All changes in the register seen over time are consistent with increased diagnostic activity, especially PSA testing, resulting in an increased number of cases with early disease, predominantly tumors in category T1c. The patterns of diagnosis and treatment of prostate cancer vary considerably in different parts of Sweden. The NPCR continues to be an important source for research, epidemiological surveillance of the incidence, diagnosis and treatment of prostate cancer.

Each of 92 patients in a Swedish district served by only one hospital had been treated for their first renal stone in 1977 and was evaluated 10 years later. Recurrent stone formation during the observation period was observed in 26% of the patients, with no difference between men and women. Of all the patients who had sought medical advice in 1977 because of urinary stone colic, 51% were experiencing their first stone episode. Ten years later 37% of the original patients were still classified as single stone formers. The recorded recurrence rate was lower than that previously reported in the literature.

invited to enter the study. The final analysis included 306 patients and 310 controls, all assessed for symptoms and well-being. RESULTSA low or moderate level of well-being was reported by 35% of the patients having none or one of the symptoms studied, by 39% with two symptoms, by 45% with three symptoms and by 66% of those with four or more symptoms. The values, irrespective of symptom burden, were 45% after 2-5 years of follow-up, 58% after 6-10 years and 38% at > 10 years after surgery. The total symptom burden also influenced the risk of anxiety and depression. Symptom prevalence remained largely unaffected by the duration of followup, except for defecation urgency. CONCLUSIONSThe number of long-term symptoms after radical surgery with a urostomy for urinary bladder cancer affects the risk of anxiety, depression and low or moderate well-being.

The major conclusion of this investigation is that the endogenous serum component LPA, is able to promote human BPH SMC growth. In addition, our study indicates that cyclic nucleotides can inhibit this effect. Future clinical studies will be needed to determine if different specific phosphodiesterase inhibitors per se or in combination could represent a new therapeutic possibility for the treatment of BPH.
