Laparoscopic Management of Cryptorchidism in Adults

The role of laparoscopy in non-palpable undescended testicle: Analysis and review of the experience from two cities in Sudan

INTRODUCTION

It is estimated that 1%-2% of male infants have undescended testicles. The reliability of ultrasound (US) to identify the non-palpable undescended testicles (NPUDT) is controversial. Laparoscopy remains the gold standard to diagnose and manage NPUDT.

OBJECTIVE

The objective is to highlight the role of laparoscopy in the management of NPUDT in 2 cities from Sudan over the past decade.

MATERIALS AND METHODS

Patients presented to Gadarif Teaching Hospital and Almak Nimir University Hospital with NPUDT were assessed by clinical examination and US. The testis, when found during laparoscopy, was either brought down to the scrotum in a single or two-stage or removed depending on the findings. Data were collected and analysed.

RESULTS

Patients covered the age range between 18 months and 65 years. The average was 12.4. The majority, 94 (67.2%) patients were older than 5 years. The main presenting symptom was either bilateral or unilateral empty scrotum. In 12 (8.4%) patients, the main presenting symptom was primary infertility. US was done in 120 (86.6%) of the patients and failed to see the testis in more than half of them. A single-stage procedure in the form of laparoscopic search assisted with orchidopexy was achieved in 90 (62.9%) patients and orchiectomy in 13 (9.1%) patients, while in 12 (8.4%) patients the testis was not found. Other procedures were applied on the 28 (19.6%) patients who needed staged operation in the form of Fowler Stephen's, in bilateral cases, in 6 (4.2%) patients. Shehata's operation in nine patients (64%) and open orchidopexy for 8 (5.6%) patients. The post-operative complication was encountered in 14 (9.8%) of the patients in this group in the form of bleeding, vassal injury and testicular atrophy.

CONCLUSION

Laparoscopy provides the most accurate interventional option for managing patients with NPUDT. Laparoscopic orchidopexy, whether single stage for low or 2-stages for high intra-abdominal testis, is a proven and effective extension of lap-search with minimal complications.

Management of cryptorchidism in adolescent and adult males

Background

In developing countries, it is not unusual for patients with undescended testes (UDT) to present in adulthood and the late detection of UDT can be problematic. The limited contribution to fertility and increased potential of malignancy seen in UDT have swayed many authors towards recommending orchidectomy, rather than orchidopexy, for the adult patient presenting with cryptorchidism. With conflicting data, and most guidelines aimed at first world countries with pre-pubertal patients as their focus group, a lot of uncertainty exists regarding the management of adults who present with cryptorchidism. This may result in variation in the approach to management of this patient population.

Methods

A retrospective review was conducted of patients with cryptorchidism, aged 12 years or older at the time of surgery. The following data were retrieved: patient’s age, medical and previous surgical history, clinical features of UDT (laterality, position and size), date of surgery, intra-operative findings and procedure performed. Management decisions were compared to the most recent guidelines.

Results

The mean age of the 106 subjects was 25.4 years. An orchidectomy was performed in a total of 30 (24.2%) of the 124 testicular units. The majority of testes, 91 (73.4%), in this group were preserved. Of these, 43 (47.3%) were older than 18 years of age, 33 (36.2%) were reported as having unilateral UDT with a normal contralateral testis and in 9 (9.8%) of these cases, the preserved testes were described as being atrophic. The majority (59.7%) of UDT in the post-pubertal group (> 18 years) were managed by orchidopexy.

Conclusion

Contrary to the recommended treatment for this group of patients, there was a general tendency towards testicular preservation. The decision on surgical management was made by the attending surgical team. This not only demonstrates variation in the management of UDT, but could also be a reflection of the lack of sufficient guidelines as to the management of the post-pubertal patient presenting with UDT. Further studies, following cryptorchidism through adulthood, are needed to refine guidelines for the optimal management of this group of patients.

Small bowel obstruction caused by cryptorchidism in an adult

Small bowel obstruction (SBO) is a common complication after abdominal surgery, and can occur due to many reasons. However, cryptorchidism can cause SBO in patients with no history of abdominal surgery. We report the case of a 67-year-old man with SBO caused by adhesions between an undescended testis and the terminal ileum.

Laparoscopy in the management of impalpable testis (Series of 64 Cases)

BACKGROUND

The undescended testis represents one of the most common disorders of childhood. Laparoscopy has been widely used both in the diagnosis and treatment of non-palpable testis. In this study, we investigated and evaluated the usefulness of laparoscopy in the diagnosis and treatment of no palpable testis.

PATIENTS AND METHODS

From January 2003 to January 2008, we used laparoscopy in the management of 64 patients with 75 impalpable testes. Their ages varied from 1 to 15 years (median age = 4.6 years). The site and the size of the testes were localised by abdominopelvic ultrasonography in all 64 children for accurate diagnosis. One stage laparoscopic orchiopexy was performed in 26 testes, staged Fowler-Stephens orchiopexy was underwent in 17 testes, while laparoscopic orchidectomy was done in 5 testes. Follow-up by clinical examination and colour Doppler ultrasound was performed in every patient who underwent orchiopexy.

RESULTS

There were 11 patients with bilateral non-palpable testes. The overall diagnostic agreement of ultrasound with laparoscopy was seen in only 16 out of 75 testes (21.3%). The results of diagnostic laparoscopy were varied and showed various pathological. Conditions and positioned of the testes, such as 20 low intra-abdominal testes (26.6%), 17 testes were high intra-abdominal (22.7%), and 18 testes (24%) entered the inguinal canal. Associated inguinal hernia was present in 4 patients. After a mean follow-up period of 26 months (6 months - 5 years), all testes were in the bottom of the scrotum except 3 testes were retracted to the neck of the scrotum and atrophy of the testis occurred in 2 patients (2.7%).

CONCLUSION

Laparoscopy has proven to be the only diagnostic modality where the findings provide a clear dependable direction for the definitive management of impalpable testes, so it allows an accurate diagnosis and definitive treatment in the same sitting.

Transitional Urology for Male Adolescents: What Adult Urologists Should Know

In recent years, there has been increasing interest in transitional urology, or how to best prepare patients with major congenital urologic diseases, such as bladder exstrophy and neuropathic bladder, to manage their own health care with adult urologists. However, common pediatric urologic conditions may be encountered by the adult urologist with more regularity. This review focuses on three relatively common conditions which may be identified in childhood, the consequences from which a patient may seek help from an adult urologist: cryptorchidism, varicocele, and Klinefelter syndrome.

Individualized Treatment Guidelines for Postpubertal Cryptorchidism

Cryptorchidism is a well-known congenital anomaly in children. However, its diagnosis is often delayed for reasons including patient unawareness or denial of abnormal findings in the testis. Moreover, it has been difficult to establish an optimal treatment strategy for postpubertal cryptorchidism, given the small number of patients. Unlike cryptorchidism in children, postpubertal cryptorchidism is associated with an increased probability of neoplasms, which has led orchiectomy to be the recommended treatment. However, routine orchiectomy should be avoided in some cases due to quality-of-life issues and the potential risk of perioperative mortality. Based on a literature review, this study proposes individualized treatment guidelines for postpubertal cryptorchidism.

Diagnostic performance of diffusion-weighted MRI in the detection of nonpalpable undescended testes: comparison with conventional MRI and surgical findings

OBJECTIVE

The aim of this feasibility study was to evaluate the role of diffusion-weighted MRI in the evaluation of nonpalpable undescended testes.

MATERIALS AND METHODS

Thirty-six boys with undescended testes underwent preoperative abdominal and pelvic MRI to identify the location of the testes. MRI included free-breathing diffusion-weighted imaging (DWI) with b values of 50, 400, and 800 s/mm(2), a T1-weighted turbo spin-echo sequence, and a T2-weighted fat-suppressed turbo spin-echo sequence. After laparoscopic examinations, two observers independently reviewed the preoperative images. The DW images alone were reviewed first, followed by the conventional MR images alone and the conventional MR and the DW images together. The laparoscopic and MRI findings were compared. Sensitivity, specificity, and accuracy in the identification of nonpalpable undescended testes were calculated for DWI, conventional MRI, and the combination of DWI and conventional MRI.

RESULTS

The combination of DWI and conventional MRI was the most sensitive and most accurate technique. Observer 1 found 31 undescended testes, and observer 2, 30 testes with this technique. Sensitivity was 0.91 and 0.88 for observers 1 and 2, and accuracy was 0.92 and 0.86. With DWI alone, observer 1 located 30 testes, and observer 2, 28 testes (sensitivity, 0.88 and 0.82; accuracy, 0.86 and 0.81). Using conventional MRI alone, both observers located 29 testes (sensitivity, 0.85; accuracy, 0.86 and 0.84). The accuracy of locating testes was superior with the combination of DWI and conventional MRI for both observers (accuracy, 0.92 and 0.86). An intraabdominal atrophic testis managed by laparoscopic orchiectomy was found by neither observer with DWI or with conventional MRI.

CONCLUSION

Use of DWI with a high b value yields information that complements conventional MRI findings, improving identification and location of nonpalpable undescended testes. We recommend the use of conventional MRI in addition to DWI to increase the preoperative sensitivity and accuracy of identifying and locating nonpalpable testes.

RESULTS

There were 11 patients with bilateral non-palpable testes. The overall diagnostic agreement of US with laparoscopy was seen for only 16 of 75 testes (21.3%). The results of diagnostic laparoscopy were varied and showed various pathologic conditions and positions of the testes, such as 20 low intraabdominal testes (26.6%), 17 high intraabdominal testes (22.7%), and 18 testes (24%) that had entered the inguinal canal. Associated inguinal hernia was present in four patients. After a mean follow-up period of 26 months (6 months-5 years) all testes were seen to be located in the bottom of the scrotum, with the exception of three testes that had retracted to the neck of the scrotum and two testes that had atrophied (2.7%).

CONCLUSIONS

Laparoscopy has proven to be the only diagnostic modality where the findings provide a clear, dependable direction for definitive management of impalpable testes. It allows an accurate diagnosis and simultaneous definitive treatment.

Is laparoscospic orchidectomy the treatment of choice in adults with impalpable testis in rural hospitals in the developing world?

This study was undertaken in order to evaluate the feasibility and safety of performing laparoscopic orchidectomy (LO) in men for unilateral impalpable testis in non-teaching rural hospitals in a developing country. We also investigated the possibility of reducing the cost and length of stay in hospital for patients undergoing LO. This is a prospective analysis of patients with impalpable testis undergoing LO in three non-teaching rural hospitals in the Kashmir Valley from January 2001 to March 2007. The cohort represented men requiring LO aged 15 to 62 (mean 36.2) years. The main outcome parameters assessed included mortality, conversion to an open procedure, complications, reduction in the costs and the length of the hospital stay. Forty-eight men with unilateral undescended testis on physical examination were studied. During laparoscopy the testis was identified near the deep ring in 30 patients, intra-abdominally in 16, and two had blind-ending vas and spermatic vessels near the deep ring. In 46 patients orchidectomy was performed. There were no deaths and none of the patients required conversion to an open procedure. Using reusable instruments, 00 degrees polyglactin sutures and self-made extraction bags, about US$ 300/patient was saved. There was no case of malignancy of the testis on histopathology examination. LO is one of the most satisfactory methods for the management of men with impalpable testis, having both a diagnostic and a therapeutic role especially for patients in the underdeveloped countries. These simple methods can reduce the cost and the length of the hospital stay.
