Objective: To conduct a translation and validation study of the Chronic Orchialgia Symptom Index (COSI), which has 12 questions in three domains pain (P), sexual symptoms (SS), and quality of life (QoL), in the Turkish language., Material and Methods: The study included a total of 175 patients diagnosed with chronic scrotal content pain (CSCP) between January 2023 and January 2024. In addition to demographic data, the scores obtained on the COSI questionnaire and Visual Analog Scale (VAS) were recorded. Internal consistency was assessed using Cronbach alpha coefficients. Reliability was evaluated using the test-retest correlation method., Results: The mean age of the patients was 37.2 ± 14.1 years and the median (IQR) duration of pain was 5.5 (9) months. The median total COSI score was determined as 13 (13) and the median subscores were 7 (7) for P, 1 (2) for SS, and 5 (6) for QoL. The test-retest correlation coefficient for each item was determined to be higher than r  = 0.80 ( p  < 0.001). The Cronbach alpha values for the subscores were 0.80 for P, 0.71 for SS, and 0.80 for QoL. There was determined to be a statistically significant positive correlation between the VAS score and the COSI P, SS, QoL, and total scores ( r : 0.63, p  < 0.001; r  = 0.32, p  < 0.001; r  = 0.56, p  < 0.001; r  = 0.59, p  < 0.001, respectively). The optimal cutoff point of the COSI total score was determined to be 16.5 points (AUC:0.77, p  < 0.001) for the determination of patients experiencing severe pain (⩾ 7.5) according to the VAS score., Conclusion: The Turkish version of the COSI questionnaire is a valid, reliable, and repeatable questionnaire that can be used to evaluate the effects of symptom severity in patients with CSCP., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: The management of chronic groin and scrotal content pain (orchialgia) is a complex condition after varicocelectomy that is encountered by most practicing clinicians. The aim of this study was to evaluate the effectiveness of low-level laser therapy (LLLT) in orchialgia after varicocelectomy surgery. Methods: This study was performed as a double-blind, placebo-controlled randomized clinical trial in which sixty patients with orchialgia after varicocelectomy were randomly divided into three groups of 20 as follows: (1) low-level laser group with red (650 nm, 50 mW), (2) low-level laser group with infrared (IR) (820 nm, 100 mW), and (3) laser placebo group. The treatment protocol consisted of 15 minutes, three times a week, for only 12 sessions. Then, the patients were evaluated for pain and sexual satisfaction during the 12-week follow-up. Results: The pain score in the two groups of low-level laser with red light and IR spectra showed a significant relief ( P <0.05) 6 and 12 weeks after starting the treatment, In addition, a significant increase was observed in the level of sexual satisfaction in the red and infrared spectra LLLT groups ( P <0.05). Conclusion: We concluded that the use of LLLT with red light (650 nm, 50 mW)/IR (820 nm, 100 mW) spectra with power of 6-25 J/cm 2 /day in 15 minutes, three times a week, for 12 sessions can significantly reduce pain and increase sexual satisfaction in these patients., Competing Interests: The authors claim no conflict of interest., (Copyright © 2024 J Lasers Med Sci.)

The objective was to assess whether men suffering from testicular retraction secondary to hyperactive cremaster muscle reflex have an anatomic difference in the thickness of the cremaster muscle in comparison to men who do not have retraction. From March 2021 to December 2021, 21 men underwent microsurgical subinguinal cremaster muscle release (MSCMR) on 33 spermatic cord units, as 12 of them had bilateral surgery, at Surgicare of South Austin Ambulatory Surgery Center in Austin, TX, USA. During that same time frame, 36 men underwent subinguinal microsurgical varicocele repair on 41 spermatic cord units, as 5 were bilateral for infertility. The thickness of cremaster muscles was measured by the operating surgeon in men undergoing MSCMR and varicocele repair. Comparison was made between the cremaster muscle thickness in men with testicular retraction due to a hyperactive cremaster muscle reflex undergoing MSCMR and the cremaster muscle thickness in men undergoing varicocele repair for infertility with no history of testicular retraction, which served as an anatomic control. The mean cremaster muscle thickness in men who underwent MSCMR was significantly greater than those undergoing varicocele repair for infertility, with a mean cremaster muscle thickness of 3.9 (standard deviation [s.d.]: 1.2) mm vs 1.0 (s.d.: 0.4) mm, respectively. Men with testicular retraction secondary to a hyperactive cremaster muscle reflex demonstrate thicker cremaster muscles than controls, those undergoing varicocele repair. An anatomic difference may be a beginning to understanding the pathology in men who struggle with testicular retraction., Competing Interests: None

Introduction: The management of chronic scrotal pain is long and varied, with historical treatment algorithms typically ending with orchiectomy. Microsurgical denervation of the spermatic cord (MDSC) is a testicle-sparing option for patients who have failed conservative treatment options and over its forty-year history has seen many technical refinements., Objectives: To review the history and development of MDSC and discuss the outcomes of different surgical techniques., Methods: A literature review using PubMed and Google Scholar was conducted to identify studies pertaining to surgical treatment of CSP, MDSC, and outcomes. Search terms included "chronic," "scrotal pain," "orchialgia," "spermatic cord," "denervation," and "microsurgery.", Results: We included 21 case reports and series since the first seminal paper describing MDSC technique in 1978. Additional studies that challenged existing conventions or described novel techniques are also discussed. The current standard procedure utilizes a subinguinal incision and a surgical microscope. Open, robotic, and laparoscopic approaches to MDSC have been described, but access to minimally invasive instruments may be limited outside of developed nations. Pain reduction following preoperative spermatic cord predicts success of MDSC. Methods for identifying and preserving the testicular and deferential arteries vary depending on surgeon preference but appear to have comparable outcomes. Future developments in MDSC involve targeted denervation, minimizing collateral thermal injury, and alternative techniques to visualize arterial supply., Conclusion: For patients suffering from CSP, MDSC is a well-studied technique that may offer appropriately selected patients' relief. Future investigation comparing targeted vs full MDSC as well as in vivo study of new techniques are needed to continue to improve outcomes. Sun HH, Tay KS, Jesse E, et al.

The management of pain is a complex condition that will be encountered by most practicing clinicians. In the genitourinary community, testicular pain may be classified as acute or chronic. Initial evaluation of chronic groin and scrotal content pain (CGSCP) begins with a detailed history and physical examination to elucidate the presenting pathology. Multiple therapy algorithms have been proposed with no definitive consensus; however, most begin with conservative intervention and medical management prior to advancing to more invasive procedures. Surgical approaches may range from reconstruction, as in vasovasostomy for post-vasectomy pain syndrome, to excision of the offending agent, as in epididymectomy. This review seeks to focus on chronic pain in the genitourinary community and review techniques of pain management in the current intervention for orchialgia, as well as identify future methods of treatment., Competing Interests: Conflict of interest statement: The author(s) declare that there is no conflict of interest., (© The Author(s), 2021.)

Chronic orchialgia can be the result of pathological processes of the scrotal contents or stem from non-intrascrotal structures. Successful pain management depends on identifying the source of localized or referred pain. This is a case report of a 39-year-old male sports coach who presented with low back pain, right orchialgia, and sciatica refractory to conservative management. Magnetic resonance (MR) imaging revealed disc protrusion at L3/L4 and L4/L5 levels. Positive outcomes in relieving back and testicular pain were obtained after a total of 30 chiropractic sessions over a 9-week period. The evidence of the subjective improvement was corroborated by regression of the herniated discs documented on the repeat MR imaging. While chronic orchialgia is not an uncommon problem for men of all ages, it has seldom been described in association with lumbar discogenic disease. The current study provided preliminary support for a link between orchialgia and lumbar disc herniation. Chiropractic manipulation had provided a mechanistic alleviation of noxious lumbar stimuli, leading to symptomatic and functional improvements.

Purpose: Laparoscopic living-donor nephrectomy (LLDN) is the gold-standard procedure for kidney procurement. Ipsilateral orchialgia has barely been described. Some authors reported that ligation of gonadal vein (GV) above iliac vessel bifurcation could prevent orchialgia. We aimed to assess incidence and duration of orchialgia after LLDN in male donors despite distal ligation of GV., Methods: Patients who underwent LLDN from 2014 to 2017 were included. Standard procedure consisted in distal ligation of GV, close to the renal vein confluence and proximal ureteral ligation. Patients' demographics, per-operative data, and post-operative consultation reports were retrospectively reviewed. Orchialgia and scrotal symptoms were assessed through a non-validated questionnaire by phone interview., Results: Sixty-nine donors were included. Orchialgia incidence and testicular swelling were 31.9% (n = 22) and 15.9% (n = 11), respectively. Median symptom duration was 15.5 months. Orchialgia led to medical consultation in 41.7% (n = 10) of cases. All patients declared having been informed, prior to donation, about possible residual pain but not specifically orchialgia., Conclusion: Orchialgia after LLDN affects more than 30% of donors, despite distal ligation of GV and led less than 50% of them to medical consultation, suggesting a large underestimation in clinical practice. Emphasis should be put on this complication during pre-donation information.

Chronic scrotal pain (CSP) is a common and poorly understood medical condition that significantly affects individuals' quality of life. Many patients seek evaluation and management of their symptoms from multiple physicians. Our review aims to address diagnostic modalities, clinical evaluation, and surgical and non-surgical management. We conducted a computerised detailed search of the PubMed, Medline, Embase and Cochrane databases for reports pertaining to CSP using the Medical Subject Headings keywords 'chronic scrotal pain', 'testicular pain' and 'orchialgia', and we included in the review those that fulfilled the inclusion (adult male with CSP presenting with the criteria of CSP ) and exclusion (extra-scrotal pain) criteria. After the direct causes of CSP were identified by reviewing the clinical evaluations (history taking and examination are mandatory) and the diagnostic evaluations (urine analysis is crucial and ultrasound can be helpful), the most-used medical and non-surgical treatments for CSP were tricyclic antidepressants (success rate of up to 66.6%) and spermatic block (success rate of more than 90%), and the most-used surgical procedure was microsurgical denervation of the spermatic cord (success rate of up to 70%). The evidence currently available remains rare and of low quality, making it difficult to strongly recommend individual treatment options. However, multimodal treatment modalities using physical therapy and psychotherapy may help patients and provide useful tools for coping with this condition. There are also useful non-surgical and surgical options for CSP that depend on the patient's state, the severity of the complaint and what options have already been tried., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Moubasher et al.)

Background: To describe our institutional outcomes with microscopic spermatic cord denervation (MSCD) for chronic scrotal content paint (CSCP) and identify predictors of treatment failure., Methods: Retrospective chart review was performed to identify all MSCD performed by two surgeons at a single institution from 2010-2019. Patient demographic data and operative outcomes were collected. Patients were excluded from analysis if no post-operative follow up was available. Success was defined as complete resolution of bothersome pain. Multivariable logistic regression was utilized to identify predictors of treatment failure., Results: During the study period, 101 patients were identified in which 113 MSCD procedures were performed. Final analysis included 103 procedures across 93 patients. Mean age was 41.8 years (SD 13.2), mean BMI was 29.2 kg/m 2 (SD 5.96) and median months of pain preceding surgery were 24 (range, 3-300 months). Overall, 75/103 (73%) MSCD were successful. Of the failures, 5 patients had recurrence of pain greater than 6 months after surgery. Only the presence of pelvic floor muscle spasm (PFMS) independently predicted MSCD failure (OR 3.95, P=0.02). 9 of 19 (47%) patients with PFMS experienced treatment failure, while 19 of 84 (23%) without PFMS experienced failure., Conclusions: MSCD offers a therapeutic option for patients with refractory CSCP. The presence of PFMS is associated with lower surgical success rates. Patients with pre-operatively identified PFMS should be counseled regarding a higher risk of treatment failure., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/tau-20-561).

Smooth muscle hyperplasia of the testicular adnexa (SMH-TA) is a rare mass-forming intrascrotal lesion. Although benign, it can be a diagnostic challenge, as we have seen in our consult practice. Herein, we discuss our experience with these lesions over 14 years. Twelve SMH-TA cases were identified in our institutional records between 2005 and 2019. The morphologic features were reviewed. Clinical information was obtained from physicians' notes. The mean age was 51 years (range, 24-82 years). Six cases were on the left side, five on the right, and one was bilateral. The most common presentations were orchialgia (n = 10) and mass (n = 6). Two patients had a concurrent incarcerated inguinal hernia, and one had a recent groin trauma. Past medical history included 5 patients with previous surgeries in the inguinal region, 2 with a history of treated infections, and 1 with persistent chronic orchitis. Eight patients have undergone ultrasound imaging which showed lesions (n = 4), hematoma (n = 1), undescended testis (n = 1), or no abnormalities (n = 2). Grossly, the mean size was 1.7 cm (range, 1.0-3 cm). The lesions had ill-defined, focally cystic, pink-tan nodular surface. Microscopically, the lesions were comprised of an ill-defined smooth muscle proliferation arranged in fascicles or haphazard fashion, growing in a periductal, perivascular, interstitial, or most commonly in a mixed pattern. SMH-TA is a rare benign entity that can present clinically as orchialgia and/or a suspicious intrascrotal mass. As suggested in previous studies, we believe that this lesion represents a reactive process., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Introduction: Thoracolumbar dysfunction (TLD) had been evoked as a possible etiology of chronic testicular pain. Our study investigated the efficacy of osteopathic diagnosis and treatment of TLD in men with chronic testicular pain., Methods: Patients suffering from testicular pain were examined for thoracolumbar dysfunction and enrolled in a prospective trial if they have both conditions. Following standardized examination, all patients were prescribed 1 to 3 osteopathic treatment sessions, usually at weekly interval. Treatment success was evaluated using the Visual Analog scale and durability was assessed by regular follow-up. Patient satisfaction was also assessed. Comparison of pain improvement was done using Wilcoxon matched-pairs signed-ranks test. Logistic regression was used to assess for risk factors of success. A P<0.001 was used for significance., Result: Out of 62 patients enrolled, 41 patients (median age 32 years, IQR 24-37) were suffering from chronic testicular pain and TLD. 37 of the 41 participants completed the treatment and follow-up according to the plan. Patients underwent a median of 2 osteopathic treatment sessions (range 1-3). Overall, pain disappeared completely in 25 patients (67.5%) and improvement was noted in 7 patients (18.9%). After initial improvement, two patients experienced relapse at their last visit (5.4%). Five patients (13.5%) had no improvement of their symptoms after osteopathic treatment. Statistically, improvement was significant with a P<0.001 and on logistic regression, site of pain and duration of pain were the sole predictors of failure., Conclusion: TLD is a pathology that should be considered in the differential diagnosis in patients with chronic testicular pain and osteopathic manipulation of the spine appears to be an effective treatment option., (Copyright © 2019 Elsevier Masson SAS.

A careful history and evaluation of men with chronic orchialgia elucidates the aetiology in some men to be a hyperactive cremaster muscle reflex with testicular retraction as the cause. The objective is to evaluate outcomes in men who underwent microsurgical subinguinal cremaster muscle release (MSCMR) with a retrospective chart review between September 2011 and April 2019. Nineteen men with hyperactive cremaster muscle reflex in 25 spermatic cord units underwent MSCMR, six bilateral and thirteen unilateral. Candidacy for MSCMR included answering yes to the question: "at times of testicular pain, does the testicle retract up in the groin to the extent that you have to milk it back down to the scrotum?", normal digital rectal examinations, negative urinalyses, negative scrotal Doppler ultrasounds, vigorous retraction of testis with Valsalva on examination and pain without an anatomic or pathologically identifiable aetiology except testicular retraction. Of the men who underwent MSCMR, 100% (25/25) of spermatic cord units had resolution of testicular retraction and 92% (23/25) of spermatic cord units had complete resolution of orchialgia. There was one complication, a small scrotal hematoma which resolved. MSCMR is an effective option for men with orchialgia secondary to testicular retraction due to a hyperactive cremaster muscle reflex., (©2019 The Author.

Objective: Treatment of chronic idiopathic scrotal pain is a dilemma and challenge. Many men with this condition undergo multiple therapies and surgeries with no improvement in their symptoms. Patients with interstitial cystitis/bladder pain syndrome (IC/BPS) have a variable clinical presentation and initially complain of only one symptom of urinary urgency, frequency, or pain. We report on patients with chronic idiopathic scrotal pain treated with standard therapy for IC/BPS., Patients and Methods: Patients with chronic idiopathic scrotal content pain were evaluated, determined to have chronic idiopathic scrotal content pain, and were treated with either pentosan polysulfate sodium (PPS) or bladder instillations of alkalinized lidocaine and heparin., Results: Sixteen males were determined to have chronic idiopathic scrotal pain. Eight males received PPS and eight males received a bladder instillation of alkalinized lidocaine and heparin. All patients had improvement of their scrotal pain to a self-reported acceptable level., Conclusions: Chronic idiopathic scrotal pain may be one of the variable presenting symptoms of IC/BPS. This scrotal pain may actually be referred pain from the bladder. Standard therapies for IC/BPS may be a treatment option for chronic idiopathic scrotal pain., Competing Interests: There are no conflicts of interest.

Objective: To explore the expression of the N-methyl-D-aspartate (NMDA) receptor in the rat model of orchialgia and its possible mechanisms., Methods: According to Yoshioka's method, the male rats in the control group were injected with 0.2 ml saline, and those in the experimental group with 0.2 ml 2% acetic acid solution. Then we tested the behavioral responses of the rats and determined the expressions of the subunits NR1 and NR2B of the NMDA receptor in the dorsal root ganglion and spinal dorsal horn by Western blot, RT-qPCR and immunofluorescence staining., Results: The withdrawal latency was decreased in the model rats, reaching the lowest value at 4 hours after modeling, significantly lower than in the controls (［4.15 ± 0.84］ vs ［12.32 ± 1.05］, P < 0.05). Compared with the controls, the model rats showed remarkably increased mRNA and protein expressions of NR2B in the dorsal root ganglion (P < 0.05) but not in the spinal dorsal horn at 4 hours. However, no statistically significant difference was found in the expression of NR1 either in the dorsal root ganglion or in the spinal dorsal horn between the two groups (P > 0.05)., Conclusions: The NMDA receptor plays an important role in pathogenesis of orchialgia in rats. In the early stage of pain, upregulating the expression of the subunit NR2B of the NMDA receptor can mediate peripheral hyperalgesia and consequently orchialgia.

Background: Chronic testicular pain (orchialgia) has been defined as intermittent or constant unilateral or bilateral testicular pain that lasts 3 months or longer, significantly interfering with daily activities, and prompting the patient to seek medical attention. In many instances, the etiology of the pain is not identified. The contribution of psychological factors is unclear. The purpose of this study was to identify the categories of mental health (MH) diagnoses that are most frequently associated with orchialgia and determine if a correlation exists between MH diagnoses and orchialgia., Methods: A retrospective review was performed to identify all adult patients within the San Antonio Military Health System with a new diagnosis of orchialgia from January 2005 to April 2015. Patients with acute pathology or recent inguinal/scrotal surgery were excluded. A comparative cohort of all men presenting with hydroceles within the same timeframe was obtained. The presence of coexisting MH diagnoses in both cohorts was then determined., Results: Four hundred and forty-four men met the inclusion criteria for orchialgia, with 133 men presenting with hydroceles. The incidence of orchialgia increased significantly over the study period (P=0.001). MH diagnoses in the study population did trend upward over the years, but not significantly (P=0.063). MH diagnoses were not significantly higher in the cases compared to the controls (21.6% vs. 18.8%, P=0.479). The prevalence of anxiety was twice as high in the cases (9% vs. 4.5%), though not significantly (P=0.075). The prevalence of all MH diagnoses was significantly higher than in the general US population based on National Institute of Mental Health statistics., Conclusions: The incidence of orchialgia rose significantly over time, but it was not significantly associated with MH diagnoses. These results may also be skewed by the overall higher percentage of MH diagnoses in the study population than in the general population., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Chronic scrotal content pain (CSCP) refers to bothersome pain localized to structures within the scrotum that has been present for ≥ 3 months. Etiologies include infection, trauma, and referred pain from the spine, abdomen, and retroperitoneum. However, in many patients there is no obvious identifiable cause. The initial evaluation should include a thorough history and physical examination with adjunctive imaging and laboratory tests as indicated. Treatments vary based on the underlying etiology and include both nonsurgical and surgical options with high levels of success when selectively utilized. The spermatic cord block with local anesthetic is an important tool that helps identify those patients who may benefit from surgery such as microscopic denervation of the spermatic cord. Other treatments including pelvic floor physical therapy may also be indicated in specific circumstances. Using a thoughtful and thorough approach to evaluation and treatment of CSCP, urologists can work with patients to achieve significant improvements in quality of life., (© 2019 MedReviews®, LLC.)

Objectives: Microsurgical denervation of the spermatic cord (MDSC) is a treatment option for chronic orchialgia (CO) refractory to conservative treatment. Studies showed specific nerve fibers as the possible cause of CO. We aimed to present the outcomes of ligation of these nerves using targeted MDSC., Methods: We retrospectively reviewed 30 cases who underwent targeted MDSC from August 2014 to February 2018. Patients included were under strict criteria. Pain was assessed preoperatively and postoperatively using a subjective visual analog scale (VAS) and objectively with the standardized and validated Pain Impact Questionnaire-6 (PIQ-6) score., Results: Data were available on 28 cases at repercussion. During a median follow-up of 12 months (range 10-29), 25 cases (89.2%) showed a significant reduction in pain and 3 (9.8%) had no change in pain by subjective VAS scoring. Of cases with a significant reduction in pain, 15 (53.5%) had complete resolution and 19 (67.9%) had a 50% or greater reduction. Objective PIQ-6 analysis showed a significant reduction in pain in 78.6% of patients at 6 months postoperatively, in 82.1% at 1 year, in 82.1% at 2 years., Conclusions: Targeted MDSC is an effective, minimally invasive approach with potential long-term durability in patients with refractory CO., (© 2019 S. Karger AG, Basel.)

Background: The purpose of this study was to develop a candidate symptom index for men with an established diagnosis of chronic orchialgia., Methods: Based on interviews with patients and providers, we developed a 70-item questionnaire that focused on seven areas of orchialgia symptoms: pain, location, urinary symptoms, sexual dysfunction, medical history and quality of life (QOL) impact. The questionnaire was completed by patients at two medical centers. Cluster analysis was performed with the software package R (3.2.1)., Results: A total of 113 men completed the survey. Median symptom duration was 12 months (range, 3-336 months). Outside the testicle, pain was felt in the spermatic cord (66%), groin (66%), penis (24%), suprapubic region (38%), flank (31%), thigh (32%), abdomen (36%) and perineum (35%). Bother scores were high only for testicle and spermatic cord pain. Urinary frequency was common (54%) but not bothersome. Sexual dysfunction was common: 55% had erectile dysfunction, 56% had decreased libido and 39% had painful ejaculation with high bother for all. By cluster analysis, QOL parameters clustered tightly with minimal pain level, pain at night, burning pain, distribution to spermatic cord and groin, erectile dysfunction and premature ejaculation., Conclusions: Men with chronic orchialgia have a high incidence of associated symptoms. Most bothersome symptoms with highest QOL impact include burning pain, pain at night, radiation to groin and spermatic cord, erectile dysfunction and low libido. Based on these findings, we have created a candidate orchialgia symptom index with domains of pain, sexual symptoms and QOL that will undergo prospective validation., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Chronic testicular pain (CTP) is a complex pain syndrome that is widely variable in presentation and etiology. Many cases of CTP are thought to be associated with neuropathy and recent data suggest an inflammation-mediated process is more common among patients with CTP. Deficiencies in vitamin B12 and testosterone are common in chronic pain syndromes may play a role in CTP. A retrospective review of men treated for CTP by a single provider over a 2-year period was performed. Patients with serum screening of testosterone and B12 were selected. Patients with total testosterone below 300 ng/dl, free testosterone below 46 pg/ml, or B12 below 400 pg/ml were deemed deficient and offered repletion. Efficacy of treatment was measured based on patient report with a minimum follow-up of either 3 months or resolution of pain symptoms. One hundred and fifty-four (154) men with CTP were identified, with 125 assessed for testosterone and B12 levels. Of these, 95 patients (76%) were deemed deficient. Fifty-six (56) patients elected to receive B12/testosterone replacement. In patients with sufficient follow-up, 24 patients (65%) reported significant improvement of symptoms, 6 patients (16%) reported some improvement, and 7 patients (19%) reported no improvement. The prevalence of testosterone and B12 deficiencies in this study is much higher than that reported for the general population. In addition, when chemical deficiencies were corrected, greater than 80% of patients with sufficient follow-up reported some improvement in pain. This suggests that screening of B12 and testosterone should be incorporated into the assessment of patients with CTP.

Background: Chronic orchialgia is defined as testicular pain, which may be either unilateral or bilateral, lasting for more than 3 months. It disturbs a patient's daily activities and quality of life (QoL), inciting the patient to search for treatments to alleviate the pain. It is estimated that 25% of chronic orchialgia cases are idiopathic., Purpose: The purpose of this study was to investigate how effective transcutaneous electrical nerve stimulation (TENS) is in pain reduction and how it consequently affects the QoL in patients with idiopathic chronic orchialgia (ICO)., Patients and Methods: Seventy-one patients were randomly assigned to group A (study group), which included 36 patients who received TENS and analgesia, and group B (control group), which included 35 patients who received analgesia only. The outcome measures were the participants' demographic data and results of the visual analog scale (VAS) and QoL questionnaire. These outcomes were measured before and after 4 weeks of treatment and at 2-month follow-up., Results: The results showed that compared to pretreatment, there was a significant reduction in pain postintervention and at 2-month follow-up in group A ( P <0.0001 and <0.001, respectively; F =7.1) as well as a significant improvement in QoL at these time points ( P <0.0001 and <0.0001, respectively). There were no significant differences in the VAS score and QoL in group B at different time points of evaluation., Conclusion: The findings indicate that TENS is effective in reducing pain and improving patients' QoL in cases of ICO. TENS is an easy-to-use, effective, noninvasive, and simple method for ICO-associated pain control and QoL improvement., Competing Interests: Disclosure The authors report no conflicts of interest in this work.

A dilation of the pampiniform venous plexus in the scrotum above the testicle, called a varicocele, affects approximately 15% of the general male population. While the majority is asymptomatic, pain results in up to 10% of cases of varicoceles. The pain associated with varicoceles is typically mild and is described as heavy, achy, or dull-and is usually isolated to the testicle or spermatic cord. Guidelines clearly recommend varicocele repair in males with varicoceles, infertility, and an abnormal semen analysis. While chronic, severe pain is an additional indication for repair, a careful evaluation to rule out other etiologies in addition to a period of conservative management are necessary prior to surgical treatment because of the high incidental prevalence of varicoceles in the general population. Several techniques for varicocele repair have been described, including retroperitoneal, laparoscopic, inguinal, and subinguinal. Additionally, recent adjuncts to improve visualization and identification of critical structures including the operating microscope and microvascular Doppler ultrasound have improved success and complication rates. With careful patient selection, outcomes of varicocele repair with regard to pain are excellent, with over 90% of patients experiencing symptomatic relief. After failure of conservative treatments, a varicocele associated with pain should be considered for repair, and the microsurgical subinguinal approach is the gold standard surgical treatment, offering excellent outcomes while minimizing risk of complications., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Chronic idiopathic orchialgia is a urologic disease process that is as frustrating as it is common. While no consensus exists on management for otherwise-unexplained testicular pain, most providers would agree that once other treatable organic causes are ruled out, initial management should be symptom focused, and should be medical rather than surgical. This chapter presents a review of the evidence available for a variety of pharmacotherapies commonly employed in the treatment of idiopathic chronic orchialgia., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Chronic orchialgia is a challenging problem to both the practitioner and unhappy patient and may be a poorly understood manifestation of a potential variety of different discrete causes. Treatment options can be wide ranging and include conservative measures, medical therapy, in office treatments and surgical procedures. Research has primarily focused on these more concrete treatment options with little focus on the either co-morbid or causative psychological issues. By at least considering the potential psychological co-morbidities and stressors that may be associated with chronic orchialgia, physicians can better utilize a multi-modal approach to this vexing problem., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Introduction: Idiopathic testicular/groin pain can be a difficult entity for children, their families, and caregivers. The role of interdisciplinary pain management has previously been demonstrated in treating chronic orchialgia at the present pediatric pain clinic., Objective: To evaluate the role of interdisciplinary pain management in managing refractory orchialgia. It was hypothesized that children with refractory orchialgia might respond well. Interdisciplinary care was defined as that which crosses two medical disciplines such as a surgical specialty and specialist in analgesia., Subjects and Methods: Pediatric patients were identified who were: ≥ 10 years old; evaluated in the pediatric urology clinic between 2002 and 2012; were diagnosed wtih ICD code 608.9 or had the diagnosis of male genital disorder NOS. Children were included if they presented with orchialgia without an identifiable cause and failed conservative management (rest, scrotal support, Sitz bath, timed voiding, constipation avoidance) including conventional anti-nociceptive analgesics (acetaminophen, non-steroidal anti-inflammatory drugs, opioids). Patient electronic medical records were reviewed retrospectively., Results: Twenty-two children met inclusion criteria. Mean age was 13.7 years (range 10-17). Nearly half (45%) of the children had chronic medical conditions such as asthma, allergies, and obesity. Twenty-one of the 22 children were referred to the pediatric pain clinic; 15 were evaluated, and one refused treatment. All children evaluated in the pediatric pain clinic were initially offered an empiric anti-neuropathic anti-convulsant (i.e. gabapentin) and/or an anti-depressant (i.e. amitriptyline) before being offered a nerve block. Of the 14 children accepting treatment in the pediatric pain clinic, six were treated solely with an empiric anti-neuropathic anti-convulsant and/or anti-depressant; eight received medications followed by nerve block (seven ilioinguinal-iliohypogastric blocks, one spinal and ilioinguinal-iliohypogastric block) (see Fig. 1). A total of eight of the 14 children (57%) treated by the pain clinic had resolution of pain, with 50% of those treated with medications alone (three out of six children) responding (two responding to gabapentin and a tricyclic antidepressant, one to gabapentin alone); and five out of eight (63%) treated with medications and then nerve block (ilioinguinal-iliohypogastric block) responding. Of the eight children undergoing nerve block, five required more than one block. The time between each block ranged from 4 to 22.6 weeks. Response to nerve block required an average of 1.4 procedures (range 1-2); mean follow-up after nerve block was 2.4 months (range 0.1-4.8)., Discussion: Children with refractory orchialgia often have comorbidities that suggest a multidisciplinary approach would be useful for treating them. The present study found that the majority of children with refractory orchialgia treated in the pediatric pain clinic responded to management. Major limitations, however, included small cohort size and short follow-up, particularly in those children undergoing nerve block. There was also no objective assessment of pain improvement or improvement in quality of life, which could be rectified with a prospective study., Conclusion: Collaboration and early referral for interdisciplinary pain management as one of these multidisciplinary approaches may help to coordinate care and ease patient suffering., (Copyright © 2015.

Objective: A major hurdle in management of any chronic pain syndrome is understanding the population in which it occurs. We describe our pediatric population of patients with peripubertal and postpubertal chronic orchialgia., Patients and Methods: Pediatric patients ≥ 10 years of age seen between 2002 and 2012 were identified by ICD code 608.9, Male Genital Disorder NOS. Patients were included if they had orchialgia without identifiable cause lasting >3 months. Patient history, diagnostic evaluations, treatments, and outcomes were assessed., Results: Seventy-nine pediatric patients were identified. The mean age was 13.3 years (range 10-18); mean duration of orchialgia was 16.3 months (range 3-85). Thirty-three of 79 (42%) had concomitant medical conditions and/or psychiatric-behavioral issues. The mean follow-up was 7.1 months (range 0-70.4) with 41/79 (52%) having more than one office visit follow-up. Eleven patients were referred to a pediatric pain clinic; 10 out of 11 (91%) were evaluated there. Overall, 16 out of 41 (39%) had resolution of pain: nine out of 41 (22%) responding to conservative management vs seven of 10 (70%) responding to pain clinic management (3 to anti-neuropathic medications, 4 to nerve block)., Conclusion: Many pediatric patients with chronic orchialgia have co-morbidities amenable to multidisciplinary collaborative coordination of care. Referral to pediatric pain clinic can be of significant benefit., (Copyright © 2014 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.)

The incidence of varicocele in the general population is up to 15%. It is estimated that the prevalence of pain with varicoceles is around 2-10%. Till the year 2000, only two studies evaluated efficacy of varicocelectomy in painful varicoceles with conflicting results. Over the past decade many other studies have addressed this issue and reported on the treatment outcome and predictors of success. We critically appraised studies published from March 2000 to May 2013 evaluating surgical management in painful varicoceles to provide an evidence based review of effectiveness of varicocelectomy in relieving pain in patients with symptomatic painful varicoceles. The association between varicoceles and pain is not clearly established. Conservative treatment is warranted as the first line of treatment in men with painful clinical varicoceles. In carefully selected men with clinically palpable varicoceles and associated characteristic chronic dull ache, dragging or throbbing pain who do not respond to conservative therapy, varicocelectomy is warranted and is associated with approximately 80% success. However, surgical success does not always translate into resolution of pain and pain might persist even when no varicoceles are detected postoperatively.

Chronic scrotal pain can be a difficult clinical entity to treat. Many different treatment options have been proposed. We describe the case of a young boy with chronic scrotal and inguinal pain on the right side, following two orchidopexies. After many therapies had failed, we treated the dorsal root ganglia of thoracic 12, lumbar 1 and lumbar 2 with pulsed radiofrequency, finally resulting in alleviation of his pain., (Copyright © 2013 Journal of Pediatric Urology Company.
