RESUMO
The article reports a case of a robot-assisted cystprostatectomy in a 36 y.o. patient with a malignant bladder neoplasm (highly differentiated infiltrative urothelial bladder cancer, Gr 2, invading the bladder wall mucosa, the multicentric growth type, with the focal tumor growth in the urethral mucosa and prostate). The ileal neobladder was constructed using intracorporeal access. Operating time was 6 hours, intraoperative blood loss was 150 ml. There was no intra - or postoperative complications. Voiding function was restored at day 10 postoperatively.

The miniaturized mass-spectrometric detector with atmospheric pressure chemical ionization (APCI) is described. The analyzer employed in this instrument is the monopole with rod 54 mm in length and 2 mm in radius, which retains its efficiency up to 0.13 Pa ( approximately 10(-3)Torr). Together with the ion source, channeltron ion detector, radio frequency power supply and preamplifier, it is packed into a case with dimension of 185 mm x 100 mm x 70 mm. Mass spectrometer with the whole vacuum system weighs about 20 kg. In spite of low power of the vacuum system, the limit of detection at ppt level is achieved. The "strong" fragmentation mode is suggested for high-specific detection of phosphor-containing substances. The detector conforms to multicapillary column attachment.
