Impact of preoperative haemoglobin concentrations on the efficiency of KTP-laser vaporization of the prostate.
The potassium-titanyl-phoshate laser (KTP laser) device produces light (wavelength of 532 nm) that is absorbed by haemoglobin, thus releasing thermal energy. This reaction causes vaporization of the tissue. We tested whether preoperative haemoglobin concentrations (Hb) affect the efficiency of the 80 W KTP laser, thus affecting the energy applied. ⋯ Haemoglobin concentrations, in the range of clinically encountered values, do not affect the efficiency of 80 W KTP-laser vaporization of the prostate. This laser technique is thus applicable in patients with low haemoglobin concentrations without concerns about efficiency.

Comparative Study Clinical TrialUrodynamic changes and response rates in patients treated with permanent electrodes compared to conventional wire electrodes in the peripheral nerve evaluation test.
Sacral neuromodulation having become established as an essentially effective new therapeutic modality, both in patients with anticholinergic-therapy refractory overactive bladder (OAB) and with chronic urinary retention. It is important to establish which patients might profit from this kind of therapy in order to ensure, by means of a peripheral nerve evaluation (PNE) test, that the implantation of a permanent stimulating device is effective. In a retrospective study we compared the urodynamic outcome of two different techniques (implantation of the permanent neurostimulation electrodes so-called "two-stage-implantation" vs. conventional PNE). ⋯ The results of this study show that application of permanent quadripolar electrodes during PNE prior to chronic neuromodulator implantation leads to significantly higher responder rates and enables more efficient patient selection.

Extra-anatomical transobturator bypass graft for femoral artery involvement by metastatic carcinoma of the penis: report of five patients.
Squamous cell carcinoma (SCC) of the penis with inguinal lymph node involvement aggravates prognosis and can cause femoral artery bleeding, hemorrhagic shock and even death. The objective of this study is to describe the use of extra-anatomical transobturator bypass graft for femoral artery involvement by metastatic carcinoma of the penis. ⋯ The use of the transobturator bypass can benefit patients presenting with penile SCC and inguinal lymph nodes metastasis involving the femoral vessels, allowing resection of extensive tumor lesions, as well as avoidance of local complications.

Does tourniquet application alter the nitrergic responses of rabbit corpus cavernosum penis? A functional study.
To investigate the effects of short and long periods of tourniquet application on corporal nerves, endothelium and smooth muscle responses. ⋯ The results suggest that long period of tourniquet application altered endothelium-dependent muscarinic receptor-mediated relaxation responses. This is the first functional study that examined the effects of tourniquet application on corpus cavernosum tissue. In conclusion, it can be suggested that if tourniquet is necessary in penile surgery the application time of up to 20 min is more appropriate instead of prolonged usage.

Biography Historical ArticleJohann Anton von Mikulicz-Radecki (1850-1905)--a pioneer of gastroscopy and modern surgery: his credit to urology.
The author presents the life and achievements of Johann von Mikulicz-Radecki and his contribution to European and world surgery. Mikulicz was born in Czernowitz, then a part of the Austro-Hungarian Empire. He was educated in numerous Austrian schools and graduated at Vienna University in 1875. ⋯ Besides his many contributions to general, gastrointestinal and thoracic surgery Mikulicz devoted himself also to urological surgery. He performed ureterointestinal anastomosis and the first ileocystoplasty on a patient suffering from extrophy of the bladder. He died prematurely at the age of 55 in Breslau.
