The aim of this study is to judge the effectiveness of the new treatment of varicoceles, introduced in 1987 by Tauber: the antegradal scrotal sclerotherapy of varicoceles. From february 1996 to april 1998, we have realised 150 antegrade embolisations of varicoceles. The study is lead on 75 patients with mean time follow-up of 12 months. Patient's mean age is 20 years. 85% of patients had a grade 3 left varicocele and 15% a grade 2 left varicocele. The criterium of success rests on the lack of veinous flow-back during clinical examination, which is than confirmed by doppler-ultrasound. Clinical success is obtained in 87% of the cases and the doppler control is normal in 80% of the cases. We have 9% of minor complications, and no major complication. The number of failures in our study is higher than in Tauber' study, but is the same as those described in the other procedures of treatment of varicocele. On the other hand the surgical procedure is simple and the morbidity is low. [less ▲]

Laparoscopic adrenalectomy is possible as well on the left as on the right side using a percutaneous transabdominal approach. The exposure of the glands seems better than it could be achieved with an open method. In combination with intraoperative infusion of nicardipine, a calcium-channel blocker, the laparoscopic removal of a pheochromocytoma was performed safely and under stable conditions. In case of Cushing's syndrome, the laparoscopic approach reduces the problems related to poor healing. In all cases of laparoscopic adrenalectomy, this approach could offer the clear advantages of smaller incisions, reduced postoperative pain and incisional discomfort as well as complications related to large and invasive procedure and finally allows quicker recovery. Moreover, conversion to open surgery remains always possible, if needed. [less ▲]

A review of 20 cases of conservative surgery for urothelial tumors of the upper tract is presented. The morbidity is limited; the recurrence rate is around 15% in the ipsilateral urinary tract with a mean follow up of 41 months. Conservative surgery does not seem to carry a higher fatal risk as compared to more radical surgery. It has indications in some cases which are defined. [less ▲]

Cardiomyoplasty is a wrapping of an electrostimulated latissimus dorsi muscle flap around the heart for substitution and/or reinforcement. The surgical technique for reproducible cardiomyoplasties in the goat model is presented. The methods combine the direction of wrapping (clockwise, counter-clockwise) and the orientation of muscle fibers. A cardiomyoplasty model using right and left latissimus dorsi or left latissimus dorsi and pectoralis major as well as a split muscle technique are illustrated. [less ▲]

The authors report their experience of 148 radical prostatectomies performed for adeno-carcinoma. They expose the reasons which have led them to adopt this kind of treatment and the reasons explaining a nearly exponential increase of the frequency of the operation during the last 5 years. They underline the importance of lymphadenectomy and the safety of frozen sections of the nodes. The surgical technique is briefly commented and the (low) morbidity of the operation is reviewed. They compare the results of RPV to those of external radiotherapy, watchful attitude or immediate hormonal treatment and they conclude in insisting on the benefit of the surgical approach as far as indications (which are defined) are strictly followed.

Benign prostatic hyperplasia (BPH) is so common in elderly men that the development of adenomatous nodules in this organ can be seen as a normal age-dependent process. In this work, we used Northern blotting to compare the levels of androgen, estrogen, and insulin-like growth factor-I (IGF-I) receptor in young (age range, 23-33; n = 3), old normal (age range, 52-80; n = 3), and BPH-affected subjects (age range, 66-87; n = 15). We have also investigated in these groups the expression of genes coding for the two 5 alpha-reductases (types I and II), aromatase, IGF-I, and IGF-II. Our results show significantly increased levels of IGF mRNA in old healthy and BPH-affected subjects; the respective rises for IGF-I, IGF-II, and IGF-I receptor mRNAs were 3.0-, 2.9-, and 1.5-fold (BPH) and 2.7-, 2.4-, and 1.8-fold (old normal controls). For estrogen receptor, androgen receptor, and type I and II 5 alpha-reductase mRNAs, a marked but opposite effect was observed in adenomatous tissues only; the respective levels were 2.2-, 1.8-, 3.9-, and 1.7-fold lower than those in young adult subjects, whereas no significant differences were recorded between the two normal groups. Morphometric analysis of each tissue specimen confirmed the significantly lower epithelium/stroma ratio in adenomas compared to young or old healthy tissues. Together, these observations suggest that prostatic adenomas may result from at least two conjugate processes: one characterized by a drop in the mRNA levels of steroid hormone receptors, which might be associated with a lower epithelium/stroma ratio, and another characterized by normal aging phenomena, of which the increased production of IGFs and IGF-I receptor transcripts could be biochemical markers.

Fourteen patients undergoing kidney transplantation were studied for evidence of the production of free radicals as assessed by the measurement of vitamin E (an index of lipid peroxidation) and of myeloperoxidase (a marker of neutrophil activation) in the systemic blood. Early (2 min) and late revascularization (30 min) of the kidney were respectively associated with a significant decrease of 35.5 and 40% of the initial level of plasma vitamin E. This consumption paralleled to the decrease of the vitamin E/total lipids ratio, a better indicator of vitamin E status. Heparin administration preceding renal artery clamping resulted in a twofold significant increase of baseline plasma myeloperoxidase (MPO) level (523 +/- 214 ng/ml). At kidney reperfusion, MPO concentration rose again and reached a maximum value of 1,653 +/- 882 ng/ml, indicating the presence of considerable neutrophil activation. A return to the baseline value was observed after 30 min of reperfusion. A short discussion about the possible origin of this MPO increase is given. Taken together, these data strongly suggest that free radical production, leading to lipid peroxidation phenomena, can occur within the early phase of kidney revascularization. Preliminary data using electron spin resonance with the spin-trapping technique strengthen this hypothesis. [less ▲]

Cardiomyoplasty is a new surgical procedure using transformed skeletal muscle to reinforce or substitute for the myocardium. For the purpose of studying surgical technique and investigating basic questions, we have developed a model of reinforcement cardiomyoplasty. Herein, we describe anesthetic management, surgical technique, and the technique for iterative transthoracic biopsies. This model has proven to be valuable in several long-term studies involving more than 30 goats. Preliminary data to ascertain the efficacy of the proposed technique are provided. [less ▲]

Multiple organ procurement techniques are increasingly popular in many transplant centers. This paper describes a technique for multiorgan unit(s) explantation in rats. The procedure involves in situ preliminary dissection, cold perfusion of the thoracic and abdominal organ units as separate procedures, explantation, and finally the ex situ isolation of various organ units as single and/or multiple organ combination units. The procedure is feasible, allows for flexibility in the separation of combination organ units, and is reproducible. The exercise is provided as a training and research tool for clinical and research transplant surgeons. The technique is also presented as an animal model for clinical organ sharing. [less ▲]
