The adenocarcinoma is a rare istologic type of bladder cancer. A particular subset, the "signet ring cell carcinoma", can have the clinical expression of bladder linitis plastica. In the metastatic form this evenience is very rare and only two cases are reported in the literature. The Authors describe third case.
A retrospective study was carried out using sexual case histories, hormonal profiles, vasoactive drugs test, dynamic cavernosometry and cavernosography on 46 patients who underwent radical cystectomy (26 patients: 57%) and radical prostatectomy (20 patients: 43%) for neoplasia, conducted by means of traditional surgical non-nerve sparing methods, in order to characterize the type of damage affecting the erectile function as a result of surgery. The study was carried out at a minimum of 2 months, a maximum of 9 years and 5 months, an average of 2 years and 6 months, after surgery. One patient (2%) reported intact erectile function and withdrew from the study. 37 patients (80%) showed neurological damage, while the remaining 8 (18%) had prevalently vascular damage.
Ureteral malformations that concern adults are very few. The aim of this review is to value the real clinical incidence and to illustrate etiology, diagnosis and therapeutical management advised in the literature.
We relate our experience about ureteritis, especially non specific ureteritis. The traumatic, radiation ureteritis will be discussed in others chapters. Most cases of ureteritis are infective, and may be due to any of the organism normally found in urinary tract infections, particularly Escherichia Coli, staphylococci, streptococci, enterococci, proteus and pyocyaneus. It is really primary, but it usually ascending from an associated cystitis, descending from pyelonephritis, or due to direct spread from and adjacent inflammatory lesion such as appendicitis or salpingitis. The infection may also reach the ureter by lymphatic spread, particularly from the prostate and seminal vesicles. Any associated abnormalities of the ureter, such as stricture, megaloureter, ureterocele, and so on, will naturally predispose to infective ureteritis. As ureteritis is rarely primary, the first step in treatment must be toward the elucidation and cure of any underlying lesion. Thus calculi, cystitis, pyelitis, and so on, will need appropriate therapy, and this in itself will considerably improve or cure the ureteritis, and specially in the more acute cases. In the chronic cases with stricture formation, dilation or even excision of the stenosed portion may be required. For the treatment of the strictures we want emphasize the role of the ureteral stenting thinking its use is necessary to preserve the renal function.
From January 1987 to October 1990, 20 patients (16 M. 4 F.) affect by localized renal cell carcinoma, underwent a conservative surgical treatment. This case study includes 8 patients with bilateral (4 synchronous-4 asynchronous), and 12 patients with unilateral renal carcinoma. In the latter group only two patients had a pathological contralateral kidney. A parenchyma sparing operation was performed electively in 10 cases and was necessary in the other 10. The tumors were found to be PT1 or pT2 in all the elective cases, except one unexpected pT3a; 1pT1, 5pT2, 1pT3a and 3pT3b in the remaining group. The follow up ranges between 1 and 36 months, two deaths in bilateral tumors cases were observed. No local recurrences have been detected up to now.
