[A Case of Systemic Polyarteritis Nodosa Presenting with Scrotal Pain].

Hinyokika Kiyo 2019 Apr;65(4):127-131

The Department of Urology, Kobe City Medical Center General Hospital.

A 76-year-old man with a history of hypertension was admitted with high fever and left scrotal pain. Laboratory findings revealed high serum C-reactive protein levels. The left epididymis appeared to be swollen on computed tomography. The patient was diagnosed with bacterial epididymitis and treatment with antibiotics was initiated. Despite treatment, his left scrotal pain and fever did not improve. Additionally, he developed right scrotal and posterior neck pain. For histopathological diagnosis, a left high orchiectomy was performed and the findings revealed thickened arteriolar walls with infiltration of inflammatory cells around the testis, leading to a final diagnosis of systemic polyarteritis nodosa. Treatment with steroids led to complete resolution of the patient's systemic pain and inflammation.

[A Case of Renal Oncocytosis with Bilateral Multiple Renal Masses].

Hinyokika Kiyo 2019 Apr;65(4):111-116

The Department of Pathology, Kobe City Medical Center General Hospital.

A 63-year-old man with microscopic hematuria underwent contrast-enhanced CT, which showed multiple bilateral renal masses. Percutaneous biopsy results indicated renal oncocytosis. The tumors remained unchanged for 3 years. Renal oncocytosis is a very rare tumor, but it is an established disease entity characterized by numerous oncocytic tumors and diffuse (sporadic) renal parenchymal epithelial oncocytic changes on an analysis histopathology. Although renal oncocytosis can be sporadic or part of Birt-Hogg-Dube syndrome (BHDS), our case did not associate with BHDS because of absence of lung cyst.

[Clinical Study of HoLEP for the Patients with Benign Prostatic Hyperplasia who are on Oral Antithrombotics].

Hinyokika Kiyo 2017 Aug;63(8):307-311

The Department of Urology, Kobe City Medical Center General Hospital.

Recently, holmium laserenucleation of the prostate (HoLEP) was associated with less bleeding compared with transurethral resection of prostate. Since 2012, we have performed HoLEP for benign prostatic hyperplasia (BPH) under continuous oral antithrombotics (OA). Between October 2004 and March 2015, 54 patients with BPH underwent HoLEP while on OA at our hospital. Eight patients underwent HoLEP without OA cessation and 46 patients with temporary OA cessation. No significant between-group difference was observed in age, prostate volume, transitional zone prostate volume, operation time, resection weight, resection weight per minute, urethral catheter duration, Hb decrease on day 1 post- HoLEP, hospital stay after HoLEP, bleeding intraoperative rate, bleeding rate after HoLEP and transfusion rate. None presented embolic complications. HoLEP was safe without OA cessation. However, highvolume BPH patients without OA cessation required intraoperative transfusion. Thus, high-volume BPH patients may benefit from OA cessation.
