially when preoperative ultrasonography is not sufficiently informative.

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.

Abstract
BACKGROUND The late descent of a testicle into the scrotum may impair its development. Reduced fertility is the main risk of primary cryptorchidism even after timely treatment, as histopathological changes (Leydig cell hypoplasia) already become apparent in the first few months of life. There is evidence, however, that treatment is often delayed. Hormonal and surgical treatments complement each other and should be provided before the child's first birthday. METHODS Selective literature search in PubMed (January 2008) based on the following keywords: "cryptorchidism", "maldescensus testis", "etiology", "therapy", "semen quality", "testicular cancer". Particular attention was paid to the current S2 guidelines on cryptorchidism. RESULTS/DISCUSSION Hormone therapy is the best initial treatment in most cases, with a few exceptions. If this is unsuccessful, surgery should be performed without delay. The success of treatment depends on the initial position of the testicle. Treatment does not lessen the risk of malignancy. Parents must be informed about this risk. The undescended testicle is the most common genital malformation in boys. When diagnosed, it should be treated hormonally and/or surgically before the child's first birthday to minimize the risk of impaired fertility. Successful treatment before age 13 appears not to lessen the risk of testicular cancer, but it does facilitate early detection by enabling physical examination of the testicle.

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
Context: Minimal access surgery (MAS) in children are common place and performed worldwide with gratifying results as the learning curve of the surgeon attains plateau. We share our experience of this technically evolving modality of surgery, performed at our setup over a period of 5 years. We also review and individually compare the data for commonly performed procedures with other available series. Author also briefly discuss potential advantages of MAS in certain debatable conditions performed quickly and with cosmesis as open procedure. Materials and methods: We performed 677 MAS in children aged between 7 days and 12 years. Five hundred and sixty-eight of these were Laparoscopic procedures and 109 were Video assisted thoracoscopic surgeries (VATS). In all laparoscopic procedures, the primary port placement was by the Hasson's open technique. We have used 5, 3 and 2 mm instruments. Our study include 259 inguinal hernia, 161 Appendectomies, 95 VATS for empyema, 51 orchiopexies, 49 diagnostic laparoscopy, 29 cholecystectomies, 22 adhesionlysis and other uncommonly performed procedures. Results: The ultimate outcome of all the performed procedures showed gratifying trend, the data of which are discussed in detail in the article. Conclusion: As we gained experience the operating time showed a decreasing trend, the complication rates and conversion rate also reduced. The advantages we came across were better postoperative appearances, less pain and early return to unrestricted activities.

Abstract
DNA flow cytometry is a sensitive and rapid technique to evaluate the germ cell maturation of testis. The haploid cell population of testis specifically denotes testicular maturation. High ligation of spermatic vessels (HLSV) and low ligation of spermatic vessels (LLSV) have been described in the surgical treatment of high undescended testis. Estimation of germ cell population of testis after these maneuvers has not been performed so far by DNA flow cytometry; hence this study was designed. Thirty male rats, aged 30 days, were randomized into three groups. Group I underwent sham surgery; group II underwent unilateral HLSV-ligation and division of main spermatic vessels, similar to the Fowler-Stephens technique; and group III underwent unilateral LLSV-ligation and division of main spermatic vessels close to the testis, similar to the Koff and Sethi technique. Thirty days later, the ipsilateral testes were harvested, and haploid, diploid, and tetraploid cells were counted by DNA flow cytometry. The mean (+/-SD) percentage of the haploid cell population was 68.7+/-4.8, 49.3+/-6.5, and 50.8+/-6.4 in groups I, II, and III, respectively. There was a significant (p<0.05) decrease in haploid cell population between groups I and II and between groups I and III. However, there was no significant difference between groups II and III. In conclusion, prepubertal HLSV as well as LLSV decreases the haploid cell population of ipsilateral testis in rats. LLSV has no advantage over HLSV.

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 Increased use of video laparoscopy in the diagnosis and treatment of the impalpable testis has encouraged use of the 2-stage Fowler-Stephens orchiopexy. To date, however, few limited studies exist to indicate whether clipping and division of the spermatic vessels alone may cause histological abnormalities in the intra-abdominal testis. MATERIALS AND METHODS We evaluated histology and volume of 44 intra-abdominal testes in 35 patients between 4 months and 14 years old at stages 1 and 2 of the Fowler-Stephens procedure. RESULTS There was a significant reduction in the number of spermatogonia and seminiferous tubules 6 months after ligation and division of the spermatic vessels. No differences were found in the number of Sertoli cells or testicular volume before and after clipping and division of the spermatic vessels. CONCLUSIONS Ligation of the spermatic vessels during stage 1 orchiopexy for intra-abdominal testicles is associated with a significant reduction of spermatogonia. However, no significant changes were observed in the volumetric characteristics of the testicles. Further studies are necessary to evaluate the repercussions of these changes in future fertility.

Abstract
PURPOSE We evaluated laparoscopic diagnostic findings in 108 impalpable testes, and analyzed the success rate and long-term outcome of either direct laparoscopic orchiopexy or the 2-stage Fowler-Stephens procedure. MATERIALS AND METHODS A total of 84 children with 108 impalpable testes and a mean age of 1.9 years underwent laparoscopy between 1992 and September 2000. Long-term outcome with regard to viability and location of the testes was evaluated. RESULTS Of the 108 testes 72 were located intra-abdominally, of which 28 were managed by direct laparoscopic orchiopexy, 29 were managed by a 2-stage laparoscopic Fowler-Stephens procedure and 15 were vanishing. The remaining 36 testes were inguinally located during exploration and orchiopexy, except for 5 vanishing testes. In all cases the operation proceeded as planned. After a mean followup of 6.2 years all laparoscopically managed testicles were in a normal scrotal position with normal perfusion as revealed by color flow Doppler sonography. Two testicles became atrophic after a 2-stage Fowler-Stephens procedure. Morbidity was low in all children. CONCLUSIONS The laparoscopic approach allows not only diagnosis, but also adequate therapy regardless of whether direct orchiopexy or a 2-stage procedure is performed. Our long-term results clearly demonstrate that even in the patients undergoing the 2-stage procedure the laparoscopic approach is safe and efficient, and leads to excellent results concerning viability of the affected testicles. Progress and experience gained during recent years are encouraging in continuing laparoscopic procedures in children.

Abstract
Since the introduction of minimal access surgery to general surgeons in the 1980s, pediatric surgeons have been employing this innovative technology to perform surgery on children. Video technology and miniaturized instruments have brought the laboratory to the operating room; in many cases several small incisions are the only access necessary to perform complicated procedures that would otherwise require a large wound. Additional benefits of minimal access surgery may include reduced postoperative analgesic requirements, shortened length of stay, and faster resumption of normal activities. Increased operative costs offset some of these gains. The pediatric surgical community has embraced minimal access techniques for some operations; others remain controversial.

Abstract
The impalpable testicles account for approximately 10 to 20% of the total of the not descended testicles. The importance of laparoscopy is increasingly significant, because apart from its diagnostic role recently a therapeutic interest was added. Thirty-five nonpalpable testicles took advantage of laparoscopic exploration at the pediatric's emergency surgery ward at the children's hospital of Rabat within the last 2 years. In 9 cases, total testicular agenesis was found. In 6 cases the testicles were situated very high in the abdomen, so that a first time laparoscopy was performed where the testicles were lowered. In 10 cases, one laparoscopic intervention for lowering the testicles was sufficient. In 10 cases, laparoscopic surgery showed that the vas deferens and the spermatic vessels reunified in the inguinal; so that, Inguinal exploration was necessary. The time of hospitalisation was 24 h with no complications noticed. We present this work to sensitise the surgeons on the new therapeutic approach to optimise the taking care of cryptorchid boys.

Abstract
BACKGROUND AND PURPOSE The investigation of a child with a nonpalpable testis is probably the most frequent indication for laparoscopy in pediatric patients. The objective of this study was to evaluate the results and advantages of laparoscopy-assisted orchidopexy performed without dividing the spermatic vessels. PATIENTS AND METHODS During a 3-year period, 85 boys with nonpalpable testes (NPT) (91 testes overall) underwent laparoscopic diagnostic exploration. Twenty-five patients (27.4%) showed an intra-abdominal testis (IAT): 24 underwent a laparoscopy-assisted orchidopexy (LAO) without sectioning of the spermatic vessels, and one, whose inner spermatic vessels were not adequately long for LAO without tension, underwent a two-step Fowler-Stephens (FS) procedure. The technique consists of dissection and mobilization of the inner spermatic vessels and the vas deferens from the posterior peritoneum, sectioning of the gubernaculum attachments, and bringing down of the testis into the scrotum through the internal inguinal ring, if open, or through a neo-inguinal ring created medial to the epigastric vessels. RESULTS Surgery lasted between 40 and 80 minutes (median 60 minutes). All the testes were brought down into the scrotum. There was only 1 (4%) intraoperative complication, which occurred in the second patient operated on with this procedure. He experienced an iatrogenic rupture of the spermatic vessels secondary to excessive traction. CONCLUSION Laparoscopic orchidopexy is the logical extension of diagnostic laparoscopy for the evaluation of NPT. Concerning the technique, we believe that LAO with intact spermatic vessels could be considered the treatment of choice in the patient with IAT, as it does not affect normal testicular vascularization. Alternatively, in the case of very high IAT (more than 3 cm from IIR), an FS procedure may be considered.

Abstract
In this study, we investigated the effects of one- and two-staged orchiopexy on testicular volume and serum testosterone levels in cases with high, abdominally localized, bilateral nonpalpable testes. Between March 1996 and April 2001, orchiopexy was performed on 46 testes in 23 patients with bilateral nonpalpable testes. In 15 of the 23 patients, a two-stage Fowler-Stephens orchiopexy was performed, and in 8 of the 23 patients, a one-stage laparoscopic orchiopexy was performed. For one patient who lacked both testes, bilateral prosthetic testes were inserted. The patients' ages were between 20 and 23 years (average, 21 years). In the first stage of the two-stage orchiopexy, the spermatic artery was ligated laparoscopically. Six months later, open surgery orchiopexy was performed. Patients were followed for 2 to 16 months (average, 10 months) and were evaluated for testicular atrophy, serum testosterone levels, and complications. In all the patients, the preoperative secondary sexual characteristics and serum testosterone levels were normal. Among the postoperative controls, evaluated at months 3 and 6, one patient's testes were found at the pubic area. Testicular atrophy was not observed in any of the patients, and the serum testosterone levels were in the normal range. In the two-stage orchiopexy group, 5 (33%) of the 15 patients had an average 30% volume decrease, and in the one-stage group, 2 (25%) of the 8 patients had an average 40% volume decrease. In this study, it was shown that either two-stage Fowler-Stephens orchiopexy or laparoscopic orchiopexy can be successfully performed in patients with bilateral abdominal testes, and that the testes can be fixed to their palpable original positions without interfering with the secretion of testosterone. Although the results are similar, our experience suggests that single-stage laparoscopic orchiopexy is the preferable method.

Abstract
Mention of all of the procedures in urology that have been attempted, or are being done, laparoscopically is beyond the scope of this article. The laparoscopic procedures outlined in this article are gaining increasing support as surgeons attempt to redefine gold standard minimally invasive therapies in the new millennium. Additional procedures, such as laparoscopic retroperitoneal lymph node dissections for low-stage, nonseminomatous germ cell testicular cancers and laparoscopic renal cryoablation of small renal cancers, are soon to be added to this list. As laparoscopic instrumentation and equipment continue to improve, it will become possible to explore even more procedures laparoscopically. Advances in imaging techniques, lasers, miniaturized robotics, and other areas may further define what is meant by the term minimal access surgery in the decades to follow.

Abstract
Not more than 10 years ago, laparoscopy was introduced to the armamentarium of urology. The start was slow, with pelvic lymphadenectomy, nephrectomy and varicocelectomy being about the only indications. However, very soon great enthusiasm developed, and almost every urological operation was performed by means of laparoscopy. For several reasons this exaggerated enthusiasm had to be followed by disappointment. First of all, laparoscopy turned out not to be as easy as many would have liked it to be. Due to a low frequency of operations, many surgeons were never able to overcome their learning curve, and the early literature reflects this problem. Unlike general surgery where cholecystectomy developed into a pacemaker operation, which forced everybody to go ahead with laparoscopy, urology was long searching for good and frequent indications for this new technique. Within the last few years, the pendulum has swung back to the other side. Adrenalectomy was one of the first indications where laparoscopy proved superior to open surgery in every aspect. Several other good indications have followed, some of which, namely cryptorchidism, nephrectomy and pyeloplasty, will be presented in detail to give an example. But the breakthrough that recently occurred is due to the success of laparoscopy in the field of oncologic surgery. Laparoscopic radical nephrectomy has shown its surgical efficiency as well as its oncologic efficacy. However, the main interest is now focused on radical prostatectomy, since this is the most frequently performed operation in urology by now. Recently this operation could be developed to a standardized technique, but only time will tell its true impact. Several indications will change in the future, but laparoscopy is here to stay.

Abstract
The use of minimally invasive surgery (MIS) in children and adolescents is steadily increasing. The aim of the present review was to summarize the status of MIS in pediatric endocrinology. We found that laparoscopic procedures have been proven useful for the diagnosis or treatment of endometriosis and its associated manifestations, undescended testicles, ambiguous genitalia, adnexal torsion and ovarian cyst. Considering the safety and efficacy of these applications, the more rapid recovery of the patients, and the considerably less pain induced, we believe MIS will gradually take precedence over standard procedures in many areas of endocrinology in the young population.

Abstract
PURPOSE Laparoscopy is a well described modality that provides an accurate visual diagnosis upon which further management of intra-abdominal testes may be based. Laparoscopic ligation of spermatic vessels as stage 1 of the procedure is a natural extension of laparoscopy. A staged approach provides adequate viability of the intra-abdominal testis. However, it is uncertain whether the more sensitive germ cells survive this procedure in addition to the Sertoli and interstitial cells of the human testis. Survival of germ cells is a prerequisite of later fertility potential. MATERIALS AND METHODS We studied 17 nonpalpable testes in 10 patients 1 year and 7 months to 13(1/2) years old. Results of testicular biopsies of 13 intra-abdominal testes taken at stages 1 and 2 of surgery were available for histological comparison. RESULTS Median number of spermatogonia per tubular cross section of the biopsies taken at stage 2 was slightly lower (0.03) compared to the median number at stage 1 (0.06) of the operation but this difference was not significant (p = 0.2031). CONCLUSIONS Our study shows that the spermatogonia may survive clipping and division of the spermatic vessels, although the number of spermatogonia per tubular transverse section decreases slightly.
