OBJECTIVE: This study aimed to investigate the rate of re-ascent requiring re-operation after primary orchidopexy and to investigate eventual differences between the inguinal and scrotal approach as well as other potential predictors for re-ascent.
METHODS: A retrospective cohort study of children treated for undescended testis (UDT) with orchidopexy between 2018 and 2022 was conducted. The primary outcome was re-ascent requiring re-operation, and the secondary outcome was atrophy rate. Independent variables were age, underlying conditions, side, surgical approach, operation time, bilaterality, congenital/ascended UDT, presence of scrotal hypoplasia, presence of a patent processus vaginalis, division of external oblique, and suture of the testis. Univariate and logistic regression were used to evaluate differences between groups and risk for re-ascent.
RESULTS: A total of 662 testes in 554 patients were included. Re-operation occurred in 6% (7% with inguinal approach, 3% with scrotal approach, p = 0.04). Re-operation was associated with younger age, congenital UDT, and inguinal approach, but neither of these variables remained significant in multivariate analyses. Atrophy occurred in one testis.
CONCLUSIONS: The rate of re-ascent was 6% and the atrophy rate was 0.15%. A larger study may find predictors for re-ascent but with very low absolute risk. The lower rate of re-ascent with the scrotal approach is probably due to selection bias.

This case report presents a rare case of adult cryptorchidism, found incidentally in a 25-year-old gentleman who initially presented with abdominal and suprapubic pain and was successfully treated with staged orchidopexy. To our knowledge, to date, our case is the first published instance of bilateral cryptorchidism in an adult presenting with nonspecific suprapubic pain. Cryptorchidism is the most common genital abnormality in newborn boys, and due to its association with an increased risk of infertility and malignancy, current management involves surgical correction with orchidopexy by 12 to 18 months of life. Adult presentation of cryptorchidism is very unusual due to early intervention; therefore, bilateral cryptorchidism is even more rare. As a result, current guidelines do not address proper management for adult cryptorchidism. Therefore, after performing a thorough review of the literature on contemporary guidelines for cryptorchidism management, we aim to highlight our approach to management in this rare case of adult bilateral cryptorchidism. We suggest bilateral orchiectomy as the safest option, if the patient is amendable, or bilateral orchiopexy with long-term follow-up for testicular cancer. Although the American Urological Association guidelines recommend orchiectomy for postpubertal cryptorchid children, currently, no explicit guidelines exist for the preferred method of managing adult cryptorchidism. Due to the increased risk of infertility and testicular cancer with cryptorchidism, orchiectomy instead of orchiopexy may be the preferred surgical approach in some instances. Still, in the case of bilateral cryptorchidism, orchiectomy may not always be the most viable solution, making orchiopexy with long-term follow-up for testicular cancer the best option, such as in our case.

BACKGROUND: Urine drug testing (UDT) plays a significant role in monitoring patients on chronic opioid therapy (COT) for non-medical opioid use (NMOU). UDT, at times, can be inconsistent and misleading. We present a case where a patient on a buprenorphine patch had false negative results.
METHODS: A female in her 70s with metastatic breast cancer presented with uncontrolled pain from a T6 compression fracture. She had no relief with tramadol 50 mg every 6 hours as needed. Due to an allergic reaction to hydromorphone, our team prescribed a buprenorphine patch of 5 μg/h. Subsequently, she expressed excellent pain control, and the clinician confirmed the patch placement on examination. She underwent a UDT during the visit. The UDT was negative for both buprenorphine and its metabolites. The literature review showed that false negative UDT results are relatively common among patients with low-dose buprenorphine patches. The combination of a thorough physical examination, a review of the Prescription Drug Monitoring Program, and reassuring scores on screening tools placed her at low risk for NMOU.
CONCLUSIONS: Buprenorphine has a ceiling effect on respiratory depression and a lower risk for addiction. However, when used in low doses, the drug might not have enough metabolites in the urine, leading to a false negative UDT. Such results might affect patient-physician relationships.
CONCLUSIONS: In addition to the UDT, a thorough history, screening for NMOU, physical exam, a review of PDMP, and a good understanding of opioid metabolism are necessary to help guide pain management.

Undescended testis is most common congenital malformation in boys. Most common location is inguinal canal but rarely it is found in intraabdominal. 10% of them will grow become mass if left untreated. This case report describes cases of men of 40s with unilateral UDT and not noticeable until they felt heavy and feel palpable mass in abdomen revealed as seminoma. He is sterile and not be able to reproduce. Chemotherapy was done and the response was remarkable. This case report reiterates the need for a scrotal examination in men presenting with an abdominal mass, so as to rule out an intra-abdominal seminoma.

UNASSIGNED: Undescended testis (UDT) is a common congenital urogenital anomaly that is treated by orchiopexy. We aimed to introduce patent processus vaginalis (PPV) sac tightening (PVST) technique and compare it to the conventional technique.
UNASSIGNED: We retrospectively studied all the operated UDT patients during 10 years. In the conventional technique, it was necessary to ligate PPV sac after being peeled off from the spermatic cord. PVST was dissected longitudinally from the two sides of where the PPV sac wall was attached to the spermatic cord till the proximal part, and only a narrow thin layer sticking to the spermatic cord was left and the proximal PVV sac opening was tightened as much as possible with vicryl suture at the internal inguinal ring level. The significance level was <0.05.
UNASSIGNED: Of 821 orchiopexy (mean age 24.5±24.2 months), 36.3% were done by conventional and 63.7% by PVST technique. Hematoma, edema, hydrocele, and wound infection were lower in the PVST technique, but it was not significant (p>0.05). Testicular atrophy and operation time were significantly lower in the PVST than the conventional technique (p<0.001).
UNASSIGNED: The orchiopexy PVST technique has lower complications and seems to be easier, faster and safer than the conventional technique.

Treating chronic pain is complicated. Primary care doctors and others are called on to treat the vast majority of patients with pain, to do so in brief visits and to do it safely. This is a tall order, but it is possible to do it well when the proper tools are employed to aid the clinician in diagnosing and monitoring the patient. Among these tools, the one that has been most useful is urine drug testing. Prescribers can perform presumptive screens with the immunoassay method in my office, but this method has limitations in accuracy and specificity and sensitivity. When medically necessary, it makes sense to seek definitive testing from the laboratory to confirm results of immunoassay tests with chromatographic testing and/or when there is the possibility of a false negative in the office. These \"false negatives\" are extremely common, with patients using nonprescribed opioids and illicit medications often go undetected if one were to stop at the office-based result. These patients are in danger of addiction and overdose, and this added information is crucial in efforts to treat pain and avoid these complications.

Recent upward trends in the prevalence of abuse of prescription drugs and illicit substances have resulted in increased demands for toxicology testing to support the emergency department and drug treatment in pain management programs. This review will discuss the challenges faced by clinical laboratories to manage the utilization of toxicology tests, particularly those ordered in managing poisoned patients in the emergency department and chronic pain patients on opioid therapy. Optimal utilization of toxicology tests to support the emergency department relies on selecting the appropriate tests for the patient, and the availability of the results in a timely fashion. Two tiers of toxicology testing systems with different requirements for turnaround time will be discussed. In patients with chronic pain urine drug testing, including screening and confirmation testing are used extensively in pain management to monitor patient compliance. A thorough understanding of the performance characteristics of the test methodologies and drug metabolism is a key to making a proper analytical and clinical interpretation of the test results and will contribute to effective utilization of these tests. In addition, the reimbursement system is an important factor in the decision making process for test selection utilization as significant costs can be incurred by both payers and patients. Collaboration, trust, and effective communication among clinicians, patients, and clinical laboratory professionals are essential for effective utilization of toxicology testing.

OBJECTIVE: Undescended testis is the most common defect in male newborns. This condition is associated with increased risks of infertility and testicular malignancy due to abnormal germ cell development in the testes. Early surgery may limit such risks. We analyzed germ cell development vs age at orchiopexy using a germ cell marker and a Sertoli cell marker on testicular biopsies.
METHODS: A total of 22 testicular biopsies at orchiopexy in 20 patients 5 to 24.5 months old were fixed and embedded in paraffin. Sections were processed and labeled with AMH antibody for Sertoli cells and MVH antibody for germ cells for immunofluorescent histochemical analysis. Confocal images were counted using ImageJ (National Institutes of Health, Bethesda, Maryland) for germ cells and testicular tubules. The data were analyzed using linear regression.
RESULTS: Sertoli cells were clearly distinguished from MVH positive and negative germ cells located centrally or on basement membranes of tubules. Percentage of tubules with MVH negative germ cells significantly decreased with increasing age at orchiopexy (β = -0.03, p = 0.03). Total tubular numbers and \"empty\" tubules without germ cells significantly increased with age at orchiopexy (β = 1.15, p = 0.02 and β = 0.44, p = 0.04, respectively).
CONCLUSIONS: AMH antibody distinguished Sertoli cells from germ cells, and MVH antibody distinguished 2 types of germ cells at different developmental stages. Biopsy at orchiopexy in older patients showed significant germ cell depletion. These results lend support to early surgery to optimize germ cell number.

OBJECTIVE: We determined relative semen quality in youths diagnosed with cryptorchidism or varicocele as a surrogate for ultimate paternity potential. We hypothesized that youths with varicocele would be at lower risk for subfertility based on semen analysis than their counterparts with surgically corrected cryptorchidism.
METHODS: We retrospectively reviewed the records of patients with a history of cryptorchidism or varicocele. Patients were placed in 1 of 3 groups based on diagnosis, including group 1-untreated varicocele, group 2-treated bilateral cryptorchidism and group 3-treated unilateral cryptorchidism. Age and semen parameters (density, volume, count, motility and total motile count) were compared for each group.
RESULTS: A total of 193 subjects were studied. Median age was 18.3 (IQR 18.1-19.3), 18.6 (IQR 18.3-21.0) and 18.5 years (IQR 18.2-19.6) in the 76 group 1, 21 group 2 and 96 group 3 patients, respectively. Total motile count in groups 1, 2 and 3 was 14.6 (IQR 4.7-29.3), 4.0 (IQR 0-38.0) and 34.1 million sperm (IQR 7.6-90.8), respectively. No significant difference existed between the groups in age, volume (p = 0.106) or motility (p = 0.197). However, density (p = 0.0001), count (p = 0.0001) and total motile count (p = 0.0002) achieved significance. For each of these parameters a significant difference was noted for group 1 vs 3 and group 2 vs 3 but not for group 1 vs 2.
CONCLUSIONS: The semen quality of youths with varicocele more closely resembles that of youths with bilateral cryptorchidism than those with unilateral cryptorchidism. This is concerning and should challenge current treatment paradigms for adolescents with varicocele.
