[Real-World Experience and Complications with Intermittent Balloon Catheters : A Predictor Analysis].

Intermittent balloon catheterization with a reusable and temporary balloon catheter that could be implanted and removed by the patient was developed in Japan in 1995. Although the intermittent balloon catheter has the potential to improve the patient's quality of life (QOL), appropriate information and guidelines are needed to prevent complications such as hematuria and urinary tract infection. This study aimed to assess the real-world practice, complications, and problems associated with the use of intermittent balloon catheters and provide useful information for future medical care. We conducted a questionnaire survey on patients with spinal cord lesions who currently use or have used intermittent balloon catheters in the past. Seventy-six patients with spinal cord lesions who visited Kanagawa Rehabilitation Hospital from August 2020 to March 2021 and gave consent for participating in this study were included. QOL scores before and after intermittent balloon catheter use showed significant improvement after use. Forty-six of the 76 (61.3%) patients had complications. Overall complications were significantly associated with male sex and possibly linked to non-traumatic spinal cord lesions.

A huge bladder calculus causing acute renal failure.

A 81-year-old male was referred to our emergency outpatient unit due to acute renal failure. The level of serum creatinine was 276 µmol/l. A CT scan showed bilateral hydronephroureter, large bladder stone (7 cm × 6 cm × 6 cm) and bladder wall thickness. He was diagnosed as post renal failure due to bilateral hydronephroureter. Large bladder stone is thought to be the cause of bilateral hydronephroureter and renal failure. To improve renal failure, we performed open cystolithotomy and urethral catheterization. Three days after the surgery, the level of serum creatinine decreased to 224 µmol/l. He was discharged from our hospital with uneventful course. Bladder calculus is thought to be a rare cause of renal failure. We summarize the characteristics of bladder calculus causing renal failure. We should keep that long-term pyuria and urinary symptom, and repeated urinary tract infection can cause huge bladder calculus and renal failure in mind.

A case of metastatic prostate adenocarcinoma to an inguinal lymph node.

A 47-year-old man presented with dysuria. The prostate-specific antigen level was 65.5 ng/mL. Retropubic radical prostatectomy and regional lymphadenectomy revealed moderately differentiated adenocarcinoma (Gleason score 3 + 4 = 7, pT2N0). Postoperative adjuvant hormonal therapy was started immediately. Three years later, hormonal therapy was changed to anti-androgen monotherapy. Monotherapy was continued for eight years and then discontinued because the PSA level was maintained at <0.04 ng/mL. However, biochemical recurrence occurred 12 months after adjuvant hormonal therapy was discontinued. A computed tomography scan showed left inguinal lymphadenopathy. Biopsy of the swollen inguinal lymph node revealed metastatic prostate cancer. We report a rare case of metastatic prostate adenocarcinoma only to the inguinal lymph nodes.
