This study was done to explore the appropriate procedure of retroperitoneal lymph node dissection (RLND) to preserve ejaculatory function. The relation between postoperative ejaculatory function and area dissected at RLND was investigated in 47 patients with testicular cancer. The patients were divided into 5 groups according to the retroperitoneal area dissected. Group 1 (38 patients) underwent bilateral RLND, group 2 (3 patients) and 3 (2 patients) right unilateral RLND, and group 4 (2 patients) and 5 (2 patients) left unilateral RLND. The vertical limits of the dissected area were similar in all groups, namely renal pedicle and bifurcation of common iliac artery. The lateral limits were bilateral ureters in group 1, right border of aorta and right ureter in group 2, left border of aorta and left ureter in group 4, and vena cava and left ureter in group 5. Group 3 was similar to group 2, but the paraaortic region at the root of inferior mesenteric artery was also dissected. All patients in group 1 had dry ejaculation. Thirty patients in this group were examined for seminal emission and none of them could demonstrate seminal emission. Normal antegrade ejaculation was seen in group 2 and 4 patients, but retrograde ejaculation was recognized in group 3. Inability of seminal emission ws confirmed in group 5 patients. When consideration is given to the function of retroperitoneal sympathetic nerves, our results suggest that unilateral RLND without impairing superior hypogastric plexus should be adopted to preserve ejaculatory function.

The incidence and mortality rate of urogenital cancers in Japan are both low compared to those in western countries. However, the incidence and mortality patterns of cancer in Japan are currently becoming closer to those of western countries, and the importance of urogenital cancers is increasing. We conducted an analysis of urogenital cancers in Gunma Prefecture. The subjects were newly detected urogenital cancer patients living in Gunma Prefecture diagnosed between 1985 and 1992. Details were as follows: prostate cancer 1411, bladder cancer 1253 (male 937, female 316), renal cell carcinoma 411 (male 287, female 124), renal pelvic and ureter cancer 187 (male 127, female 60) and testicular cancer 162. Incidence rate was calculated by year, district and age, and was expressed per 100,000/year and was adjusted to world population. Regarding the incidence rate per year for males, that of prostate cancer and renal cell carcinoma increased dramatically from 8.3 to 13.6 and from 1.1 to 3.2, respectively. Incidence rate of other cancers in males showed a slight increase or remained almost stable. Incidence rate by year for females showed a slight increase or remained almost stable as a whole. Gunma Prefecture was divided into 10 districts by the range of daily life of people and the incidence rates of prostate cancer, bladder cancer and renal cell carcinoma for each district were calculated. Incidence rate of prostate cancer tended to be higher in the northern parts of the prefecture, while that of bladder cancer showed no detectable trend.(ABSTRACT TRUNCATED AT 250 WORDS)

Three patients with stage I disease and 3 patients with stage III disease were treated with laparoscopic retroperitoneal lymphnode dissection. The patient was placed in a semilateral position and 5 trocars were introduced through the lateral abdominal wall. After incising the peritoneum along the Toldt line, the colon was reflected medially and the retroperitoneal structures such as the ureter, aorta, inferior vena cava and both renal arteries and veins were exposed. For right-side disease the paracaval and interaortocaval lymphnodes were dissected, and for left-side disease, the interaortocaval and paraaortic lymphnodes were dissected. The procedure was completed successfully on all 6 patients. The average operative time was 3.4 hours for 3 patients with stage I disease and 4.4 hours for 3 patients with stage III disease treated with prior chemotherapy. All patients started to walk and resumed oral intake from the first post-operative day and the average duration to full convalescence was 21 days. Anteriograde ejaculation and erection were preserved in all six patients. Laparoscopic retroperitoneal lymphnode dissection will be a useful technique for management of testicular cancer.

We here report the incidence of different types of genitourinary cancers among the Iranian population according to the records of the Iran Ministry of Health and Medical Education. In a population-based cancer-registry study in 2005, all recorded data in pathology laboratories, freestanding cancer clinics and treatment centers, physician offices, and other state central registries were obtained with the assistance of Iran Universities of Medical Sciences and sent to the Diseases Management Center in the Health Ministry. The prevalences of urological cancers were as follows: bladder cancer 48.3%; prostate cancer 33.4%; renal cell carcinoma 10.3%; renal pelvis and ureter cancer 0.75%; testicular cancer 6.15%; penile cancer 0.15%; urethral cancer 0.45%; and other unspecified urinary cancers 0.43%. The male to female ratios for the various common urological cancers varied between 1.69 (renal cell carcinoma) and 7.75 (unspecified urinary cancers). The incidence of prostate cancer among our population was dramatically higher than in other countries of Asia. However, bladder cancer was found to be the commonest of the genitourinary cancers, especially in elderly patients, among our population.
