MANAGEMENT OF CHRONIC ORCHIALGIA OF UNKNOWN ETIOLOGY

The treatment of patients with chronic unilateral or bilateral orchialgia, defined as intermittent or constant testicular pain of greater than 3 months and of unclear cause, is difficult. This pain significantly interferes with the daily activities of the patient. We have seen 12 patients with chronic orchialgia of unknown etiology and each had a normal history, physical examination and normal scrotal sonogram. Three patients were treated with nonsteroidal anti-inflammatory drugs and obtained partial pain relief. Three patients underwent spermatic cord nerve blockade using a combination of 1% lidocaine and 40 mg methylprednisolone and experienced partial pain relief. Four patients underwent inguinal orchiectomy after failing conservative management: three reported complete relief of pain, and the other partial relief. Two patients had bilateral transrectal injections of local anesthetic (5 ml bupivacaine) and methylprednisolone into the region of the pelvic plexus under transrectal ultrasound guidance. They were successfully treated with this injection technique. On the basis of our results, we recommend transrectal blockade of nerves from the pelvic plexus or inguinal orchiectomy as the procedure of choice for patients in whom medical treatment fails.     

A novel treatment of chronic orchialgia

We evaluated the effectiveness of pulsed radiofrequency (PRF) denervation of spermatic cord for the treatment of chronic orchialgia. Five patients diagnosed with chronic orchialgia were evaluated with a thorough medical and psychiatric history, physical examination, and scrotal Doppler ultrasound, urinary system x-ray film, and urine analyses. One of the patients had bilateral chronic orchialgia. All of the patients had pain for a period of at least 3 months, and multiple conservative therapies failed to alleviate the pain. The patients, who had temporary pain relief after undergoing outpatient diagnostic cord block, were determined to be candidates for PRF denervation. PRF denervation of spermatic cord was performed for 6 testicular units. Visual analog scores were noted before and after the procedure. There were no pathologic conditions that indicated chronic orchialgia in any of the patients. No complications, including testicular atrophy or hypoesthesia of the scrotal or penile skin, occurred after the procedure. Mean visual analog scores before and after the procedure were 9 and 1, respectively. None of the patients needed any analgesics after the procedure or during the follow-up period. Mean follow-up period was 20 ± 2.5 weeks. No recurrence was noted, and none of the patients needed additional therapy. This is a limited case report on the short-term use of PRF. Randomized, placebo-controlled, and long follow-up period studies are needed to better assess the efficacy of this procedure for chronic orchalgia.     

Microsurgical subinguinal cremaster muscle release for chronic orchialgia secondary to hyperactive cremaster muscle reflex in adults

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.     

Chronic orchialgia in the pain prone patient: the clinical perspective

Chronic pain syndromes are well known to the medical community. The incidence of chronic pain syndromes and cost of evaluating these patients are rapidly increasing. Chronic testicular pain is a fairly common manifestation of a chronic pain syndrome. Retrospectively, we reviewed the records of 48 patients with chronic testicular or scrotal pain (greater than 6 months) evaluated at our institution during the last 7 years. These patients had multiple diagnostic and interventional procedures with few positive findings. There was little improvement in these patients after multiple surgical procedures. Based on the paucity of objective clinical findings a carefully directed diagnostic evaluation for orchialgia is outlined. The treatment of these patients is best managed by a multidisciplinary approach involving the urologist and a pain clinic environment. We believe that extensive diagnostic testing is not indicated in the absence of clinical findings and may serve to worsen the condition or lead to iatrogenic injury. Surgical intervention should be limited to cases when a clear indication is present.     

Urethral and scrotal pain syndromes

Painful diseases of the pelvis are not rare. Urethral and scrotal pains are part of the chronic pelvic pain syndromes along with chronic prostatitis and painful bladder syndrome/interstitial cystitis. The objective of this review is to update the current knowledge about epidimiology, etiology, diagnosis and best treatment for patients with urethral and scrotal pain syndromes. Epidemiological data for both syndromes are scant. We lack of uniform definition or readily available diagnostic marker and aetiology remains unclear. The pain could be a neuropathic without a specific stimulus or disproportionate to the stimulus intensity. Regarding diagnosis, there is no evidence to qualify or quantify the symptoms to include or exclude patients. Nevertheless, it is very important to know functional neuroanatomy in the evaluation of these patients. Treatment always should be primary conservatively. Surgery should be avoided if possible. As no specific treatment is available, decrease the pain is the main objective, therefore urologist should know how to manage analgesics, antidepressant and anticonvulsants.     

Clinical phenotyping in chronic prostatitis/chronic pelvic pain syndrome and interstitial cystitis: a management strategy for urologic chronic pelvic pain syndromes

The urologic chronic pain conditions such as chronic prostatitis/chronic pelvic pain syndrome and interstitial cystitis are syndromes whose evaluation and management are controversial. Part of the difficulty in diagnosis and therapy is the heterogeneity of etiologies and symptoms. We propose a six-domain phenotype, which can classify these patients clinically and can direct the selection of therapy in the most evidence based multimodal manner. The domains are urinary, psychosocial, organ specific, infection, neurologic and tenderness of skeletal muscles. This system is flexible and responsive to new biomarkers and therapies as their utility and efficacy are proven.     

Alternative Approaches to the Management of Prostatitis: Biofeedback,Progressive Relaxation and the Concept of Functional Somatic Syndromes

Specific mechanisms underlying chronic pelvic pain syndrome have yet to be identified. However, the disorder has features common to other chronic pain syndromes, such as fibromyalgia and chronic pelvic pain in women. Like other chronic pain patients, men presenting with chronic prostatitis may meet diagnostic criteria for other functional pain syndromes as well as affective disorders, which should be screened for. Finally, as with other chronic pain conditions, chronic nonbacterial prostatitis patients respond very well to non-specific modalities that act to reduce stress and/or muscle tension, including progressive relaxation and biofeedback.     

Chronic orchialgia: Consider gabapentin or nortriptyline before considering surgery

OBJECTIVE: To establish if there is a role for gabapentin or nortriptyline in the treatment of chronic orchialgia. METHODS: Twenty-six consecutive patients with chronic orchialgia were seen in the chronic pain clinic by a multidisciplinary team. A pain questionnaire was completed prior to commencing either gabapentin or nortriptyline. They were reviewed at 3 months and a repeat questionnaire completed. A 50% improvement in pain was considered successful. RESULTS: Complete data was available for 19 patients. Overall, 61.5% of patients commenced on gabapentin and 66.6% of patients commenced on nortriptyline had a greater than 50% improvement in pain. Patients with post-vasectomy testicular pain were considered as a subgroup. None of these patients had a greater than 50% improvement in pain. However, 80% of patients in the subgroup with idiopathic chronic orchialgia had a greater than 50% improvement in pain. CONCLUSION: Although this is a small study, it appears that gabapentin and nortriptyline are effective in the treatment of idiopathic chronic orchialgia but not post-vasectomy pain.     

Testicular fixation in adult retractile testis: technical notes

A variety of techniques for scrotal orchiopexy have been described in the literature, including those without suture fixation, such as the scrotal pouch. We perform a simple modified technique for bilateral testicular fixation in patients with bilateral and/or unilateral adult retractile testis and with symptoms characterised by chronic orchialgia due to testicular hypermobility or repeated funicular subtorsion.     

Schmerztherapeutische Optionen beim urologischen chronischen Beckenbodenschmerzsyndrom (UCPPS)

Approximately 10% of the population suffers from chronic pain in the urogenital region. The multidimensionality of this chronic pain syndrome must be taken into consideration. The cause of urologic chronic pelvic pain syndrome (UCPPS) is mostly unclear. Treatment of these patients should be carried out in specialized institutions.     

Chronic testicular pain: an overview

Chronic testicular pain (orchialgia, orchidynia or chronic scrotal pain) is common and well recognized but its pathophysiology is poorly understood. Currently treatment is largely empirical. This article aims to present an overview of its prevalence, possible aetiology and the available treatment options. The contribution of psychological factors is unclear, although some of these patients undoubtedly are depressed. Post vasectomy chronic testicular pain may be due to functional obstruction of the vas, or to spermatic granuloma. The surgical technique used may be relevant and the application of intraoperative local anaesthetic may have a role in reducing the risk. The importance of the sympathetic nervous system and the role of a possible alteration of the adrenergic receptors of the vas deferens in patients with chronic testicular pain are discussed. For patients failing to respond to conservative treatment, microsurgical denervation of the spermatic cord, epididymectomy and vasovasostomy have all shown a degree of relief. Unfortunately a small number of patients fail to respond to both conservative and more invasive treatment methods and for them the only available therapeutic option is inguinal orchiectomy.     

Analysis and management of chronic testicular pain

A total of 45 patients was seen in consultation between May 1980 and April 1989 for chronic unilateral or bilateral orchialgia, defined as intermittent or constant testicular pain 3 months or longer in duration that significantly interferes with the daily activities of the patient so as to prompt him to seek medical attention. We analyzed 34 patients available for followup in terms of socioeconomic parameters, etiology and duration of pain, associated urological symptomatology, specific treatment and results of therapy. Of the patients 31 underwent surgical treatment after failing medical management (24 orchiectomies, 10 epididymectomies, 5 orchiopexies and 1 hydrocelectomy). Of 10 patients who underwent epididymectomy 9 underwent subsequent orchiectomy as definitive treatment. Of 15 patients who underwent inguinal orchiectomy 11 (73%) reported complete relief of pain, while 4 had partial relief. Of the 9 patients who underwent scrotal orchiectomy 5 (55%) reported complete relief of pain, 3 had partial relief and 1 denied improvement. On the basis of these results we recommend inguinal orchiectomy as the procedure of choice for the management of chronic testicular pain when conservative measures are unsuccessful.     

EAU guidelines on chronic pelvic pain

OBJECTIVES: On behalf of the European Association of Urology (EAU) guidelines for diagnosis, therapy and follow-up of chronic pelvic pain patients were established. METHOD: Guidelines were compiled by a working group and based on current literature following a systematic review using MEDLINE. References were weighted by the panel of experts. RESULTS: The full text of the guidelines is available through the EAU Central Office and the EAU website (www.uroweb.org). This article is a short version of this text and summarises the main conclusions from the guidelines on management of chronic pelvic pain. CONCLUSION: A guidelines text is presented including chapters on prostate pain and bladder pain syndromes, urethral pain, scrotal pain, pelvic pain in gynaecological practice, role of the pelvic floor and pudendal nerve, general treatment of chronic pelvic pain and neuromodulation. These guidelines have been drawn up to provide support in the management of the large and difficult group of patients suffering from chronic pelvic pain.     

Bacteria in the chronic prostatitis-chronic pelvic pain syndrome: molecular approaches to critical research questions

PURPOSE: There is a pressing need to determine the causes and consequences of, and optimal therapy for the chronic prostatitis-chronic pelvic pain syndrome. MATERIALS AND METHODS: New data suggest that bacterial infection may be critical in some patients. We examined the rationale for and technical approaches to hypothesis driven studies of bacteria in the chronic prostatitis-chronic pelvic pain syndrome. RESULTS: The first hypothesis was that patients with the chronic prostatitis-chronic pelvic pain syndrome have prostatic bacteria that distinguish them from controls. In pilot studies patients with inflamed expressed prostatic secretions were more likely to have bacterial DNAs, that is 16S ribosomal DNAs. Current goals are to clone, sequence and compare ribosomal DNAs from patients and controls to determine which bacteria are most specific to the chronic prostatitis-chronic pelvic pain syndrome and which should be targeted in clinical trials. The second hypothesis was that bacterial viability correlates with the severity of the chronic prostatitis-chronic pelvic pain syndrome. Quantitative assays for bacterial elongation factor messenger RNA (tufA messenger RNA) provide tools to correlate bacterial viability with patient characteristics, will provide insights into the potential value of antimicrobial therapy and identify characteristics that distinguish patients most likely to respond. The third hypothesis was that patients with prostatic bacteria have similar bacteria in expressed prostatic secretions or on seminal fluid analysis and, furthermore, these bacteria differ from bacteria in controls. These studies would determine whether expressed prostatic secretions or seminal fluid analysis can be used to identify prostatic bacteria and may result in clinical methods for noninvasive diagnosis of prostatic infection. CONCLUSIONS: These studies should provide important insights into the causes of the chronic prostatitis-chronic pelvic pain syndrome and may elucidate optimal clinical evaluation and treatment in patients.     

Predictors of patient response to antibiotic therapy for the chronic prostatitis/chronic pelvic pain syndrome: a prospective multicenter clinical trial

PURPOSE: To our knowledge antibiotics are the most popular choice of therapy for all categories of the chronic prostatitis/chronic pelvic pain syndrome. We determine if culture, leukocyte and/or antibody status of prostate specific specimens predicts patient response to antibiotic therapy. MATERIALS AND METHODS: Patients clinically diagnosed with the chronic prostatitis/chronic pelvic pain syndrome according to the National Institutes of Health (NIH) definition had a lower urinary tract evaluation that included standard microscopy and culture of prostate specific specimens, and determination of the ratio of voided bladder 3 and voided bladder 2 antibody levels against a panel of identified prostate pathogens (enzyme linked immunosorbent assay methodology). Symptom evaluation consisted of the NIH chronic prostatitis symptom index (derived) pain scale 0 to 21, symptom severity index scale 0 to 100, symptom frequency questionnaire scale 0 to 50 and quality of life scale 0 to 6. Patients were stratified according to microscopy, culture and immune status, were treated with 12 weeks of ofloxacin, and were assessed at 4, 12 and 24 weeks with symptom scores as well as global assessments. RESULTS: Based on leukocyte and culture results, 102 evaluable patients were stratified into categories II (14%), IIIA (48%) and IIIB (38%) of the chronic prostatitis/chronic pelvic pain syndrome. Of the cases 23% were categorized as antibody positive and 77% as antibody negative. Average age was 42 +/- 10 years and 92% of patients were white. Of the patients 57% believed that they had moderate to marked improvement. All categories of the chronic prostatitis/chronic pelvic pain syndrome and patients in whom antibody was positive or negative had significant improvement in the NIH chronic prostatitis symptom index, symptom severity index, symptom frequency questionnaire and quality of life scores compared with baseline (p <0.001). There was no significant difference in patient response to the stratification based on culture, leukocyte, that is categories II, IIIA and IIIB had same beneficial response, or antibody status. CONCLUSIONS: Culture, leukocyte and antibody status of prostate specific specimens does not predict antibiotic response in patients with the chronic prostatitis/chronic pelvic pain syndrome. The perceived beneficial effect of antibiotics needs to be evaluated in a randomized placebo controlled trial.     

Gonadoblastoma in an anatomically normal man: a case report and literature review

Gonadoblastoma, a rare gonadal neoplasm, presents most frequently in phenotypic female or phenotypically male patients with dysgenetic gonads or undescended testes. To date, only 2 cases of gonadoblastoma have been reported in anatomically normal male patients with scrotal testes. Both of these patients presented with testicular masses and germ cell tumors. We report a case of a genotypically and phenotypically normal, fertile man with descended testes who on evaluation for chronic orchialgia had a gonadoblastoma unaccompanied by a germ cell neoplasm. The tumor was nonpalpable and was initially discovered on scrotal ultrasound.     

Role of US in acute scrotal pain

Background

The acute scrotum is a common emergency department (ED) presentation and can be defined as any condition of the scrotum or intrascrotal contents requiring emergent medical or surgical intervention. Although rarely fatal, acute scrotal pathology can result in testicle infarction and necrosis, testicular atrophy, infertility, and significant morbidity.

Methods

Scrotal US is best performed with a linear 7.5- to 12-MHz transducer. In addition to imaging in the longitudinal and transverse planes, it is helpful to obtain simultaneous images of both testes for comparison. Color Doppler is used to evaluate for abnormalities of flow and to differentiate vascular from nonvascular lesions. Attention to appropriate color Doppler settings to optimize detection of slow flow is critical.

Results

The evaluation of acute scrotal pain can be challenging for the clinician initially examining and triaging the patient. Acute scrotal conditions due to traumatic, infectious, vascular, or neoplastic etiologies can all present with pain as the initial complaint. Additionally, the laboratory and physical examination findings in such conditions may overlap; this, coupled with potential patient guarding and lack of collaboration, may result in a limited, non-specific physical examination. Therefore, scrotal ultrasound has emerged to play a central role in the evaluation of the patient presenting with acute scrotal pain.

Conclusions

In conclusion, we are firmly convinced that a scrotal ultrasound should always be performed in the presence of acute scrotal pain. Moreover, urologist should be able to perform a scrotal ultrasound but, if imaging does not supply a clear diagnosis, surgical exploration is still mandatory.     

Gastroenterological causes of pelvic pain

 Chronic pelvic pain is a common condition, which accounts for up to 10% of gynecological consultations and for over a third of diagnostic laparoscopies. In addition to gynecological etiologies for the pelvic pain, the physician must also consider gastroenterological, urological, and neurological disease as a possible basis for the pain. This article discusses the major gastroenterological causes of pelvic pain.     

Chronic pelvic pain: An imaging approach

Chronic pelvic pain is defined as disabling pain of at least six months duration. Chronic pelvic pain has often multiple causative factors. Careful analysis of clinical history and detailed clinical examination must be carried out to guide further imaging investigations. Endometriosis is a common cause of chronic pelvic pain, although there is no correlation between the severity of lesions and pain intensity. Pelvic ultrasonography should be the first line imaging examination to search for causative conditions that include endometriosis, adenomyosis, pelvic varices and chronic infection. Magnetic resonance imaging (MRI) is useful for making the positive diagnosis and assessing the spread of endometriosis. MRI is more accurate than ultrasonography for the diagnosis of tubo-ovarian abscess when an adnexal mass is identified. Duplex and color Doppler ultrasonography as well as MR angiography are the best imaging technique for the diagnosis of pelvic congestion syndrome. In patients with pudendal neuralgia, cross-sectional imaging help exclude nerve compression.
