Surgical excision of acquired urethral diverticulum and single-stage urethroplasty for a 32-year-old male. Case report and literature review.

INTRODUCTION: Urethral diverticulum (UD) is a saccular dilatation of the urethral wall, continuous with the true urethral lumen. It is categorized etiologically into congenital and acquired. The etiology of an acquired urethral diverticulum is thought to be secondary to trauma. The gold standard imaging modalities for diagnosis of UD are retrograde urethrogram (RGU) and micturating cystourethrogram (MCU). Management options include: nonoperative treatment, minimally invasive and open surgeries. Open surgeries comprise a primary anastomosis or, Substitution urethroplasty after UD excision, with the aim of excising the diverticulum, reestablishing the continuity of the urethra, and prevent urethrocutaneous fistula formation. We present a case of urethral diverticulum and bulbar urethral stricture successfully managed by surgical excision of UD and substitution urethroplasty. CASE PRESENTATION: We report a case of a 32-year-old man who had lower urinary tract symptoms following a traumatic urethral catheterization. Investigations done in a peripheral hospital revealed a short, bulbar urethral stricture and direct visual internal urethrotomy (DVIU) was done. Later he presented to us with urine retention, whereupon emergency suprapubic cystostomy was performed. After serial investigations, urethral diverticulectomy followed by single stage urethroplasty with ventral onlay buccal mucosa graft was done. He was followed for 12 months with good surgical outcome. DISCUSSION: The development of Acquired UD has been attributed to several possible factors: pelvic fractures, urethral strictures, straddle injuries, long-term urethral catheterization, endoscopic direct injuries, lower urinary tract infections, and urethral surgeries. Depending on the presentation and investigation findings, management of UD is planned. Conservative management is possible for uncomplicated asymptomatic UD if the patient consents to follow-up. Surgery to remove the diverticulum and urethral reconstruction are required for complicated symptomatic UD; these procedures vary from patient to patient and are individualized. CONCLUSION: It is important to base the choice to do surgery on the clinical presentation. Whether a concurrent urethral stricture is present is a critical factor in deciding on the best course of surgical treatment. In our case we opted to perform a substitution urethroplasty with ventral onlay buccal mucosa graft as our patient had a long bulbar urethral stricture proximal to the diverticulum.

Successful surgical excision of the accessory urethra in a 13-year-old boy with Effmann Type IIA-2 urethral duplication. Case report and literature review.

INTRODUCTION AND CLINICAL IMPORTANCE: Urethral duplication is a congenital anomaly characterized by the partial or full development of an auxiliary urethra as a second urethral channel varying in extent and location. The course of treatment for urethral duplication should be individualized for each patient based on the type of anomaly and the existence of symptoms. In most cases, if the ventral orthotopic urethra is normal, excision of the dorsal auxiliary urethra is almost always curative. CASE PRESENTATION: We report a case of a 13-year-old boy who presented with recurrent urinary tract infection, occasionally having drops of urine at an external pin hole meatal opening on the dorsum of the penile shaft. Several investigations were performed to confirm the presence of the dorsal accessory urethra. The patient underwent complete excision of the accessory urethra, and 12 weeks post-surgery the patient was completely asymptomatic. DISCUSSION: Urethral duplications are rare anomalies. These anomalies have been classified in various ways in the literature, including sagittal and lateral duplications, dorsal and ventral duplications. The sagittal plane is where the majority of urethral duplications occur. Based on the anatomic variation, clinical presentation and severity of the anomaly, urethral duplication treatment should be customized for each patient. An asymptomatic child may require no specific treatment. Total surgical excision of the dorsal accessory urethra appears to offer the best curative solution. CONCLUSION: Excision of the dorsal accessory urethra is usually curative when the ventral orthotopic urethra is normal. Thorough investigation before surgery is mandatory to determine the type of urethral duplication. The most common diagnostic procedures for urethral duplications include cystoscopy, KUB ultrasonography, and micturating cystourethrography. These procedures can help plan surgery, prevent complications such as neurovascular bundle injuries and urine incontinence, and improve patient self-esteem and quality of life.

Advanced prostate cancer with brain metastasis presenting with isolated severe headache without urinary symptoms.: Case report and literature review.

INTRODUCTION AND CLINICAL IMPORTANCE: Brain metastases from prostate cancer are uncommon, occurring in fewer than 1 % of cases of metastatic prostate cancer. Brain metastasis can cause cerebral edema, neurologic symptoms, and may be misdiagnosed as primary brain tumors on imaging if thorough investigations are not done. It is difficult to identify and diagnose brain metastasis from prostate cancer since the intracranial metastatic process and presentation are poorly understood and limited to case studies. Most patients with brain metastases from prostate cancer exhibit a variety of metastatic symptoms; however, this patient's presentation was defined by only isolated intense headache. Our goal is to draw attention to the uncommon instance of brain metastases from prostate cancer in addition to reviewing the literature on the advances in treatment for prostatic cancer with metastasis to the brain. CASE PRESENTATION: We report the case of a 67-year-old male with metastatic prostate adenocarcinoma into the brain, presenting with isolated severe headache with no prostate cancer symptoms. Following extensive radiologic examination, metastatic deposits were detected in the left side of the brain with multiple intracerebral and cerebellar vermis lesions. Multiplanar T2 weighted abdominal pelvic MRI visualized the primary lesion in the prostate which was confirmed by histology. After a month following surgical castration, the patient reported resolved headache and resumed his daily activities. The patient's serum PSA decreased from 7.8 ng/ml to 0.3 ng/ml during a 12-months follow-up with no neurological symptoms. CLINICAL DISCUSSION: Prostate cancer rarely causes brain metastases, and the percentage of all brain metastases that originate from prostate cancer is seldom updated. It can be difficult to distinguish between primary brain lesions and metastatic brain prostate cancer, particularly when there is just one lesion present. Despite the recently developed diagnostic approaches, symptomatic patients exhibit a variety of clinical manifestations that vary depending on the location of the metastatic focus. These manifestations include headache, seizures, and focal neurological deficits, in addition to some common non-focal manifestations like confusion and memory deficits. Our patient had a PSA of 7.8 ng/ml at the beginning and the DRE results were normal, clinically prostate cancer was not thought to be the main cause of brain metastasis. Abdominal pelvic MRI was performed to investigate the primary lesion and confirmed the presence of prostate cancer with extra prostatic extensions. Adenocarcinoma prostate cancer was found to be the main cause when histopathology was done. CONCLUSION: This report reviews the literature on brain metastases from prostate cancer and points out that while very rare, brain metastases from prostatic cancer do occur and should not be overlooked, particularly in light of the recent advancements in prostatic cancer therapies that may extend the patient's survival. Gadolinium-enhanced MRI is necessary to confirm or rule out brain metastases if it is suspected, as well as to monitor prostate cancer patients.

Isolated testicular tuberculosis mimicking testicular malignancy in a 45-year-old male treated at a tertiary hospital. Case report and literature review.

INTRODUCTION AND IMPORTANCE: Tuberculosis is prevalent in African countries especially in sub-Saharan Africa where HIV/AIDS is common. While Testicular tuberculosis is uncommon in the young as well as the elderly, pulmonary tuberculosis is commonly observed in these populations. History, physical examination, scrotal ultrasonography, and fine needle biopsy are important in diagnosis of suspected cases of testicular tuberculosis. Anti-TB therapy is the mainstay of treatment to ensure complete resolution of the lesion. However, in a few cases, orchidectomy is required for both diagnosis and treatment. When treating testicular tuberculosis, it is crucial to do a thorough assessment and investigations to exclude testicular malignancy because tuberculosis can present similarly to a testicular tumor. CASE PRESENTATION: We report a rare case of right sided isolated testicular tuberculosis in a 45-year-old male who came with right sided testicular pain and swelling. Blood workups and testicular tumor markers were all normal, scrotal ultrasound reported right heterogenous testicular mass with avascular areas of necrosis and septated fluid collections in the tunica vaginalis with features suggestive of testicular tumor. Right orchiectomy through inguinal approach was done, findings included testicular mass with pus pockets and caseous necrosis occupying the whole testis. Specimen was sent for histopathology which revealed chronic granulomatous inflammation, most likely tuberculosis, and ZN stain confirmed the diagnosis of testicular tuberculosis. In accordance with national TB guidelines, the patient had anti-TB medication for six months, and after 12-months serial follow-up, the patient had completely recovered. CLINICAL DISCUSSION: Genitourinary tuberculosis is the second most common form of extrapulmonary TB after lymph node tuberculosis. 0.5 % of genitourinary TB involves the testes; On the other hand, isolated testicular TB as presented in our patient, is extremely uncommon, thus may mimic other testicular conditions including testicular tumor, so the diagnosis is challenging. It is important to accurately diagnose testicular TB and differentiate it from other scrotal pathologies especially testicular malignancy as the management is totally different. Testicular tuberculosis is diagnosed by tissue Cytology using FNAC or after an orchidectomy. It requires early, regular, full course combined anti-tuberculosis treatment. The drug treatment method uses three to four anti-tuberculosis drugs for 6-9 months. Surgical treatment is necessary if there is no response to drug treatment or in cases of abscess formation. CONCLUSION: Testicular TB is a curable disease, but its diagnosis remains challenging. It is often missed owing to its non- specific symptoms. Thus, testicular TB should be suspected in patients with a notion of contagion or history of tuberculosis. Some of the radiological features are highly suggestive of testicular TB. FNAB could prevent unnecessary orchidectomy. In our case, the presentation was typically mimicking a testicular cancer and the patient underwent trans inguinal orchiectomy, and histology and ZN stain confirmed the diagnosis followed by subsequent six-month anti TB therapy.

A rare case report of ectopic-adrenal paraganglioma with inferior vena cava infiltration. Case report and literature review.

INTRODUCTION AND IMPORTANCE: Phaeochromocytomas are neuroendocrine neoplasms arising from chromaffin cells of the adrenal medulla and are known as intra-adrenal paragangliomas. On the contrary, paragangliomas are non-epithelial neuroendocrine neoplasms that produce other peptide hormones such as norepinephrine, epinephrine, and dopamine. In a setting with limited resources, such a condition may result in inaccurate diagnosis and treatment, which may lose a patient life if left untreated. In addition, PPGLs present a surgical challenge to many surgeons who are not thoroughly prepared. CASE PRESENTATION: We describe a case of extra-adrenal paraganglioma in a 27-year-old female who presented with symptoms of heartbeat awareness for almost a year and abdominal swelling for three months. Physical examination revealed a palpable mass around the umbilicus. Abdominal pelvic CT scan revealed a well-circumscribed mass in the central retroperitoneum displacing the IVC laterally and abdominal aorta medially with no invasion of surrounding structures. Results for pheochromocytoma workup showed elevated levels of 24-h urine Vanillylmandelic acid (VMA), and 24-h metanephrine excretion. Laparotomy through extended midline incision was done with successful excision of the tumor. The blood pressure, which was initially high normalized after surgery. DISCUSSION: The diagnosis of a malignant EAP is commonly made based on recurrence and the development of metastasis to lymph nodes or to other organs. Our patient presented with similar symptoms as pheochromocytoma. Compared to the commonly stated 10 % risk for pheochromocytomas, people with EAPs have been observed to have a 20 % to 50 % incidence of malignancy. EAPs account for at least 15 % of adult and 30 % of pediatric pheochromocytomas and are frequently found in the Zuckerkandl organ. Pheochromocytoma symptoms may manifest asymptomatically in patients with EAPs, or they may occur because of compression of nearby tissues. Surgical excision of the tumor is always the best option in managing EAP. CONCLUSION: Extra-adrenal paragangliomas can be successfully managed surgically, provided there is a multidisciplinary team, and the tumor location is well recognized and can reduce the chance of tumor metastasis.

"A successful reconstruction of remnants of corporal bodies and penile urethra after Total Glans Penis amputation following surgical circumcision in a 5-year-old boy". A case report and literature review.

INTRODUCTION AND IMPORTANCE: Circumcision is the most common surgical procedure done in boys. Its complication varies from minor to severe. In most of African countries circumcision is often performed by traditional circumcisers. The management of penile glans amputation depends on the duration before presentation with auto-transplantation being the favorable management in acute phase of presentation. The amputation of the glans is a serious complication of circumcision because it can derange the urinary and sexual functions of a patient and may lead into psychological instability and low self-esteem. CASE PRESENTATION: We report a case of total glansectomy in a 5-year old boy who presented 12 months after surgical circumcision which was done by inexperienced medical personnel at his house. Patient presented with a pinhole urethra opening, missing glans, buried phallus with remnants of corporal bodies. Penile exploration was done, with successful significant phallus stump of about 5 cm, phallus reconstruction and meatoplasty was achieved. Partial Skin thickness grafting of the phallus stump was performed. At six- month follow up, the patient had both satisfactory cosmetic and functional outcomes. CLINICAL DISCUSSION: Total glansectomy is a rare surgical emergency with auto transplantation being the best option in acute management however successful outcome for a delayed glansectomy depends on proficient surgical penile exploration and comprehensive post operative care. Based on the clinical presentation, the goals of management for our patient were to achieve a largely patent urethral opening in the long term and to prevent further urethral meatal stenosis as well as achieving adequate phallus stump for sexual function. CONCLUSION: The amputation of the glans is a serious complication of circumcision because it can derange the urinary and sexual functions of a patient if neglected. Findings on this case report highlight the importance of raising awareness among traditional health care workers to prevent urinary and sexual function disabilities. Prevention of penile amputation can be prevented by providing proper training for circumcisers and providing public education for hospital circumcision.
