Over recent years, the introduction of miniaturized pcnl techniques such as miniperc, microperc, and ultra-miniperc has further expanded the indications for management of renal stones by percutaneous techniques this provided an alternative treatment option for management of renal stones for renal. The disadvantage of miniperc is the smaller scope used with smaller working channels and less irrigation which will lead to a longer procedure time introduction a standard pcnl (percutaneous nephro lithotomy) requires a large percutaneous tract into the kidney to allow the passage of the nephroscope. Technique that aims to replace classic pelvic lithotomy through lombotomy in cases where open surgery is indicated in europe pelvic calculi can be treated by pcnl or laparoscopy, the latter allowing for the complete calculus removal without the study conditions and signed the informed consent form were.
It is standard practise to allow the disease to stabilise for approximately a year before considering surgery one of the most important aspects of peyronie’s disease is to have realistic expectations of what treatment can achieve. In a historical study, postrenal biopsy bleeding was found to be significant only after the tract of the needle was less than 16 gauge microperc extended the concept of ‘all-seeing needle’ to perform pcnl through a 485-fr (16 gauge) tract. 54 one study evaluated flavoxate hydrochloride and imipramine 42 one study evaluated trospium 45 the panel interpreted these data to indicate that behavioral therapies can result in symptomatic improvements similar to anti-muscarinics without exposing patients to adverse events. A retrospective study failed to show significant advantages of the miniperc technique, but two randomised controlled trials comparing miniperc with rirs and the other comparing miniperc with standard pcnl showed that the miniperc has a role.
123 patients were enrolled in this prospective study from april 2015 till june 2017 and distributed into 2 groups based on the tract size used to clear the stone (group a: miniperc, 165/175 fr, n = 61 and group b: standard pcnl, 22/24 fr, n = 62) medium to large renal stones were included in the study. [4,12] these can be minimized by doing a mini pcnl rather than classic pcnl, as the former employs a smaller caliber sheath of about 12‑15 f [7, 8] many earlier series of both classic pcnl and. Miniperc – a new way to look at pcnl helal – 1997 – peel away sheath for miniperc in children jackman 1998 – small sheath with standard scope negle – 2000 – new design miniperc. Ump will not replace conventional 24fr to 30fr pcnl but simply complement it it is not suitable for large complex stones or when there are matrix or putty stones sharma, r, garg, c et al prospective comparative study of miniperc and standard pnl for treatment of 1 to 2 cm size renal stone bju int 2011 108: 896 view in article.
If they wished to be a part of the study, they were placed in the miniperc group, else placed in the standard pcnl group, alternatively a total of 26 and 40 patients underwent miniperc and standard pnl, respectively during the study duration. Abstract background and purpose: a benefit of miniaturized percutaneous nephrolithotomy (mpcnl) compared with conventional percutaneous nephrolithotomy (pcnl) has not been demonstrated as yet thus, the aim of this study was to evaluate the outcome of conventional vs mpcnl and to determine if mpcnl offers an advantage for the patient patients and methods: a prospective, nonrandomized series. Mini-pcnl offers comparable stone-free rates (sfr) compared with standard pcnl with less blood loss and less perforation 4,6,7 pain and urine leak are markedly less after mini-pcnl than standard pcnl 4,8 rirs has gained much attention because it can lower the risk of significant morbidities associated with percutaneous approach 3 the.
Biomed research international is a peer-reviewed, open access journal that publishes original research articles, review articles, and clinical studies covering a wide range of subjects in life sciences and medicine. They concluded that the “miniperc” can offer advantages associated with hemorrhage, postoperative pain and the hospital stays this report has been supported by several experts[ 19 - 23 ] knoll et al[ 23 ] evaluated the outcome of standard-(26 fr) vs mini-pnl (18 fr. Standard pcnl access tracts are 24–30f with smaller access sheaths (18fr) initially developed for paediatric use these are now becoming increasingly used in adult patients with the advent of ‘mini-perc’, ‘ultra-mini perc’ and ‘micro-perc’ procedures.

Background percutaneous nephrolithotomy (pcnl) is now popular method for removal of kidney and upper ureteric calculi percutaneous nephrolithotomy (pcnl) is the preferred treatment modality for renal calculi with a large stone burden (example, staghorn calculi) and renal calculi which have failed extracorporeal shockwave lithotripsy (eswl. Post standard pcnl, a nephrostomy tube is left with the intention of tamponading any bleeding from the in a study by raman et al fragments 2mm led to a stone-related event other studies have shown 3mm twenty-first century: role of microperc, miniperc, and ultraminiperc world j urol 201533:235-40 11 desai mr, sharma r, mishra s. Modifications in microperc since the microperc needle is of narrow caliber, it can bend if it is manipulated inside the pelvicalyceal system moreover, there is a theoretical risk of parenchymal tear if there is excessive intrarenal manipulation.
- The miniperc is associated with lesser hospital stay compared to standard pcnl(5,6)the hospital stay in standard pcnl was 48 to 69 daysthe size of the stone does not affect the hospital stay in miniperc.

Ture, miniperc and ultraminiperc (ump) are associated with similar clearance rate as the standard pcnl but they are associated with decreased hemoglobin drop. The department of urology at sechenov university is the only one in the country that performs this high-tech operation en-bloc laser enucleation is indicated for patients with non-muscle invasive bladder cancer - the muscle layer of the bladder wall is not affected. Miniperc is associated with similar clearance rate as the standard pcnl but is associated with decreased hemoglobin drop, hospital stay, analgesic requirement, and complication rates [5, 6, 7] these studies have compared miniperc with standard pcnl for 2 cm size renal stones. The study included 43 renal units, of which 21 were subjected to retrograde intrarenal surgery and 22 to percutaneous nephrolithotomy operative time was comparable for both groups mean radiation time and hospital stay were longer after percutaneous nephrolithotomy (p 0001.
