RESUMO
BACKGROUND: We present a case involving a pregnant woman who needed transurethral lithotripsy for ureteral stent removal because of the stent encrustation. CLINICAL CASE: A 34-year-old woman was diagnosed with calculous pyelonephritis, and a double-loop ureteral stent was placed in her right ureter, after which the pyelonephritis resolved. One week after her delivery, we attempted to remove the ureteral stent; however, the encrustation of the proximal and distal coils made it impossible. We then crushed the encrustation by transurethral lithotripsy and removed the ureteral stent successfully. The encrustation component was calcium phosphate, and the urinary pH during pregnancy and after delivery was 7.5. CONCLUSION: Even in pregnant patients, patients placed ureteral stents for obstructive pyelonephritis with high urine pH might need to be replaced in the short term due to concerns regarding phosphate encrustation.

Introduction: A previous report has shown that cyclooxygenase-2 inhibitors can prevent the recurrence of cystitis glandularis postoperatively. Herein, we present a case of cystitis glandularis in which the tumor volume was markedly reduced by preoperative oral administration of a cyclooxygenase-2 inhibitor. Case presentation: A 45-year-old man with voiding difficulty and lower abdominal pain during urination was referred to our hospital. Cystoscopy revealed multiple cystitis glandularis-like edematous masses on the trigone and the neck of the bladder, completely involving the bilateral ureteral orifices. Cyclooxygenase-2 inhibitor was orally administered at the patient's request. Six weeks later, the tumor volume was markedly reduced, bilateral ureteral orifices were identified, and the voiding difficulty and pain on urination disappeared. Complete transurethral resection of the residual tumor was performed, and the pathological diagnosis was intestinal-type cystitis glandularis. Conclusion: Cyclooxygenase-2 inhibition can be considered a useful therapeutic strategy for cystitis glandularis.
RESUMO
We report a case of retroperitoneal laparoscopic radical nephrectomy (LRN) in which the addition of a hand port was necessary and effective. A 52-year-old man with obesity (BMI 40.6 kg/m2) was diagnosed with a 52-mm left renal cell carcinoma (cT1bN0M0). To avoid thick subcutaneous and visceral fat in the abdomen, we selected LRN using a retroperitoneal approach with four ports in the kidney position. During surgery, a large amount of flank pad and perirenal fat prevented us from securing a sufficient surgical field through traction of the kidney with a retractor. A pure laparoscopic procedure was not feasible;therefore, we added a hand port. Subsequently, we removed the flank pad from the hand port and secured the surgical field by tracing the kidney manually. Finally, hand-assisted LRN was completed without an open conversion. In retroperitoneal LRN, we rarely encounter patients for whom a pure laparoscopic procedure is not feasible because of the large amount of flank pad or perirenal fat. It is important to preoperatively confirm not only the BMI but also the amount of flank pad and perirenal fat on imaging. Hand-assisted LRN via the retroperitoneal approach can be safely performed even in extremely obese patients. J. Med. Invest. 71 : 187-190, February, 2024.

Introduction: We present the case of a rapidly growing inferior vena cava tumor thrombus in renal cell carcinoma. Case presentation: We present a case of a 66-year-old woman with right renal cell carcinoma with a tumor thrombus extending 2 cm into the inferior vena cava on an initial Imaging. Radical surgery was performed 6 weeks after the first visit. Intraoperatively, the tumor thrombus was confirmed to have grown near the diaphragm. The tumor was resected using an inferior vena cava clamping just below the diaphragm. The tumor thrombus and renal cell carcinoma were completely removed. There was no recurrence 6 months postoperatively. Conclusion: Inferior vena cava tumor thrombus in renal cell carcinoma can grow in a short period, suggesting that preoperative imaging evaluation at the appropriate time is important. Once inferior vena cava tumor thrombus of renal cell carcinoma occurs, surgery should not be delayed unless there is an urgent reason.
RESUMO
Background: Epididymal injuries without ipsilateral injuries of the testicles are rare. We report a case of a solitary right epididymal injury complicated by left testicular rupture. Case Presentation: A 21-year-old man experienced scrotal trauma caused by a motorcycle accident. Bilateral swelling and tenderness of the scrotum were observed. Ultrasonography and computed tomography revealed a ruptured left testicle; therefore, surgery was performed. During surgery, the left testicle was excised because it was completely ruptured, and the right testicle and epididymis were evaluated to identify the cause of swelling of the right scrotum. The right testis was not injured; however, the right epididymis was lacerated. Subsequently, the lacerated right epididymis was repaired using sutures. A semen analysis performed at 1, 4, and 7 months after surgery revealed the absence of sperm in the semen. Conclusion: Epididymal injuries should be considered as differential diagnoses for scrotal trauma.
RESUMO
A 65-year-old man was admitted to our institution with vomiting and right flank pain. Computed tomography (CT) imaging showed a 21-cm retroperitoneal multilocular cystic tumor which had been identified four years previously. It had increased from 17 to 21 cm. The initial diagnosis was cystic lymphangioma because it was a clear cystic tumor without a boundary or a solid component in the first CT, but later CT revealed an unclear boundary with surrounding organs suggesting malignancy. We decided to resect the tumor because it was symptomatic and might be malignant. The tumor was then resected along with surrounding organs because invasion was suspected. Pathological findings indicated a diagnosis of cystic lymphangioma with chronic inflammation and confirmed complete resection of the tumor. The patient has remained free of recurrence at one year after surgery. This experience indicates that cystic lymphangioma should be completely resected to prevent recurrence.
