Usefulness of Mesh Reinforcement in Pubic Fixation Urethral Sling Surgery for Urinary Incontinence After Radical Prostatectomy.

Objectives: In our institution, a unique sling technique is performed for urinary incontinence after radical prostatectomy. However, in cases of severe urinary incontinence or in the medium to long term, the therapeutic effect may be insufficient. Therefore, a urethral sling technique that provides stronger compression of the bulbar urethra was developed, and its effectiveness was compared with the conventional technique.

A Case in Which a Urethral Catheter Could Be Indwelled by an Anterograde Approach After It Was Difficult to Indwell at the Start of Robot-Assisted Laparoscopic Radical Prostatectomy.

A case in which a urethral catheter could not be indwelled at the start of robot-assisted laparoscopic radical prostatectomy (RARP) is reported. A 64-year-old man was admitted to the hospital for RARP with a diagnosis of prostate cancer cT2aN0M0. At the start of RARP, a pseudo-urethra was formed by inserting a urethral catheter, so surgery was started with a transabdominal posterior approach without indwelling the urethral catheter.

A case of complete resection of prostate stromal sarcoma after neoadjuvant chemotherapy.

Introduction: Prostatic stromal sarcoma is an extremely rare malignancy of the prostate with a poor prognosis.

Case Presentation: A 65-year-old man presented with dyschezia, and computed tomography showed a large prostate mass. The diagnosis was prostate stromal sarcoma by transrectal needle biopsy.

Nivolumab therapy for metastatic collecting duct carcinoma after nephrectomy: A case report.

Rationale: Collecting duct carcinoma (CDC) is a rare type of nonclear renal cell carcinoma, often presenting at an advanced stage of the disease, and standard treatment guidelines have not been established.

Patient Concerns: A 73-year-old man was admitted to our hospital with complaints of fever and lower right back pain.

Diagnoses: Computed tomography revealed a poorly defined tumor of the right kidney without metastasis.

Increased Na reabsorption via the Na-Cl cotransporter in autosomal recessive pseudohypoaldosteronism.

Background: The autosomal recessive form of pseudohypoaldosteronism type 1 (AR-PHA1) is caused by loss-of-function mutations in the epithelial sodium channel subunit genes and is characterized by a multisystemic and lifelong severe salt-wasting tendency. However, we observed a male AR-PHA1 patient who exhibited less frequent salt wasting with advancing age, despite the cessation of daily salt supplementation.

Objective: To elucidate the mechanism for the above phenomenon.
