A device to be used in lower obstructive diseases of the urologic system is created. The immediate deviation of the urine either through urethral catheter or suprapubic punction, by means of a device known as trocar is the elective treatment of these medical emergencies. The difficulties to purchase such device in Zimbabwe where a Cuban medical international mission was taking place, led to the creation of a device to perform suprapubic punctions at very low prices, capable of solving obstructive urologic emergency, in order to avoid complications and to ease its use by the specialists. To create the Adjustable Trocar of Suprapubic Punction (ATSP) different disused materials were recuperated (Ex. The handle of the device was made of an orthopedic drill and the sharp portion from a stainless steel belaying pin, making in it a tip and a thread). During May 2005 to December 2006, 90 suprapubic punctions were performed to patients that attended to the Emergency Rooms or Clinics suffering from acute and chronic retention of urine due to obstructive diseases. Results showed that out of 30 patients treated with the instrument (ATSP), male sex mainly, only one developed post-instrument sepsis and no traumas due to failed attempts and/or intestinal perforations was observed; compared to the patients treated with the traditional device and non-technical improvised instruments, it constitutes a significant contribution in Urology.
