Case Reports in Urology最新文献

Plasmacytoid urothelial carcinoma (PUC) of the bladder is a rare variant of invasive urothelial carcinoma (UC) with aggressive behavior. Despite its prognosis being poorer than that of conventional UC, a median overall survival of approximately 2 years is ensured when it is treated with radical cystectomy (RC), and few patients die within a few months of RC. In this paper, we report the case of a patient with PUC who developed widespread bone metastasis only 6 weeks after RC, which resulted in death within 2 months postoperatively.

Background: Large urinary bladder stones are not common and even less common in females. We report a case of large bladder stone presented with acute retention of urine in a female patient. Case Report. A 62-year-old female presented in emergency department with retention of urine for 12 hours with history of recurrent UTIs for last 1 year. She was also complaining of mild dull lower abdominal pain for last 6 months. She had no history of incontinence of urine and fever. On physical examination, hard mass was palpable on suprapubic region on palpation of abdomen. Urine culture shows Escherichia coli for which antibiotics was given. An X-ray kidney ureter bladder showed a radio-opacity in the pelvic region measuring 9 × 8 cm in size. Ultrasonography revealed bilateral mild hydronephrosis with a large bladder stone. Open cystolithotomy was performed, and the stone was taken out. Stone biochemical analysis showed predominantly urate crystals. Patient had uneventful postoperative course, and she was discharged on 4^th postoperative day and was followed up for 1 months after operation.

Conclusions: Large urinary bladder stones are not common and even less common in females. Clinician should have think regarding large bladder stone as a cause of recurrent lower urinary tract symptoms like dysuria and should assess renal function for proper treatment. Open cystolithotomy is choice of operation in large bladder stone.

Perineal carcinoma of unknown origin is a rare and aggressive disease, so an early diagnosis and adequate treatment are essential to prevent its progression. We report the first series of cases of perineal carcinoma of unknown origin: (I) a 62-year-old male patient being followed up for a urethral stricture treated with periodic dilations with subsequent development of perineal abscesses and perineal carcinoma; (II) a 67-year-old male patient who consults for urinary discomfort associated with a perineal abscess. Recurrence of the abscess in the first month revealed the presence of an underlying perineal carcinoma; (III) a 78-year-old male patient that underwent urethroplasty with graft with subsequent regimen of periodical dilations. Recurrent formation of perianal abscesses revealed the presence of an underlying perineal carcinoma; and (IV) a 78-year-old male patient with history of in situ penile carcinoma treated by glans resurfacing. He consulted for penile pain, and imaging tests revealed a perineal abscess adjacent to the left corpus cavernosum. The core needle biopsy revealed a squamous cell carcinoma. Penile exploration and negative glans biopsy ruled out possible recurrence of penile carcinoma. The form of presentation of the disease has been very similar in all patients, demonstrating the presence of perineal abscess in all cases. Two patients had inguinal lymph node disease at diagnosis. All patients were treated by surgery, and three of them required adjuvant systemic treatment. Surgery combined with systemic treatment is probably the best option if the patient's conditions allow it.

Introduction: A metastatic testicular tumor is uncommon. We report here a case of testicular metastasis associated with recurrent colorectal cancer. Case Presentation. A 75-year-old male was presented with right scrotum pain one year after undergoing a right hemicolectomy combined with resection of the small intestine and omentum for ascending colon cancer (pT4N0M0). Magnetic resonance imaging of the pelvis showed a 7.3 × 5.4 × 4.5 cm mass consisting of a cystic solid tumor. A right inguinal orchiectomy was performed and right testicular pain improved after surgery. Pathology results showed that the tumor was a metastatic adenocarcinoma. The patient subsequently died two months later due to progression of the colon cancer.

Conclusion: Although colorectal cancer metastasis to the testis is very uncommon, it should be kept in mind in clinical situations, especially for older males with a testicular mass or discomfort.

Penile hair tourniquet syndrome (PHTS) is an unusual phenomenon. A physician should have a high index of suspicion when a circumcised child presents with glans swelling and inflammation. It must be considered a surgical emergency, as early diagnosis and treatment can prevent complications (e.g., urethra-cutaneous fistula, complete urethral transection, penile gangrene, and penile amputation). We report a case of two-year-old boy to highlight the importance of early diagnosis and prompt treatment.

Epididymo-orchitis is an infection of the epididymis and testis, one of the most common urogenital infections. It can be seen at any age. It is caused by sexually transmitted microorganisms and nonsexual transmitted pathogens. Viruses such as mumps and cytomegalovirus can also cause epididymo-orchitis. During the COVID-19 pandemic, in case of abnormal clinical manifestations of COVID infection and inadequate therapeutic response to the routine therapies, this disease with unusual manifestations should be considered. The case introduced in this paper is a 55-year-old man referred to a urology clinic with typical clinical presentations of epididymo-orchitis. Diagnosis by color Doppler examination and ultrasound also confirmed epididymo-orchitis. The patient underwent appropriate and routine treatment for epididymo-orchitis. Because of the lack of adequate clinical response and the continuation of fever and the development of scrotal lesions and the results of the control ultrasound, which suggested rupture of the tunica albuginea capsule, he underwent surgical exploration and subsequent orchiectomy. Due to the unconventional conditions and the usual culture and pathology, COVID-19 PCR was also performed on the tissues. The PCR showed tissue infection with COVID-19. The patient's clinical condition improved with an orchiectomy, the fever stopped, and he was discharged in a good general condition. It should be noted that before referral to the urology clinic and during hospitalization, evaluation, and treatment, the patient had no evidence in favor of respiratory tract infection with the coronavirus.

Prostate adenosquamous carcinoma (pASC) is a rare form of prostate cancer accounting for <1% of all cases. It is generally considered an aggressive variant often presenting with significant symptom burden and/or metastatic disease. Given its rarity, optimal management of this cancer is unknown. We present a case of a patient with pASC treated with radiotherapy and chemotherapy with excellent symptomatic improvement and local control.

A 70-year-old male was diagnosed with urothelial carcinoma of the upper renal pelvis on the left side of the horseshoe kidney. Preoperative thin-slice contrast-enhanced CT with three-dimensional reconstruction of the images revealed that two arteries arising from the aorta supplied the left moiety of the horseshoe kidney. He underwent laparoscopic transperitoneal nephroureterectomy with heminephrectomy on the left side of the horseshoe kidney visualized by indocyanine green fluorescence system. The histopathological findings of the renal pelvic tumor revealed invasive urothelial carcinoma with squamous differentiation, high grade, and pT3.

Renal cell carcinoma (RCC) is considered to be the deadliest urologic cancer with high rates of metastasis and recurrence after nephrectomy. RCC can metastasize to nearly any organ but most commonly metastasizes to the liver, lung, brain, and bone. To date, there are only about 40 reported cases of RCC with solitary bladder metastasis. The following report contributes to this limited data set of patients with RCC who develop solitary metastasis to the bladder. A 69-year-old male presented with occasional gross hematuria and was found to have a left renal mass infiltrating the collecting system. Ureteroscopic biopsy revealed clear cell RCC, and the patient subsequently underwent radical left nephrectomy. Eight months after nephrectomy, the patient presented to the clinic with gross hematuria. In-office cystoscopy demonstrated a nodular lesion in the bladder arising from the left ureteral orifice. The patient underwent transurethral resection of the bladder mass and pathology demonstrated clear cell RCC. Subsequent imaging showed no evidence of metastatic disease. Five months after transurethral resection, the patient was found to have a left distal ureteral mass and underwent left ureterectomy with partial cystectomy. Pathology again demonstrated clear cell RCC. RCC with solitary metastasis to the bladder is rare, and there are no targeted guideline recommendations for management. Per standard of care, patients with painless hematuria and risk factors for malignancy should undergo cystoscopy. In patients with a history of RCC, metastasis to the bladder should be considered in the differential diagnosis. Patients with metastatic RCC to the bladder should undergo a thorough work-up for additional sites of metastasis. In patients with RCC who develop solitary bladder metastasis amenable to resection following nephrectomy, there is a lack of evidence to guide therapy and a multidisciplinary discussion is warranted. However, if the tumor is amenable to resection, metastasectomy is a reasonable therapeutic approach and offers the patient an improved quality of life and an opportunity for remission.

Melanin accumulation within the bladder urothelium and/or macrophages in the lamina propria (melanosis of the bladder) is a very rare phenomenon of unknown pathogenesis. Its rarity argues for a complex, likely multifactorial, causation. We describe bladder melanosis developing after Botox therapy in an elderly woman with a history of overactive bladder, treated grade 2 uterovaginal prolapse, and episodes of urinary tract infection and speculate that one factor (probably of many) in its pathogenesis may be a derangement of local neurourothelial interactions.
