Female pelvic organ-preserving robot-assisted simple cystectomy and intracorporeal ileal neobladder reconstruction on a young woman with Hunner-type interstitial cystitis.

Introduction: Cystectomy is the last treatment option for Hunner-type interstitial cystitis. However, consensus regarding optimal patient selection or treatment approaches is lacking. Case presentation: A 27-year-old woman presented to a regional hospital with bladder pain and frequent urination. Antimicrobial therapy was administered; however, her symptoms persisted and she was finally diagnosed with HIC. Multiple endoscopic fulgurations of Hunner's lesions with bladder hydrodistension or intravesical therapy were performed; however, the symptoms persisted. A urethral catheter was inserted 1 month before she visited our clinic because of a severely contracted bladder. We performed female pelvic organ-preserving robot-assisted simple cystectomy and intracorporeal ileal neobladder reconstruction. The patient's postoperative course was uneventful and her symptoms resolved. Conclusion: This is the first report of pelvic organ-preserving robot-assisted simple cystectomy and intracorporeal ileal neobladder reconstruction in a young woman with HIC.

[A CASE OF PRIMARY MUCOSA-ASSOCIATED LYMPHOID TISSUE (MALT) LYMPHOMA OF THE URINARY BLADDER].

A 68-year-old female presented with macroscopic hematuria. Cystoscopy revealed a wide-based submucosal mass. Computed tomography revealed a 3.5 × 2.5-cm solitary mass situated from the trigone to the left lateral bladder wall and the left hydroureter and hydronephrosis. T2-weighted magnetic resonance imaging (MRI) revealed low intensity, and diffusion-weighed MRI showed increased diffusion without invasion. The bladder tumor was immediately resected transurethrally. Histological diagnosis of the tissue obtained by transurethral resection was extranodal marginal zone B cell lymphoma of MALT. Positron emission tomography-CT showed no lesions other than the bladder tumor. The patient was diagnosed with stage-IE lymphoma of the bladder (Ann Arbor classification). Radiotherapy was performed at the bladder and pelvis (30 Gy) with six courses of rituximab (375 mg/m2). No local or distant recurrence after a 48-month follow-up was noted.

[A Case Report of 2,8-Dihydroxyadenine Urolithiasis].

We report a case of 2,8-dihydroxyadenine (DHA) urolithiasis in a 65-year-old male. He initially visited another institution because right hydronephrosis was revealed in a medical checkup. Computed tomography demonstrated radiolucent right renal stones. We performed percutaneous nephrolithotripsy and flexible transurethral lithotripsy and removed the stones successfully. An analysis of the stone fragments revealed 2,8-DHA urolithiasis. 2,8-DHA stones are relatively rare and caused by adenine phosphoribosyltransferase deficiency.
