Solitary Brain Metastasis Detected 1 Year After Robot-Assisted Laparoscopic Radical Nephrectomy: A Case Report

Brain metastases are not rare in patients with renal cell carcinoma. However, there have been few reports of isolated brain metastases. In patients with localized renal masses, urologists tend to evaluate only the chest and abdomen region. We report the case of a 65-year-old patient who presented with sudden left-sided weakness. He underwent brain surgery after a mass was found on brain imaging. Histopathology analysis revealed a single brain metastasis that occurred 15 months after robot-assisted laparoscopic radical nephrectomy for renal cell carcinoma. Although the patient had been evaluated for localized kidney cancer in preoperative staging, he had not complained of any neurological symptoms before or after radical nephrectomy. Therefore, we had not perceived a need for brain evaluation at that time. This report is intended to draw attention to the need for further evaluation in patients with large renal masses, as well as patients with moderate to high recurrence risk scores.

Various Approaches and Treatments for Pelvic Organ Prolapse in Women

Pelvic organ prolapse (POP) is bulging of one or more of the pelvic organs into the vagina and triggered by multiple causes. It is a very common disorder, especially among older women. POP is characterized by protrusion of the presentation part visible by the naked eye, and problems with urination or bowel movements. POP can be diagnosed based on the onset of symptoms and a pelvic exam, and management options include medical and surgical treatment. Although medical treatment cannot correct the abnormal herniation of the pelvic structures, this can help alleviate symptoms. One of the disadvantages of surgical interventions is recurrence, and advances in surgical techniques have decreased recurrence rates of POP. Therefore, author will explain the gynecology and urology approach and treatment.

Burned-Out Testicular Choriocarcinoma with Retroperitoneal and Liver Metastases

Spontaneous regression or the ‘burned-out’ phenomenon of testicular germ cell tumors is well-recognized but a rare clinical entity of which few reports exist. Tumors with the ‘burned-out’ phenomenon are found in metastatic sites, not in the testis. We report a 33-year-old patient who presented with liver choriocarcinoma and a retroperitoneal mass with the ‘burned-out’ phenomenon in the testis.

Metastasis of Renal Cell Carcinoma to the Bladder

Renal cell carcinoma is an uncommon source of bladder metastases. Here we report a case of renal cell carcinoma that metastasized to the bladder. A 73-year-old woman complained of gross hematuria. Abdominopelvic computerized tomography showed a bladder mass and a heterogenous enhancing mass in the lower pole of the left kidney with left vein thrombosis. The pathological analysis of the resected bladder specimen revealed metastatic renal cell carcinoma of the clear cell type.

Category Migration of Renal Cystic Masses with Use of Gadolinium-Enhanced Magnetic Resonance Imaging

The Bosniak renal cyst classification has been accepted by urologists and radiologists as a way of diagnosing cystic renal masses and determining the management approach. We report two cases of a renal cystic mass that showed a category change from category II on the basis of enhanced computed tomography to category IV after further gadolinium-enhanced magnetic resonance imaging. In both cases, the cysts were later confirmed as kidney cancer by pathology.

Skeletal Muscle Metastases from Urothelial Cell Carcinoma

Hematogenous metastasis to skeletal muscle from urothelial carcinoma is extremely rare and metastatic disease to skeletal muscle tends to be found in people with advanced-stage neoplasm. We report in this paper a case of left sartorius muscle metastasis from urothelial cell carcinoma. A left nephroureterectomy with bladder cuff excision was performed and revealed a high-grade papillary transitional cell carcinoma (TCC) of the pelvis. And 6 month later, recurrent bladder cancer was found regular cystoscopy and then treated with transurethral resection of the bladder. After 6 times resection of bladder, an invasion into the bladder muscle layer was found. We recommended additional radical cystectomy to prevent the disease from advancing. However, the patient refused additional surgery. 6 month later, the patient complained of left thigh pain, so ultrasonography-guided biopsy of the nodular mass lesion in the left sartorius muscle was performed. The pathological analysis of the biopsy specimen revealed poorly differentiated metastatic urothelial carcinoma.

Myotonic Dystrophy Type 1 Presenting as Male Infertility

Myotonic dystrophy 1 (DM1) is a multi-system disorder characterized by endocrine defects that include testicular and tubular atrophy, oligospermia and azoospermia, and increased follicle-stimulating hormone levels. We describe a rare case of DM1 presenting as infertility in a 29-year-old man.

Spontaneously Ruptured Renal Cell Carcinoma During Hemodialysis in Two Patients with End-Stage Renal Disease

Spontaneously ruptured renal cell carcinoma (RCC) in end-stage kidney disease is very rare. Preoperative diagnosis is difficult because of the relatively small tumor size, associated hematoma, and surrounding acquired cysts. Two middle-aged men who were maintained on hemodialysis (HD) for over 10 years suddenly developed flank pain during HD. Computed tomography scans revealed an enhancing ruptured renal mass in one patient, and no obvious tumor lesion except for a hematoma in the other, both of which were later confirmed as RCCs by pathologic specimens.

Ovarian Cystadenoma Mistaken as Postvoid Residual Urine by Portable Ultrasound Scanning

Residual urine can be erroneously estimated due to cystic pelvic pathology by portable ultrasound scanning. We report a case involving a false-positive elevated postvoid residual urine result using a bladder ultrasound caused by an ovarian cystadenoma unrelated to the urinary tract.
