Introduction: Paraneoplastic syndromes (PNS) may represent the main clinical problem in cancer patients; however, the knowledge of their clinical aspect remains quite poor among urologists. Objective: To provide urologists with an overview on main clinical aspects of PNS that have been reported to be associated to urological cancers. Methods: Literature search of peer-reviewed papers published by July 2008. Results: All genitourinary tumors can cause a PNS, and renal cell carcinoma is the most frequent urological malignancy involved. Prostate cancer is the second urological tumor associated with PNS which, conversely, are uncommon in bladder cancer and rare in testicular cancer. Tumor neuroendocrine differentiation is involved in most endocrine PNS. Neurologic PNS are very uncommon but may dominate the clinical picture and need a high suspicion index to be recognized. Important advances have been made on radionuclide scan methods in order to detect the primary tumor. The most effective treatment strategy is always represented by the radical therapy of the underlying cancer, but specific therapeutic options are sometimes available. Conclusions: Endocrine PNS are frequently associated with urological cancers, especially renal and prostate carcinoma. PNS have been rarely reported in association with cancers of bladder, urethra and testicle.
Since its introduction in 1980, extracorporeal shockwave lithotripsy (SWL) has become the first therapeutic option in most cases of upper-tract urolithiasis, and the technique has been used for pediatric renal stones since the first report of success in 1986. Lithotripter effectiveness depends on the power expressed at the focal point. Closely correlated with the power is the pain produced by the shockwaves. By reducing the dimensions of the focus, it becomes possible to treat the patient without anesthesia or analgesia but at the cost of a higher re-treatment rate. Older children often tolerate SWL under intravenous sedation, and minimal anesthesia is applicable for most patients treated with second- and third-generation lithotripters. Ureteral stenting before SWL has been controversial. Current data suggest that preoperative stent placement should be reserved for a few specific cases. Stone-free rates in pediatric SWL exceed 70% at 3 months, with the rate reaching 100% in many series. Even the low-birth-weight infant can be treated with a stone-free as high as 100%. How can one explain the good results? Possible explanations include the lesser length of the child's ureter, which partially compensates for the narrower lumen. Moreover, the pediatric ureter is more elastic and distensible, which facilitates passage of stone fragments and prevents impaction. Another factor is shockwave reproduction in the body: there is a 10% to 20% damping of shockwave energy as it travels through 6 cm of body tissue, so the small body volume of the child allows the shockwaves to be transmitted with little loss of energy. There are several concerns regarding the possible detrimental effect of shockwaves on growing kidneys. Various renal injures have been documented with all type of lithotripters. On the other hand, several studies have not shown adverse effects. In general, SWL is considered to be the method of choice for managing the majority of urinary stones in children of all ages. Re-treatments improve the stone-free rate, often raising it to 100%. Among the predictors of success, stone size seems to be the most important. In the absence of guidelines, selecting the appropriate treatment modality for each child requires planning and depends on instrument availability and local expertise.
Objective To report the aetiological, diagnostic and therapeutic aspects of penile Mondor's disease treated with non‐steroidal anti‐inflammatory drugs (NSAIDs) or surgery. Patients and methods During the last 3 years, 10 patients (mean age 35 years, range 20–57) were treated for superficial penile vein thrombophlebitis. The main aetiological factors were prolonged and excessive sexual intercourse, operations for inguinal hernia and deep vein thrombosis. All patients had noticed sudden and almost painless cord‐like induration on the penile dorsal surface. Doppler ultrasonography was useful in both diagnosis and follow‐up. Eight patients were treated with NSAIDs and platelet drugs. Results The mean interval to resolution of symptoms was 3 weeks. Two patients who did not respond to drug therapy underwent surgery (dorsal vein resection). Conclusion Medical therapy and, when indicated, vein resection are successful and effective in treating penile Mondor's disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
