An 88-year-old woman was hospitalized with the chief complaints of lower abdominal pain, miction pain and pollakisuria. Radiographs showed a giant bladder stone shadow, 12.0 x 9.0 cm in size. Cystolithotomy was performed under the diagnosis of bladder stone. The extirpated stone weighed 510 g, and measured 10.0 x 7.5 x 6.0 cm in size. The stone had four compartments of stratified lamellae composed of calcium phosphate and magnesium ammonium phosphate. The postoperative course was uneventful and the bilateral hydronephrosis improved markedly on DIP.

精巣内精子抽出術(TESE)のうち先天性精管欠損,ヘルニア術後,パイプカット術後など明らかな閉塞性無精子症を除いた44例を対象に非閉塞性無精子症で精子の回収を予測するパラメータを検討した.JSC,精巣容量,FSHで相関がある結果であったがJSC8以上の症例を除外すると相関はなくなり,絶対的パラメータとはなり得なかった.受精に関しては妻の年齢,精子運動性の有無,精巣容量が有意なパラメータとなった.マイクロドロップレット法を用いたCryo TESE-ICSIは新鮮精子を用いたTESE-ICSIと同等の受精率が得られ,無用なパートナーへの侵襲を避けるのに有用と思われたWe reviewed 44 cases of non-obstructive azoospermia treated by testicular sperm extraction and intracytoplasmic sperm injection (ICSI) from July, 1997 to September 1999 at our institutes. Testicular sperm were retrieved from 32 patients (72.7%). ICSI was performed on 29 patients and the partners of 15 patients (46.9%) became pregnant. Out of 10 patients with histology of Sertoli-cell-only, we could retrieve sperm from 3 patients (30%). Testicular volume, Johnsen's score count (JSC), and FSH were significant parameters to predict the recovery of testicular sperm from the patients, but if only the patients with JSC less than 8, are analyzed, none of them was significant parameter. Chromosomal abnormality was not a significant parameter. The partner's age, motility of recovered sperm and testicular volume correlated with the fertilization rate. Chromosomal abnormality or the usage of cryopreserved sperm was not a significant parameter to predict fertilization.
