RESUMEN
OBJECTIVE: Review of the Guidelines which have major impact on the urological field, in order to compare and to know their recommendations in the diagnosis and management of biochemical relapse after a healing treatment of prostate cancer (radical prostatectomy or radiotherapy). METHODS: We review the Guidelines of the European Urological Association (EAU), the American Urological Association (AUA), of the National Comprehensive Cancer Network (NCCN) and those of the National Institute for Health and Clinical Excellence (NICE), as well as the scientific evidence on which they are based. RESULTS: In this paper we state the complexity of the subject being dealt with and coincidences and differences among them. The definition of relapse varies depending on whether the patient has undergone either radical prostatectomy or radiotherapy. Regarding treatment, in the first case early radiotherapy is the treatment of choice, but recommendations after radiotherapy are not so specific. CONCLUSION: Clinical Guidelines represent a great aid in decision making for the professional. Guidelines give recommendations with a higher o lower degree of scientific evidence and must be evaluated regularly to include new evidences which are coming through.

PURPOSE: The study investigated factors that affect operating times and bleeding complications associated with percutaneous nephrolithotomy (PCNL) in the PCNL Global Study. PATIENTS AND METHODS: All patients who underwent PCNL for primary or secondary treatment of kidney stone indications during the study period (November 2007-December 2009) were eligible for inclusion. PCNL procedures were performed according to local clinical guidelines and practices. Nephrostomy tract dilation was performed using balloon dilation, metal telescopic dilation, or Amplatz serial dilation. Hematologic complications assessed included bleeding rates, transfusion rates, and preoperative and postoperative hematocrit values. RESULTS: The median operating time with balloon dilation (n=2277) was significantly longer than with telescopic/serial dilation (n=3260) at 94.0 vs 60.0 minutes, respectively (P<0.0001). In the balloon dilation group, there was significantly more bleeding (9.4% vs 6.7%, respectively; P<0.0001) and more transfusions (7.0% vs 4.9%, respectively; P=0.001) compared with the telescopic/serial dilator group. Univariate analysis showed that the probability of bleeding complications was higher with balloon vs telescopic/serial dilation (odds ratio [OR] 1.75; P=0.0001) and larger sheath size (OR 1.42; P=0.0001). By multivariate analysis, sheath size but not dilation method was predictive of bleeding complications. Other significant predictive factors included operating time, stone load, and caseload. CONCLUSION: This study shows that in PCNL, factors that are associated with bleeding/transfusion include sheath size, operating time, stone load, and caseload.
