The average tumour size, estimated by the diameter of the resectoscope sheath equaling about 1 cm, was 7.8 cm.
In fact use of larger size nephroscope or resectoscope sheath may cause urethral stricture in long term outcome.1 Because of these issues we sought to develop a simple and effective method for removal of bladder calculi with simultaneous TURP.
Applying of sufficient lubricating agents whenever needed along the shaft of the resectoscope and using smaller size of resectoscope sheath may decrease friction between resectoscope sheath and urethra.
Both electrodes are completely insulated from the resectoscope sheath. The unit offers surgeons key clinical benefits when combined with the AUTOCON II 400 ESU.
For the laser enucleation a resectoscope sheath is used with a 30 degree lens.
These techniques range from the use of forceps, as Grainger et al described in the first published case report on resectoscope sheath extraction, (1) to the use a holmium YAG laser with a 200 [micro]m fiber to fragment the 26 French (Fr) resectoscope sheath in the patient's bladder and other laser-based techniques.
Of note, it was initially suggested that B-TURP may be associated with a higher incidence of urethral strictures.[sup.8] The current study did not find a significantly higher incidence of urethral strictures in the bipolar group.[sup.7] This finding is consistent with others and adds to the body of evidence that urethral stricture might not be a concern specifically associated with bipolar technique; perhaps more of a relationship to resectoscope sheath diameter and postoperative catheter duration.
In the interim, a plain abdominal film of the kidneys, ureters and bladder (KUB) was performed which surprisingly showed a metallic object in the bladder consistent with a resectoscope sheath tip (Fig.
After failing an initial attempt to place a Foley urethral catheter, I placed a resectoscope sheath under direct vision into the bladder following TURP.
