Inappropriate antidiuretic hormone secretion syndrome can be a serious adverse event of cisplatin-based chemotherapy. Cisplatin had to be changed to other drugs or chemotherapy completely discontinued in earlier reported cases.

Three cycles of bleomycin, etoposide, and cisplatin chemotherapy were planned for a 40-year-old man with a diagnosis of lymph node recurrence of testicular cancer. On day 9, he suffered from vomiting and mental disturbance. Severe hyponatremia (110mEq/L) with low plasma osmolality led to a diagnosis of a syndrome of inappropriate antidiuretic hormone secretion, and infusions of hypertonic saline and salt intake were prescribed. Second and third courses of bleomycin, etoposide, and cisplatin chemotherapy could then be given with careful electrolyte management.

Continuation of cisplatin administration with precise electrolyte adjustment can be a treatment option in regimens where cisplatin is essential for achieving optimal antitumor efficacy.

Severe penile torsion of 180° associated with hypospadias is a rare entity. Knowledge of penile anatomy and pathology are necessary as the diagnosis could be missed.

We report a case of severe 180° penile torsion with distal hypospadias that was mistaken for an epispadias which was corrected with surgery.

Tubularized incised plate urethroplasty and dartos flap rotation provided satisfactory result for this association.

Pyelovenous backflow is a rare condition resulting from an increase in pressure in the renal pelvis due to urinary obstruction.

A 49-year-old woman developed high-grade fever and right-sided hydronephrosis after undergoing hysterectomy. Although the hydronephrosis was mild, retrograde pyelography revealed complete obstruction of the right ureter. Excretory phase scans of contrast-enhanced computed tomography showed pyelovenous backflow, which presumably decompressed the hydronephrosis. The pyelovenous backflow immediately disappeared after ureteroneocystostomy.

We were presented with a patient showing pyelovenous backflow detected by contrast-enhanced computed tomography, which completely disappeared after ureteral obstruction release.

Pneumatosis cystoides intestinalis is a rare condition characterized by air-filled cysts within intestinal walls. It can be caused by various factors. We report a case of pneumatosis cystoides intestinalis linked to sunitinib treatment for renal cell carcinoma.

A 67-year-old female with advanced renal cell carcinoma who had been treated with sunitinib visited our hospital complaining of abdominal pain. Computed tomography scans showed diffuse air-filled cystic formation of intestine. click here We treated with conservative therapy, and she recovered. However, although air-filled cysts disappeared in the images, intraoperative findings in the resection of a recurrent paracaval lymph node showed a thinning of the intestine.

It is necessary to consider pneumatosis cystoides intestinalis when a patient using a tyrosine kinase inhibitor complains of abdominal symptoms. It should also be noted that the effect of pneumatosis cystoides intestinalis may remain even if pneumatosis disappears from the image on tomography scans.

Transurethral resection of bladder tumor is widely used in combination with photodynamic diagnosis to treat non-muscle invasive bladder cancer. We experienced an intriguing case, in which bladder cancer infiltrated into the right ureteral orifice and was resected via photodynamic diagnosis-assisted transurethral resection involving the oral administration of 5-aminolevulinic acid.

This case was a 71-year-old Japanese man. He was diagnosed with bladder carcinoma, which had infiltrated into the right ureter (clinical classification T1, N0, M0). He underwent transurethral resection involving the oral administration of 5-aminolevulinic acid. We successfully resected the tumor in the ureteral orifice, which was accomplished by resecting the ureteral orifice until the non-luminescent lumen was exposed. After the surgery,to prevent recurrence, Bacillus Calmette-Guérin was administered intravesically after right ureteral stent placement.

Photodynamic diagnosis-assisted transurethral resection involving the oral administration of 5-aminolevulinic acid has the potential to treat ureteral tumors derived from bladder tumors.

Horseshoe kidney has unique anatomical features, such as a complex blood supply. We report a patient with renal cell carcinoma in a horseshoe kidney, who underwent tumor resection by robot-assisted laparoscopic partial nephrectomy based on preoperative three-dimensional computed tomography.

A 66-year-old man was referred to our hospital with a 2-cm enhancing mid-pole mass in the left moiety of a horseshoe kidney. The clinical diagnosis was renal cell carcinoma cT1aN0M0 (R.E.N.A.L. nephrometry score 1+2+3+3=9p). Robot-assisted laparoscopic partial nephrectomy was performed with selective clamping based on reconstructed three-dimensional images. The warm ischemia time was 13min. Pathologic examination confirmed a diagnosis of pT1a clear cell renal cell carcinoma with negative surgical margins. At 6months postoperatively, computed tomography showed no local recurrence or metastasis and renal function was intact.

Robot-assisted laparoscopic partial nephrectomy with preoperative three-dimensional computed tomography may have advantages for resection of tumors in patients with horseshoe kidney.
