PURPOSE: A great number of small renal lesions have now been detected. Nowadays, partial nephrectomy has more frequently been adopted for surgical treatment of earlier stage disease. Previous studies have associated patient, institutional, and health care system factors with surgery type. The aim of this study was to compare the diagnosis and treatment of renal cell carcinoma (RCC) according to hospital type, public versus private, in our country. MATERIALS AND METHODS: We retrospectively evaluated 183 patients with RCC who underwent radical nephrectomy or nephron-sparing surgery between 2003 and 2007 in two hospitals, one private and one public. Patient demographic, clinical, surgery, and pathologic characteristics were analyzed. RESULTS: The radical nephrectomy rate was higher at the public hospital than at the private hospital (75% vs. 57%, p = 0.008). Overall, patients at the public hospital presented larger tumors than did the patients who were cared for privately. Furthermore, small renal masses were significantly more prevalent in private care (57.8% vs. 28.3%). Patients at the public hospital showed a higher incidence of capsular invasion (p = 0.008), perirenal fat invasion (p < 0.01), lymph node involvement (p < 0.001), and a lower incidence of initial tumors. pT1 tumors were reported in 41% of patients at the public hospital and in 72% at the private hospital (p < 0.001). CONCLUSION: Patients with RCC cared for at our public referral hospital showed a more advanced stage than RCC treated at the private institution.

PURPOSE: The incidence of renal cell carcinoma (RCC) has been rising by 2.3 to 4.3% every year over the past three decades. Previously, RCC has been known as the internist’s tumor; however, it is now being called the radiologist’s tumor because 2/3 are now detected incidentally on abdominal imaging. We compared patients who were treated toward the end of the 20th century to those treated during the beginning of the 21st century with regard to RCC size and type of surgical treatment. MATERIALS AND METHODS: The study included 226 patients. For analysis of tumor size, we considered a cut point of < 4 cm and > 4 cm. For analysis of type of surgery performed, we considered radical and partial nephrectomy. RESULTS: After the turn of the century, there was a reduction of 1.57 ± 0.48 cm in the size of the RCC that was operated on. Nephron sparing surgeries were performed in 17% of the cases until the year 2000, and 39% of the tumors were < 4 cm. From 2001, 64% of the tumors measured < 4 cm and 42% of the surgeries were performed using nephron sparing techniques. Mean tumor size was 5.95 cm (± 3.58) for the cases diagnosed before year 2000, and cases treated after the beginning of 21st century had a mean tumor size of 4.38 cm (± 3.27). CONCLUSIONS: Compared with the end of the 20th century, at the beginning of the 21st century due to a reduction in tumor size it was possible to increase the number of nephron sparing surgeries.

INTRODUCTION: Chronic testicular pain remains an important challenge for urologists. Currently, the treatment plan is primarily empirical, with the first approach consisting of clinical measures. However, some patients remain in pain despite a conservative treatment protocol and, for them, it is possible to perform a surgical procedure that involves severing the scrotal and spermatic branches of the genitofemoral and ilioinguinal nerve fibers. METHODS: In our institution, 60 patients were evaluated and treated for idiopathic chronic testicular pain between January 2003 and July 2007. Priority was give to clinical treatment, which evolved from simple to more complex measures. Microsurgical treatment was performed on those who experienced no considerable pain relief (10 individuals in our study). RESULTS: Over a twenty-four-month follow-up period, 70% of patients showed complete remission and 20% exhibited partial relief from pain.

OBJECTIVE: We aim at determining the prognostic value of squamous differentiation in patients with transitional cell carcinoma (TCC) of the bladder that were treated with radical cystectomy. MATERIALS AND METHODS: From January 1993 to January 2005, we retrospectively selected 113 patients. Correlations among squamous differentiation with other clinical and pathological features were assessed by both chi-square and Fisher tests. The Kaplan-Meier method was used to evaluate survival curves and statistical significance was determined by the log-rank test. Multivariate analysis was performed through a Cox proportional hazards regression model. RESULTS: Squamous differentiation was observed in 25 (22.1%) of the 113 patients. This finding was significantly related only to the pathological stage. Mean follow-up after cystectomy was 31.7 ± 28.5 months. Disease recurrence occurred in 16 (64%) and 30 (34%) patients with and without squamous differentiation (log-rank test, p = 0.001), and mortality occurred in 10 (40%) and 14 (16%) of the patients with and without squamous differentiation respectively. Univariate analysis revealed that pathological stage, squamous differentiation, tumor size and lymph node involvement were significant predictors of cancer-specific survival. However, only squamous differentiation and tumor size were independent prognostic variables on multivariate analysis. CONCLUSIONS: Squamous differentiation was an independent prognostic factor for cancer specific survival in patients with bladder cancer treated with radical cystectomy. Further studies with a larger number of patients are necessary to confirm these results.
