Long-term recurrence-free survivor after laparoscopic removal of solitary adrenal metastasis from endometrial adenocarcinoma.

Solitary adrenal metastasis from endometrial adenocarcinoma is extremely rare. We report herein the case of a laparoscopically resected solitary adrenal metastasis originating from endometrial adenocarcinoma. The patient was a 55-year-old woman who had undergone total abdominal hysterectomy for stage IIIc endometrial carcinoma, followed by 7 courses of adjuvant chemotherapy comprising carboplatin and paclitaxel.

[A case of retroperitoneal serous cyst resected by laparoscopic surgery].

A 40-year-old woman was referred to our hospital because of pain extending from the left lateral abdomen to the left inferior limb. The abdominal computed tomography (CT) revealed an 8x7x12 cm retroperitoneal serous cystic mass. The serum carcinoembryogenic antigen (CEA) level was slightly elevated to 2.

[Clinical study of prostate specific antigen failure after radical prostatectomy for prostate cancer: a single center experience].

Between January 1996 and December 2007, 111 patients with prostate cancer underwent radical prostatectomy, including 34 who received preoperative hormonal therapy. In this study, we reviewed 77 patients who did not undergo neoadjuvant hormonal therapy. The mean age was 65.

Low transscrotal orchidopexy is a safe and effective approach for undescended testes distal to the external inguinal ring.

Objectives: To review the results of a low transscrotal orchidopexy in patients with palpable undescended testes located distal to the external inguinal ring.

Methods: Between July 1998 and June 2005, transscrotal orchidopexy with a single low scrotal incision was performed in 32 patients for 49 undescended testes. The indication was an undescended testis that lay distal to the external ring and could be pulled down manually into the scrotum under general anesthesia.

Transperitoneal versus retroperitoneal laparoscopic radical nephrectomy: a comparative study.

Objectives: To compare perioperative outcome of transperitoneal and retroperitoneal approaches during laparoscopic radical nephrectomy (LRN) and to identify selection criteria for each approach.

Methods: Over a 7-year period, 100 consecutive patients (median age 62 years, range 20-80) underwent LRN for a renal tumor with clinical stage T1a-T3a. The first choice approach was retroperitoneal.

[Laparoscopic ureterolithotomy for ureteral calculi: three case reports].

With the development of extracorporeal shock wave lithotripsy (ESWL), improved endourologic instrumentation, and medical dissolution therapy, the need for open ureterolithotomy has become less common. Open operation is occasionally necessary when less invasive techniques fail. As in many of the surgical specialties, laparoscopy has become more common in urologic surgery.

[Case of tuberculous epididymitis caused by intravesical BCG therapy].

Intravesical Bacillus Calmette-Guerin (BCG) therapy is commonly used against superficial urothelial carcinoma, especially carcinoma in situ (CIS). We report a case of tuberculous epididymitis that occurred during a course of intravesical BCG therapy. A 76-year-old man had received intravesical BCG therapy for multiple superficial bladder cancer and CIS in prostatic urethra after transurethral resection of bladder tumor (TUR-Bt).

Strategy for repeat prostate biopsy: predictors of positive biopsy and additional biopsy location.

Purpose: We analyzed patterns of tumor distribution in radical prostatectomy specimens from patients with repeat biopsies to determine additional appropriate biopsy locations for repeat biopsy.

Methods: Between January 2000 and June 2005, a total of 382 patients underwent transrectal ultrasound-guided prostate biopsy. Of these, 47 patients underwent repeat biopsy.

Prognostic significance of serum hepatocyte growth factor in clear cell renal cell carcinoma: comparison with serum vascular endothelial growth factor.

No adequate serum predictive biomarker currently exists, which can identify the activity of renal cell carcinoma (RCC). We investigate the association of serum hepatocyte growth factor (HGF) and serum vascular endothelial growth factor (VEGF) levels with clinicopathologic parameters in untreated clear cell RCC patients. We measured serum levels of HGF and VEGF in 45 patients with untreated clear cell RCC and 45 healthy controls using an enzyme-linked immunosorbent assay (ELISA).

Massive leiomyosarcoma of the spermatic cord.

A 56-year-old man was diagnosed with a right testicular tumor. Orchiectomy with high ligation of the spermatic cord was performed. Histological examination revealed leiomyosarcoma of the spermatic cord.

Role of phosphatidylinositol-3 kinase/Akt pathway in bladder cancer cell apoptosis induced by tumor necrosis factor-related apoptosis-inducing ligand.

TRAIL/Apo2L is a pro-apoptotic cytokine that is capable of inducing apoptosis in a wide variety of cancer cells but not in normal cells. Among various molecular strategies by which cancer cells evade apoptosis, PI3K/Akt signaling represents a dominant survival pathway. In this report, we investigated the role of PI3K/Akt pathway in TRAIL-induced apoptotic death in human bladder cancer cells.

[A non-seminomatous extra-gonadal germ cell tumor responding to intensive treatment: a case report].

A 23-year-old man presented with lumbago as a chief complaint. Computed tomographic (CT) scan revealed multiple lung tumors, multiple liver tumors, bulky retroperitoneal tumors with marked elevation of serum lactic dehydrogenase (LDH), alpha-fetoprotein, and beta subunit of human chorionic gonadotropin (HCG-beta). The patient was referred to our hospital for treatment.

Clinical research of renal vein control using Hem-o-lok clips in laparoscopic nephrectomy.

Control of the renal vein represents a crucial step in laparoscopic nephrectomy. Although endovascular gastrointestinal anastomosis (GIA) staplers have generally been used for renal vein control because of the large diameter of the vessel, Hem-o-lok clips have recently been used for renal artery control. GIA staplers are expensive and can malfunction on rare occasions, resulting in severe complications.

Bilateral adrenal myelolipoma associated with adrenogenital syndrome.

Adrenal myelolipoma is a rare benign tumor, occasionally reported in association with endocrine disorders. We report herein a case of bilateral adrenal myelolipoma associated with adrenogenital syndrome caused by 21-hydroxylase deficiency. A diagnosis of 21-hydroxylase deficiency was confirmed by mutation analysis of the CYP21 gene.

Indications for laparoscopic adrenalectomy for non-functional adrenal tumor with hypertension: usefulness of adrenocortical scintigraphy.

Aim: Laparoscopic adrenalectomy is currently indicated for biochemically and clinically functional adrenal tumors and potentially malignant tumors of the adrenal glands. Non-functional adenomas greater than 5 cm in diameter of the adrenal gland are generally considered to represent potentially malignant tumors. The present study shows indications of laparoscopic adrenalectomy for non-functional adrenal tumors with hypertension in a retrospective fashion.

[A case of renal capsular hemangiosarcoma].

We report herein a case of renal capsular hemangiosarcoma. A 68-year-old man was admitted to our hospital for treatment of a retroperitoneal tumor identified incidentally on abdominal computed tomography (CT) for follow-up of superficial bladder tumor. The tumor was about 7cm in diameter, positioned between the right kidney and the liver.
