Metastatic disease to the ureter is rare. Although it is not often diagnosed during life metastasis to the ureter should be suspected when malignancy and symptoms of ureteral disease are present. We report the thirteenth case of adenocarcinoma of the prostate metastatic to the ureter, which also was associated with a ureteral calculus.

We report on a patient with a known diagnosis of adenocarcinoma of the prostate who had acute renal failure. An excretory urogram showed bilateral ureteral obstruction and retrograde ureteral catheterization was attempted. Because the retrograde catheters could not be passed into the bladder percutaneous nephrostomies were placed immediately. Dissection of the right ureter showed complete intrinsic occlusion by a multinodular tumor, with no evidence of secondary extension at the ureterovesical junction on the right side or circumferential spread along the involved ureter.

The application of minimally invasive laparoscopic surgical techniques has provided the urologist with access to retroperitoneal structures previously available only through an abdominal incision. The enhanced visualization provided by video-imaging as well as the ease of access to the retroperitoneum through an incision in the posterior peritoneal envelope has facilitated the manipulation of many retroperitoneal organs. In particular these techniques have been applied to the clinical management of several urologic malignancies, such as adenocarcinoma of the prostate, transitional cell carcinoma of the bladder, and squamous cell carcinoma of the penis. A transperitoneal laparoscopic pelvic lymphadenectomy appears to provide adequate surgical staging of regional pelvic lymph nodes in these malignancies, while providing the patients with reduced morbidity. Additionally, transperitoneal access may be accomplished for an internal spermatic vein ligation, as well as approaches to the kidney, ureter and retroperitoneal lymph nodes. The surgical options are limited only by the availability of the instrumentation and the creativity of the surgeon. However, the indications for these procedures remain unclear and must await further information regarding actual benefits in the form of reduced patient morbidity and cost. The challenge for the future is to more completely define the indications and selection criteria for laparoscopic surgery.

This report describes the surgical management of 24 patients with concurrent abdominal aortic aneurysm (AAA) and urinary tract neoplasm. The patient population consisted of 22 men and two women whose average age was 65.5 years. AAA sizes ranged from 3.1 to 9.0 cm (mean 5.2 cm) in diameter. Urinary tract neoplasms included transitional cell carcinoma (TCC) of the bladder (n = 19), adenocarcinoma of the prostate (n = 3), and TCC of the renal pelvis (n = 2). Urologic procedures included radical prostatectomy, radical nephroureterectomy, and radical cystoprostatectomy with continent or ileal loop urinary diversion. The AAA was resected at the time of the urologic procedure in 12 patients (group I) or prior to the urologic procedure in five patients (group II) and was left in situ in seven patients (group III: AAA diameter 3.1 to 5.5 cm). All patients but one in group I recovered without complications. One patient developed an infection postoperatively as a result of fluid collection anterior to the aortic vascular graft; the fluid was successfully drained and the patient subsequently recovered uneventfully. All patients in group II had a marked retroperitoneal desmoplastic reaction at the time of the urologic procedure as a result of prior aneurysmectomy, which complicated the ureteral dissection. One patient later required an ileal ureteral reconstruction for obliterative fibrosis of the ureter. At a mean follow-up of 34 months, no infectious or mechanical complications of the vascular prosthesis occurred in group I or II. Eight patients in group I and two in group II are alive. Three have died of metastatic disease and two of myocardial infarction. Of the seven patients in group III, four subsequently required AAA resection for an increase in AAA size and three have died.(ABSTRACT TRUNCATED AT 250 WORDS)

An 86-year-old man was admitted to our hospital with a complaint of gross hematuria. Urological examination revealed right hydronephrosis and poorly differentiated adenocarcinoma of the prostate with bone metastases. Abdominal computed tomographic scan and retrograde pyelography showed thickening of the ureteral wall with irregular stenosis in the right upper ureter. Right nephroureterectomy demonstrated diffuse lymphatic infiltration of PSA-positive cancer cells in the submucosa and muscle layer of the ureter as well as renal pelvis. This is the 6th reported case of metastatic ureteral tumor from prostate cancer in the Japanese literature.

The diagnosis of congenital anomalies of the urogenital tract in the adult is uncommon. Complete ureteral duplication represents a congenital anomaly of the ureters, usually draining a duplex kidney, with a second orifice entering the bladder, urethra or other structures. In the majority of cases, this pathology is completely asymptomatic; sometimes it's diagnosed because of complications such as infections, hydronephrosis, lithiasis, or in the evaluation of the urinary tract. Early diagnosis of localized prostatic adenocarcinoma is increased due to worldwide use of PSA screening and the optimization of multiple biopsy, increasing radical surgery treatments. The association between these two pathologies is a rare event. We present the case of a 69-years old man diagnosed for localized prostatic cancer and bilateral complete ureteral duplication, megaureter and stenosis of left superior ureteral meatus, leading in the prostatic urethra. Terminal ureter with the ectopic meatus opening in prostatic urethra was occupied by stones. A combined surgical procedure was undertaken: radical prostatectomy, ectopic ureter section, lithiasis removal and reimplantation of left ectopic ureter into the bladder. There is no case described of the association of this urogenital anomaly and prostate cancer and the combined management of both.

A 69-year-old male was diagnosed as having prostate cancer with ureter invasion. His serum prostate specific antigen level was not so high (19.6 ng/ml) before treatment, but clinical stage was D2, poorly differentiated adenocarcinoma of prostate. He was treated with chemoendocrine therapy. Prostate cancer with continuous invasion to the middle ureter is rare. To the best of our knowledge, this is the 6th case report of such an unusual invasion of prostate cancer.

A 64-year-old man underwent a radical cystoprostatectomy for intravesical bacillus Calmette-Guerin (BCG) therapy-resistant, recurrent muscle invasive transitional cell carcinoma (TCC) of the urinary bladder. He had a history of left radical nephroureterectomy for a papillary TCC of the left ureter 10 months ago. On microscopic examination, not only multifocal residual papillary TCCs in the urinary bladder but also multiple small granulomas in the urinary bladder and prostate were noted. Interestingly, unusually severe granulomatous inflammation accompanying focal central caseating necrosis was identified in the subepithelial tissue of the left seminal vesicle and vas deferens. Neither prostatic adenocarcinoma nor TCC involvement was identified in the prostate and seminal vesicles. A few acid-fast bacilli were identified by the Ziehl-Neelsen staining in the seminal vesicle granulomas, confirming the BCG-induced inflammation. To the best of our knowledge, this is the first case of BCG-induced granuloma involving the seminal vesicle. It is uncertain why only the left seminal vesicle was involved with BCG granulomas and the incidence and mechanism of seminal vesicle BCG granuloma await more cases.

This article describes an unusual finding in a patient who presented with an adenocarcinoma of the prostate and right hydronephrosis. A 68-year-old male presented with right hydronephrosis and a PSA of 96. DRE was consistent with cT3 carcinoma. Cystoscopy showed an exophytic superficial transitional cell carcinoma (TCC) of the bladder and a transrectal biopsy of the prostate confirmed adenocarcinoma Gleason score 4+3. Staging investigations (CT pelvis and bone scan) were negative; androgen deprivation therapy was therefore initiated for the prostatic adenocarcinoma. Upper tract imaging showed multiple filling defects in the proximal ureter. Ureteroscopy showed a stricture at the level of the iliac vessels. With a working diagnosis of upper tract TCC, right open nephroureterectomy was performed. Final histology showed prostatic adenocarcinoma infiltrating the adventitia of the entire ureter up to the level of the renal pelvis. A rare cause of ureteric stricture, contiguous spread of prostatic adenocarcinoma, should be considered in the differential diagnosis of patients presenting with upper tract obstruction and a known history of prostatic adenocarcinoma. Androgen deprivation therapy for several months did not seem to cause resolution of the tumor in the periureteric, ureteric and perihilar tissues.
