Male infertility after surgery for imperforate anus

Adult urological outcomes for patients with anorectal malformation

Anorectal malformations (ARM) are rare congenital anomalies characterized by a spectrum of defects resulting in the absence of a normal anal opening with or without fistula. Urogenital involvement is common, and the fistulous tract may terminate in the genitourinary system in males or within gynecological structures in females. Surgical reconstruction occurs early in life and survival of these patients to adulthood is the norm. There has, therefore, been increased focus on their long-term outcomes to better anticipate and treat the sequelae that may impact their health and well-being as this population ages. For urologists, urinary health, sexual function, and fertility outcomes are of particular interest among this population. This article aims to provide a review of urological, sexual, and fertility outcomes for individuals born with ARM with a focus on key issues that may occur later in life to ensure adequate counseling, screening, and treatment.

Management of the urological tract in children with anorectal malformations - a contemporary review

Anorectal malformations (ARMs) consist of a broad spectrum of congenital anomalies that are associated with an equally wide variety of urological abnormalities, often with increasing incidence as the severity of the ARM increases. The importance of urologic involvement in the care of ARM patients has been noted for decades and is critical from birth to adulthood. Urology must be involved in the initial evaluation and operative care of the child as well as in monitoring and managing issues such as neurogenic bladder, renal disease, and eventually sexual function and fertility. Care of the ARM patient must be done through a multidisciplinary lens, with the urologist as a key player. This review will serve as an update on the management of the urologic tract in children with ARM.

Urological Impact of Epididymo-orchitis in Patients with Anorectal Malformation: An ARM-Net Consortium Study

INTRODUCTION

 To investigate the current experience of the ARM-Net Consortium in the management of epididymo-orchitis (EO) in patients with anorectal malformations (ARMs), and to identify specific risk factors and the need for urological care involvement.

MATERIALS AND METHODS

 We retrospectively collected data of EO in patients with ARM between 2015 and 2019. Data on urological aspects, ARM type, surgical approach, associated anomalies, diagnosis, and treatment of EO were collected and analyzed.

RESULTS

 Twenty-nine patients were reported by 12 centers. Twenty-six patients with EO (90%) had ARM with a rectourinary fistula. Median age at first EO was 2 years (range: 15 days-27 years). Twenty patients (69%) experienced multiple EO, and 60% of recurrences were ipsilateral. Associated urological anomalies included vesicoureteral reflux (48%), urethral anomalies (41%), neurogenic bladder (41%), and ectopic vas (10%). A positive urine culture during EO was present in 69%. EO was treated with antibiotics (90%), limiting surgical exploration to 14%. Prevention of recurrences included surgery (bulking agents 15%, vasectomy 15%, and orchiectomy 5%) and antibiotic prophylaxis (20%).

CONCLUSION

 Urologists may encounter patients with EO in ARM patients, frequently with positive urine culture. An appropriate urologic work-up for most ARM patients is necessary to identify and treat underlying risk factors. A practical scheme for the work-up is suggested for a close collaboration between pediatric surgeons and urologists.

Sexual function and fertility of adult males with anorectal malformations or Hirschsprung disease

PURPOSE

The long-term impact of anorectal malformations (ARM) and Hirschsprung disease (HD) on sexual function is well recognized but understudied. This study evaluated self-reported sexual and fertility outcomes in adult males with ARM and HD.

METHODS

This was an IRB approved, prospective study of males in the Adult Colorectal Research Registry who completed surveys between October 2019 and March 2022. Electronic surveys were administered after consenting to being contacted for research. Patients completed the International Index of Erectile Function (IIEF) questionnaire and provided information on fertility outcomes.

RESULTS

Sixty-five patients completed outcome questionnaires: 11 (16.9%) had HD and 54 (83.1%) had an ARM. Nineteen patients reported some degree of erectile dysfunction per IIEF criteria, a greater proportion of whom have ARM (p = 0.046). Twenty (30.7%) have reported having children; there were no differences in rates between HD and ARM patients. Most patients had not attempted to conceive, but eight patients, all of whom have ARM, have pursued fertility investigation or treatments.

CONCLUSION

More patients with ARM reported some degree of erectile dysfunction compared to those with HD. Additionally, some have required fertility treatments. Further investigation is warranted to ensure true low rates of sexual and fertility dysfunction in patients with HD.

A Comparison of Sexual Function in Male Patients with Anorectal Malformations Between the Conventional and Laparoscopic Approaches

Aim: To compare the incidence of erectile dysfunction and ejaculatory anomalies in male patients with anorectal malformation (ARM) after treatment with the sacroperineal approach (Group S) or laparoscopically assisted anorectoplasty (LAARP; Group L). Methods: Male patients who underwent repair of high- or intermediate-type ARMs at our center and aged ≥15 years as of November 2020 were enrolled. Patients with intellectual disabilities or chromosomal disorders were excluded. Sacroperineal anorectoplasty has long been routinely performed at our hospital, and LAARP was introduced as a standard procedure in 2000. The medical records of the outpatient clinic were retrospectively reviewed, and questionnaires were sent in November 2020. Data regarding erectile dysfunction, ejaculatory anomalies, and associated anomalies were collected and compared between the two groups. Results: Answers were obtained from 7/22 patients in Group S (32%) and 10/17 patients in Group L (59%). Patient characteristics were similar, but the median age at the time of replying was significantly different (22 [18-29] years in Group S and 19 [15-20] years in Group L, P = .0060). None of the patients had erectile dysfunction, but 3 patients in Group S (43%) and 5 patients in Group L (50%) had ejaculatory failure, with no significant difference between the two groups. Conclusions: The incidence of sexual dysfunction in male patients with ARM might be higher than that in the healthy population. Patients might abscond from their follow-up visits as they age; therefore, providing patients with accurate information on this issue before puberty is essential.

Unilateral vasectomy for intractable epididiymo-orchitis in patients with anorectal malformation

BACKGROUND

Male patients treated for anorectal malformations (ARM) and recto-urethral fistula (RUF) tend to develop recurrent epididymo-orchitis (EO) which occurs approximately in 20% of all them. The optimal management of this condition is unclear because of the extreme its rarity and the unavailability of detailed analysis in literature. To date the majority of this patients benefits from medical treatment and symptoms reduce over time but few data have been published in literature about management of patients with intractable EO.

OBJECTIVE

To describe the efficacy of unilateral vasectomy in patients operated on for anorectal malformations with RUF and affected by intractable EO.

STUDY DESIGN

We present five patients who met the criteria for intractable EO, and followed at our centre four of whom have undergone unilateral vasectomy.

RESULTS

The first episode of EO presented at 42,00 mos ±29.39. Initially, patients were all managed with analgesics and antibiotics. For the failure of therapy, five patients were all offered unilateral vasectomy but only four families accepted procedure. Surgical treatment was performed as a day case without complications. Postoperative follow up was 88,50 mos ±68.36. Prompt and durable resolution of symptoms was observed.

DISCUSSION

The long-term effects of recurrent EO in ARM are often underestimated. Prompt and appropriate intervention should prevent this undesirable sequela. Unfortunately, the optimal management of this complication is unclear, partly because of its extreme rarity. The established management needs to follow the route of correcting underlying anomalies and providing long-term analgesic and antibiotics but this may have undesired side effects. We therefore offered families vasectomy for complete symptom resolution and/or drug withdrawal. Vasectomy, as a form of treatment for, can be justified if it can prevent pain, infection and destruction of the testes. Early vasectomy may save enough functional testis tissue.

CONCLUSION

To date, the only available treatment to achieve definitive resolution of symptoms in intractable unilateral EO is vasectomy. Long-term effects of such procedure on fertility are unknown. The treatment of recurrent EO in cases without site predilection remains a matter of contention.

Testicular function and sexuality in adult patients with anorectal malformation

PURPOSE

To collect data on sexual and fertility issues in adult male patients with history of anorectal malformations (ARM).

MATERIALS AND METHODS

Thirty adult males born with ARM, cared for at the Pediatric Surgery of Treviso and Padua Hospitals, were enrolled and interviewed about sexual habits and relationships. Testicular ultrasound, evaluation of male sex hormones and semen analysis were performed to assess testicular function and compare data with 15 fertile controls. Presence of erectile dysfunction was evaluated with IIEF-5 questionnaire.

RESULTS

Cryptorchidism and recurrent orchiepididymitis were reported in 33% and 40% of patients, respectively. Average testicular volume resulted significantly lower than fertile controls (11.1 vs 14.3 mL, p = 0.002) and 53.5% presented testicular hypotrophy (<10 mL). Erectile dysfunction was reported by a single patient and ejaculatory anomalies by 46.5%. Thirteen patients were azoospermic/cryptozoospermic; 6 of them presented a reduced peripheral sensitivity to androgens (ASI > 139). Coital debut resulted delayed at 18 years old (vs 15 years in the control group). Overall 63.5% reported their condition did not affect their sexual sphere.

CONCLUSIONS

Evaluation of testicular function is recommended in ARM patients to detect and treat possible infertility disorders, to recognize the clinical conditions which could affect the spermatogenesis since childhood, and to guarantee psychological support.

Ectopic Intravesical Ejaculatory Ducts: Case Report of Bulking Agent Injection for Treatment of Recurrent Epididymitis in a Patient With Anorectal Malformation

As far as we know this is the first report on bulking agent injection into intravesical ectopic ejaculatory orifices reported in the English literature. During a follow-up period of 23 months, the child was free of episodes of epididymo-orchitis. Deflux injection in this rare anomaly of intravesical refluxing ducts had prevented irreversible damage to the testes from recurrent EO. Thus, it may be a better option than vasectomy when antibiotic treatment fails.

Long-term bowel function, quality of life and sexual function in patients with anorectal malformations treated during the PSARP era

Anorectal malformations are an important group of congenital anomalies that vary widely in their anatomical characteristics and complexity. Understanding the long-term functional outcomes after modern treatments, and how these compare to the general population, are essential for ensuring that patients receive optimal, evidence-based care. With increasing appreciation of the wider impact of the illness on patients and their families, minimizing social disability from fecal incontinence and enabling normal social integration from the outset are key management concerns. This review summarizes the current knowledge on the functional outcomes by type of malformation, reflecting on the literature, and our institutional experience over a follow-up period of nearly 30 years.

The pathophysiology of delayed ejaculation

Delayed ejaculation (DE) is probably least studied, and least understood of male sexual dysfunctions, with an estimated prevalence of 1–4% of the male population. Pathophysiology of DE is multifactorial and including psychosexual-behavioral and cultural factors, disruption of ejaculatory apparatus, central and peripheral neurotransmitters, hormonal or neurochemical ejaculatory control and psychosocial factors. Although knowledge of the physiology of the DE has increased in the last two decade, our understanding of the different pathophysiological process of the causes of DE remains limited. To provide a systematic update on the pathophysiology of DE. A systematic review of Medline and PubMed for relevant publications on ejaculatory dysfunction (EjD), DE, retarded ejaculation, inhibited ejaculation, and climax was performed. The search was limited to the articles published between the January 1960 and December 2015 in English. Of 178 articles, 105 were selected for this review. Only those publications relevant to the pathophysiology, epidemiology and prevalence of DE were included. The pathophysiology of DE involves cerebral sensory areas, motor centers, and several spinal nuclei that are tightly interconnected. The biogenic, psychogenic and other factors strongly affect the pathophysiology of DE. Despite the many publications on this disorder, there still is a paucity of publications dedicated to the subject.

Sexual Function, Fertility and Quality of Life after Modern Treatment of Anorectal Malformations

PURPOSE

Sexual dysfunction and impaired quality of life due to fecal incontinence are common after classic operations for anorectal malformations. We hypothesized that modern repairs may result in improved outcomes.

MATERIALS AND METHODS

Following ethical approval for this single institution cross-sectional study, all patients 16 years or older treated for rectourethral, vestibular or perineal fistula from 1983 onward were sent detailed postal questionnaires on sexual function and quality of life. Each respondent was age and gender matched to 3 controls randomly selected from the general population. Penoscrotal/gynecologic abnormalities were obtained from the records.

RESULTS

A total of 41 patients (62%) with a median age of 22 years participated in the study. Of the patients 20 were males with rectourethral fistula (prostatic in 60%), 10 were females with vestibular/perineal fistula and 11 were males with low malformations. Although experience of sexual relationships and orgasmic function were reported in comparable proportions to controls, age at coital debut was significantly delayed in all groups of patients (p ≤0.046). Erectile function was preserved after sagittal repair but absent ejaculations or azoospermia affected 3 males with rectourethral fistula (15%). Penoscrotal/gynecologic abnormalities affected 12% of patients. Overall quality of life scores were comparable to controls but a trend was found for lower scores on emotional items in males with rectourethral fistula (p = 0.06) and for a negative effect on sexual life in females (p = 0.03).

CONCLUSIONS

While erectile and orgasmic function appear preserved after sagittal repair, further evaluation of fertility issues in males with rectourethral fistula is indicated. Larger multicenter studies are needed to confirm our findings.

Epidydimo-orchitis and anorectal malformations: when and in whom?

PURPOSE

Epididymo-orchitis (EO) is infrequently reported in anorectal malformation (ARM) cases. Therefore, it is difficult to assess its risk factors.

METHODS

A total of 110 male patients who were operated on for ARM at the same Institution over a period of 13 years were contacted. Association was assessed between EO and the following: spinal dysraphism (SD), symptomatic VUR (VUR), and bowel management (BM) requiring enemas. The data were analyzed with the Chi-square test.

RESULTS

A total of 89 patients were contacted. Ten cases of EO were found, and all occurred in patients with recto-urethral (RU) fistula after reconstruction. The patients' age at first episode ranged between 4 and 11 years. RU fistula patients experiencing EO (Group A, 10 patients) were compared with those without EO (Group B, 33 patients). VUR occurred in 9/10 cases in Group A and in 13/33 cases in group B (Chi-square 7.8658, p = 0.005038). SD was present in 4/10 cases in group A and in 13/33 cases in Group B (Chi-square 0.0434, p = 0.83491). A total of 8/10 cases in Group A and 12/33 cases in Group B were on BM (Chi-square 5.87, p = 0.0015).

CONCLUSIONS

EO occurs in approximately in 20 % of male cases with ARM, and recto-urinary communication and should be considered the primary diagnosis in the presence of testicular pain. This could avoid unnecessary surgical exploration, and the family should be counseled about this subject.

Long-term outcomes of anorectal malformations

Anorectal malformations (ARMs) and cloacal anomalies are rare and complex malformations of the lower gastrointestinal and genitourinary tracts. They affect approximately 1 in 3,500 live births. The treatment of these patients has traditionally focused on achieving urinary and faecal continence, with preservation of renal function. With improved surgical techniques and paediatric intensive care facilities, these patients now live relatively normal lives, with a near-normal life expectancy. Comparing results reported by different surgeons is difficult because a wide range of terminology is employed to describe the anomalies encountered. This paper attempts to simplify some of the reported outcomes of bowel function to allow a more direct comparison between groups. Urinary outcomes were not so easily comparable due to the disparity in assessing patient outcomes. Therefore, before a global analysis of all groups can take place, a standardised terminology will be necessary. At present there is a gap in the published literature of comprehensive follow-up in this group of patients, particularly regarding reproductive and sexual functioning. More detailed information on long-term outcomes is needed in these patients to facilitate informed decision-making by the primary physician (usually the paediatric surgeon) and the parents on behalf of their child.

Epididymitis in infants with anorectal malformation

OBJECTIVE

To document the characteristics of epididymitis in boys with anorectal malformations.

METHODS

Sixty-six boys with anorectal malformation were treated between January 1990 and January 2000, in our center. Four of these boys experienced epididymitis attacks. The first three patients had rectourinary fistula and the fourth had a low type anorectal malforation without a rectourinary fistula.

RESULTS

Patients were followed up for seven to nine years and epididymitis did not recur after the definitive operation in the first three patients. The fourth patient had four other episodes of epididymitis postoperatively and no reason for these episodes could be found during the further urological evaluation. Two patients had urinary tract infection and one patient had urinary tract contamination during their episodes of epididymitis.

CONCLUSION

The cause of the epididymitis can be anorectal malformation with rectourethral fistula itself or another urogenital anomaly that is associated with anorectal malformation. There is a relationship between urinary tract infection and epididymitis in these patients.

Aspermia and chronic testicular pain after imperforate anus correction. Cryopreservation of sperm cells extracted from whole orchiectomized testis: case report

This paper describes an unusual association of aspermia and untreatable, chronic testicular pain in a young man who underwent 14 surgical interventions for an imperforate anus. Physical examination and ultrasonography revealed left epididymal and vas enlargement, normal-sized testes, tubular ectasia of the left rete testis and a small intraprostatic paramedian left cyst. Retrograde ejaculation and urogenital infections were excluded, and the FSH and karyotype results were normal. The patient gave his consent to an exploratory intervention with possible radical left orchiectomy. The patency of the left distal seminal duct was unexpectedly normal, and no sperm were found in the epididymis or vas deferens despite their obstructive appearance. Sperm were only found in a 'testicular touch' preparation. The removed testis was immediately opened and most of the testicular lobules were removed, thus allowing the extraction of 25 x 10(6) sperm, which were cryopreserved in 35 straws. An 8-month follow-up examination documented the complete absence of pain and, during the next few months, it is planned to use the thawed sperm for ICSI. Radical orchiectomy plus the cryopreservation of sperm extracted from the whole testis must be considered in the case of the co-existence of chronic unilateral testicular pain and aspermia.

Ejaculatory physiology and dysfunction

The sequence of events encompassing ejaculation has been well described. Multiple disease processes can result in ejaculatory dysfunction. Evaluation and subsequent treatment of ejaculatory dysfunction is possible using behavioral, mechanical, and medical and surgical modalities. Further elucidation of ejaculation is now taking place at the molecular level.
