Statistical shape and texture model of quadrature phase information for prostate segmentation

Prostate volume estimation from segmentation of transrectal ultrasound (TRUS) images aids in diagnosis and treatment of prostate hypertrophy and cancer. Computer-aided accurate and computationally efficient prostate segmentation in TRUS images is a challenging task, owing to low signal-to-noise ratio, speckle noise, calcifications, and heterogeneous intensity distribution in the prostate region. A multi-resolution framework using texture features in a parametric deformable statistical model of shape and appearance was developed to segment the prostate. Local phase information of log-Gabor quadrature filter extracted texture of the prostate region in TRUS images. Large bandwidth of log-Gabor filter ensures easy estimation of local orientations, and zero response for a constant signal provides invariance to gray level shift. This aids in enhanced representation of the underlying texture information of the prostate unaffected by speckle noise and imaging artifacts. The parametric model of the propagating contour is derived from principal component analysis of prior shape and texture information of the prostate from the training data. The parameters were modified using prior knowledge of the optimization space to achieve segmentation. The proposed method achieves a mean Dice similarity coefficient value of 0.95 ± 0.02 and mean absolute distance of 1.26 ± 0.51 millimeter when validated with 24 TRUS images of 6 data sets in a leave-one-patient-out validation framework. The proposed method for prostate TRUS image segmentation is computationally efficient and provides accurate prostate segmentations in the presence of intensity heterogeneities and imaging artifacts.

Implicazioni medico-legali del trattamento endoscopico dell’ipertrofia prostatica benigna

We report a case of chronic urinary and faecal incontinence after transurethral resection of the prostate (TURP) and inguinal erniotomy. The analisys of the surgical techniques used in the treatment of prostatic hypertrophy (IPB) and the characterization of the complications demonstrate that many adverse effects are due to faulty surgical technique. Diagnostic, prognostic and therapeutic aspects of prostatic hypertrophy are estimated and the “state of the art” of surgical treatment is traced, including positive and negative aspects. Particular attention was dedicated to the TURP, gold standard for IPB, singling out the risks and the possible iatrogenic injuries. Scientific references prove that the frequency of such injuries is wide distributed in endoscopic treatment and can be referred mainly to jatrogenic causes. The fundamental lines of professional liability are analyzed in order to the right of injury compensation, according to civil law.

?1-adrenoceptor subtype affinities of drugs for the treatment of prostatic hypertrophy

We have used radioligand binding and inositol phosphate accumulation studies to determine the affinity at mixed alpha 1A- and alpha 1B-adrenoceptors (rat cerebral cortex and kidney), alpha 1A-adrenoceptors (rat cerebral cortex and kidney following inactivation of alpha 1B-adrenoceptors by chloroethylclonidine treatment) and alpha 1B-adrenoceptors (rat spleen) for drugs currently under investigation for the treatment of benign prostatic hypertrophy, alfuzosin, naftopidil and (-)- and (+)-tamsulosin. Alfuzosin and naftopidil had similar affinities in all model systems (approximately 10 nM and 130 nM, respectively) and lacked relevant selectivity for alpha 1-adrenoceptor subtypes. Their potency to inhibit noradrenaline-stimulated inositol phosphate formation in cerebral cortex matched their affinities as determined in the binding studies. Tamsulosin had higher affinity at alpha 1A- than at alpha 1B-adrenoceptors, and was slightly more potent than alfuzosin and naftopidil at alpha 1B- and considerably more potent at alpha 1A-adrenoceptors. However, the interaction of the tamsulosin isomers with chloroethylclonidine-insensitive (alpha 1A-like) adrenoceptors was complex. A detailed analysis of the tamsulosin data and those obtained with other drugs, most notably noradrenaline and oxymetazoline, suggested that chloroethylclonidine-insensitive alpha 1-adrenoceptors may be heterogeneous and that this heterogeneity may differ between cerebral cortex and kidney of the rat.

Role of Open Surgery

According to anatomo-morphologic studies, the authors define the role of open surgery in enucleating an adenoma, which is only partially removed with endoscopy, especially if large. Retrospective studies also show a higher probability of a further operation after endoscopy rather than after surgery, with a greater mortality risk due to cardiovascular reasons. In the four-year period from 1987–90, the joint experience of the University Urological Clinics of Padua and Brescia and the Hospital Urological Departments of Bergamo and Treviso, shows that out of 3851 operations, endoscopic treatment was carried out in 84% and surgery in 16%, with a marked prevalence of retropubic adenomectomy (84% of cases). 1989 was taken as a sample year and surgery was performed in 160 out of 935 cases, with excellent results in 87% of the patients. The authors, on the basis of their personal experience, results and literature, confirm that surgical treatment of prostatic hypertrophy is still valid.

An Objective Comparison of Transurethral Resection and Bladder Neck Incision in the Treatment of Prostatic Hypertrophy

Transurethral resection has become the operation of choice in almost all cases of benign prostatic enlargement. However, when the gland does not exceed 30gm. bladder neck incision is easier to perform, results in a lower morbidity, and is less likely to be followed by incontinence and retrograde ejaculation. We studied 2 groups of men with proved obstruction. Complete urodynamic investigation was done on 51 patients before and on 44 patients after the operation. We compared our subjective and objective findings in the 2 groups. The conclusions suggest that bladder neck incision is as effective as transurethral resection in relieving the obstruction of prostatic enlargement in the presence of a small gland.

On the pathogenesis and treatment of prostatic hypertrophy

The so-called prostate hypertrophy, according to many authors, is found in one-third of older men. The phenomena of prostatism are typical of old age in general; some think they can be seen in most elderly people. This seemingly innocent suffering, almost "physiological", is, however, fraught with serious complications for many, and often disrupts an old man's life path. Hence the great practical importance of the issue of treating prostate hypertrophy.

SUPRAPUBIC PROSTATECTOMY UNDER NITROUS OXID ANESTHESIA.

That the removal of the prostate gland is the ideal surgical procedure in the treatment of prostatic hypertrophy is now very generally recognized. The chief contraindication to the performance of a prostatectomy up to the present time, according to the consensus of opinion, has been the danger resulting from the administration of ether or chloroform. Many surgeons have hesitated to offer some of their old prostatic cases the benefits of the operation on account of the presence of cardiac, nephritic or other lesions. It is in the hope of widening the field of usefulness of prostatectomy, and of extending the splendid benefits of the operation to patients who have heretofore had the advantage only of palliative operations, that this paper has been prepared. The cases which form the basis of the paper are, so far as I have been able to ascertain, the first cases of
