[Cystoscopy (1879-1979) (centennial of a transcendental invention)].

The authors make a historical review of the successive stages in Man's attempt to be able to observe directly the inside of the cavities of the human body and more precisely of the bladder, which from the start long ago, led to the apparatuses invented during the first half of the 19th Century (Bozzini, Ségalas, Bonbalgini, Fisher, Avery, Desormeaux, Hacken, Cruise, Grünfeld, Luys, etc.) until the 9th March 1879 when Maximilian Nitze presented in the Vienna Medical Society and published in the journal Wiener Medizinische Wochenschrift his brilliant invention of the apparatus which completely changed the knowledge of vesical pathology: the cystoscope. Reference is made to the successive alternations that the primitive cystoscope invented by Nitze has undergone before arriving at the present-day cystoscopes of such great precision and usefulness in hospitals. Reference is also made to another series of creations designed by Nitze, such as a cystoscope for ureteral catheterism (which, however, was of no practical use and it was not until Albarrán's creation that the catheterism of the ureters could be achieved), an operating cystoscope, a ureteral probe with a dilating ball to enable stones to be expelled from the ureter, a "camera" for endoscopic photography, etc.

[Value of cystoscopy in the study of the urogynecological patient].

The results of 350 cystoscopic studies, are presented. In 85.7%, urinary incontinence was present, and in 72% one or more of the following symptoms were present: urgency, dysuria, urinary frequency, vesical tenesmus and nycturia. The following were analyzed: age, parity, uroculture and its relation to cystoscopic findings. Most of the patients (64.5%) were 40 to 60 years old, 54% had seven or more deliveries. Most frequent diagnoses were: urethritis alone or with trigonitis (66.8%) and urethral stenosis (meatus) in 31.4%. Uroculture was done in 96% and it was positive in 20% and negative 76%. In 88% of the patients with a negative uroculture, there were other lesions shown by urethrocytoscopy. From 300 patients with urinary incontinence, only in 155 it was confirmed objectively.

[Flexible cystoscopy in clinical and ambulatory practice].

The author describes his own experience with more than 500 examinations with flexible cystoscope. General technical parameters, differences in manipulation and various problems in evaluation of findings are mentioned. In spite of much higher price as compared with rigid instruments, the use of flexible cystoscopes has been advocated because of their medical advantages and patient's comfort.
